Very nice. You must be a masochist to do this in Javascript. ;)

If you add sound, this thing will actually become useful. I only get a Framerate ~20 fps right now, but my PC is a few years old. So performance should not be a big issue in the future.

Btw.: I just played Bombjack, and although I know there is no sound I swear I could hear all the sound effects I know very very faint. I even turned the volume nob on my speakers to reassure me that it is just my imagination. The human mind is a strange thing. :)

I was really wondering how come there were no replies in this thread, but didn't have the time to post...

Anyhow, this is a great exercise that shows lots of promise. Of course a few things are needed, like sound, more speed, more compatibility, maybe gfx filters if possible (probably not), but it's really something!!! Well done!

TFM - It's using the new HTML5 standard for it's clever stuff, only some browsers will work 'properly' with this and other HTML5 based bits and bobs. The latest version of Google Chrome will do the trick. Running the site in Firefox on a very high end PC will still end up with stutter.

Ok, thank's a lot for the info. Will install Chrome and see what happens then.
Now, I also found the information onto his site, but who expects that you have to scroll down an empty page (that is displayed when using IE). You just see an error message on top of the screen, 90% below is just empty, then you scroll down a long way (depending on monitor and resolution) to find at the very bottom in small letters some message about Chrome 6+. The designer of that site should be sued ;)

It doesn't matter if you have to scroll _much_. What matters is that you have to scroll, and nobody expects that. So you can't get the information easiely, just by looking at it.
If I ask then which browser would be good, you insult me instead of answering me "Take Chrome". What kind of guy are you???

But I had now a closer look at it (Quad Core, 3.8 GHz) and I only can tell you it's soooooo slow! It crashes more often and IMHO it's a piece of filty crap.
It's quality is as good as the "nice character" of it's producer. You better go back in your box and overwork it _completely_. And if you ever come back with something usable, then please _before_ also overwork your manners - they really need it!

Btw.: @ phi2x:
The emulator indeed runs very slow only.
With ~20 fps on my system.
The biggest problem I see is, that also the complete emulation slows down here.
Can this improved by adding an auto-frameskip?
(JEMU by Executioner and also JavaCPC (which is based on JEMU) use this. You still have full CPC speed also when the frames per second are limited down)

Well, I don't know, why your emulator is so slow, but when this is because gatearray emulation or painting the screen itself, it could be a solution.

Edit: Also a disabled wait for vsync could improve speed.

Sheesh... away to Frankfurt on business for a few days and WWIII breaks up. And it'd be kinda cool, except there are no zombie nazis to shoot.

I see things did calm down in the end, so if I may, I will say a couple of words to commemorate this and then, if you agree, I'll delete the problematic posts.

This was a classic instance of flame feedback. TFM maybe was a bit careless in checking, phil was quite rude (ok, maybe you didn't mean it that way, but that's the way I read it too), then TFM started nitpicking and it all went downhill from there.

What worried me most, though, since it seems we have reached a semi-amicable solution, is the trashing of another man's work. This should never have happened, it's a real shame. Personal fights may occur, sure, but dissing a work of love because you don't get along with the creator is a disgrace :(

Now, I'm off to try it in Opera. Should I delete the offensive posts and clean the thread up?

I think that writing an emulator like this in HTML5 is very impressive and highlights the potential of the emerging browser engines. So I congratulate you on your efforts as it must have been quite a task.

Chrome supports of this because Google want Chrome to be the only thing on your computer (http://en.wikipedia.org/wiki/Google_Chrome_OS). If Chrome can run all this type of stuff then who needs Windows?

Which is why IE9 doesn't support it. Because Microsoft want you to keep their OS installed on your PC.

It's amazing though that we're going to need *really* fast PCs to do in a browser what we've been doing on desktops for 20 years. But I guess Google can't advertise on your desktop ;)

So simple:
Add code, which prevents a "update image" until previous image has not been painted.

The HTML5 video tag will let you play back videos with audio, but it's a whole different kettle of fish if you want to generate audio programmatically

Title: Re: CPCBox, your CPC emulator in Javascript
Post by: robcfg on 17:10, 18 October 10

It shouldn't be that different.

You have to decode the audio stream of the video file somewhere. And that place is the same where you should have to put your programatically created audio data.

Edit: The "Media" interface from which the "Audio" object inherits seems to have a nice set of functions for controlling the media and its rendering. I don't now if it's a must to write a codec for the media type or you can do it on the fly.

Title: Re: CPCBox, your CPC emulator in Javascript
Post by: robcfg on 19:24, 18 October 10

Do you know if there is some kind of communication between the codec and the HTML5 code running?

If some info could be sent to the codec, it would appear to the browser like a streamed file but under control of the code.

Of course it's only a crazy idea, but It seems too odd for me that you can make palette rotation in an image canvas and not something similar for audio...

Another problem I see here is:
The emulator does not run with 100% speed!
So a probably emulated sound would make a crap output.
Sad, the timing does not depend much on painting the image, because if not, phi2x could simply skip 3 frames and have less fps but faster emulation.
(Add manual frameskip could be a solution with radiocheckboxes to choose how many frames should be skipped)

But until the emu does not reach 100% speed it also makes not much sense to emulate sound.

Post by: robcfg on 21:42, 18 October 10

I think you can play an audio file within the audio tag with a different speed, that would made it work like a tracker (in some way).

Could it be possible to use a sample of a square wave and play it looped altering the volume and pitch to match the desired sound?

Ecole Buissionaire at 33fps with lots of programs running in the background (and while burning a DVD) is not bad at all!!! And it looks quite nice and accurate, though you have some sort of filtering?

Very interesting, thanks for the info. The documentation is a little unclear with the LDIR/LDDR and CPIR/CPDR where it says MEMPTR = PC + 1, where PC = instruction address. Which instruction? The ED of the first part of the instruction itself?

Am I right in assuming that MEMPTR after LDIR/LDDR (ED xx) (when BC <> 1) will be pointing to the xx, and CPIR/CPDR will be pointing to the address after the xx.

I would apply the same. I think that this "market segmentation" will be good for the users.
My emulator is focused on slow machines, with bad emulation. I have seen games (like Monty) that use different video modes in the same screen. I would never emulate that, because I will never do it as good as your emulator does, and it will slow down performance.

Also I am able to collaborate with you if you need. I admit that I have been tempted to spy your source code, because my bad FDC 765 emulation. Finally I have solved it (partially) with many debugging hours, in my own crappy code. Your "spagetti" code is better structured than mine, so I can't say which emulator is easy to read for an external programmer. It's courius how every string in your code is reversed.

That would be the hard way. There are plenty of great open-source emulators to "spy" upon, if that's your thing: Caprice, Arnold, JavaCPC...

Yes I have read some GPL code when I had a little doubt, but in that case the FDC code should be 500-1000 lines of code, and when you traslate from C to javascript you can introduce bugs.

I tried the emulator with FF hardware acceleration on. Normally I have it disabled cause it screws up the fonts rendering and I need them to work ok to do web design.

I was playing a few demos, DTC, Ecole... etc. While I was testing the emulator I was looking at 2 performance monitors that I use (one for the cpu, another one for the gpu). On the cpu, one of the cores was getting about 50-60% load, the other one about 80%, and the gpu only about 20%. The audio was still stuttering and the performance was moving between 36-43fps

So now you know!

Actually the graphics requirement are not high, hardware acceleration is only used to perform canvas stretching. The only barrier is the Firefox drivers blacklist.
So if you have an integrated graphics chip on your motherboard, it can prove useful to unplug your graphics card and use the integrated graphics instead.

Also, keep in mind that Chrome and Opera are working right now on supporting hardware acceleration. And hopefully their drivers blacklist won't be the same as the one in Firefox ;)
And in the longer run, we have W3C working right now on defining Web Audio API, which will be the standard audio output API for browsers.

Hello phi2x

The Web Audio API is implemented in Chrome dev-channel. The specification is not totally defined, but you can implement in your emulator. Unfortunately you can not choose the sample rate or the buffer size like in Firefox. There is also a transparent API here:
https://github.com/grantgalitz/XAudioJS (https://github.com/grantgalitz/XAudioJS)
that receives samples at your desired rate and do the resampling for you. The output is Web Audio API, Mozilla Audio Data Api or Adobe Flash for the rest of browsers.

I am also focused in sound, and I have problems with Web Audio API. When it works well in speccy I will traslate into Roland (my cpc emulator). If your machine is slow, try to press F9 (it uses a fastest scaling algorithm).

OK, found the issue - for sure I get no hardware acceleration in Firefox, apparently Firefox keeps a whitelist of supported video drivers, and under Linux the only supported driver is the proprietary NVidia X server. I guess the version I have installed in Ubuntu 10.04 is not good enough... Intel and AMD's drivers, or any open source drivers are "disastrously buggy" so Mozilla won't support them. This also goes for Windows OpenGL drivers also. OpenGL on OS X is fine, as is DirectX9/10 on Windows.

To go further into emulation, what's now needed is mimicking the synchronisation lag between the CRTC and the Gate Array output.
As I implemented CPCBox, there is actually no delay between those 2 chips. It makes things simpler for a code point of view, and it enables nice optimizations.

But at the end of it, it's not how the real thing works.
I tried my best to hack around to mitigate the side effects. But some demos are impossible to fix due to this synchronisation issue, and so it claims for proper emulation!

I've thought a little about it. Implications are enormous from a code point of view. Making proper emulation of this synchronization delay will be CPU intensive, and I'll have to ditch the optimization tricks I used that won't fit anymore. :(
Is it worth it, just to be able to fix a handful of demos? Given how slow CPCBox currently is, I'm not sure. But it's bothering the heck out of me. >:(

?? There are some delays.

it is known the the hsync is delayed by 2 crtc clocks before it leaves the gate-array, and is cut by the gate-array to a maximum of 6us.
this partly explains how the image is centralised in the display, and also why some values of hsync do not trigger interrupts.

I believe the same may be true of vsync, but I've not checked it.

do not forget the gate-array reads 2 bytes of memory for each crtc clock, it buffers these, then clocks them out to the display.

there is probably a delay in here, which explains why colours etc are delayed.

is it worth doing it for a few demos? depends on how far you want to go.

for me, I would do this.

I am currently investigating the dk'tronics ram expansion and how it's operation differs on a 464 compared to a 6128.
so I can emulate this in arnold correctly.

how far do you go with the timing of the instructions? do you do "inter instruction timings" where you consider that the i/o operations occur within the timing of the instruction? (e.g. outi, outd, the time for i/o happens before the instruction has finished executing), *this* will also explain why you have to work around the timings?

That's another synchronisation issue: synchronisation between Z80 and GA. There is a 0.5µs lag between these 2 chips. Palette is modified right in the middle of a Z80 "µs cyle".
It's really the worst of those synchronization issues. And it's interesting to note that no emulator emulates this. I don't plan to do it either!

The display output shows the palette change 14 (MODE 2) pixels into the 16 pixels read in one go. I think this may be slightly different on the Plus also. So the actual change happens 14/16 * 4 T-States in, ie. It's aligned to 3.5 T-States. This could be emulated by getting the renderer to render the first 14 pixels, then do and internal palette update if necessary, but it would involve a lot of overhead just to get the emulation 2 MODE 2 pixels correct (only 1 pixel in MODE 1, and no difference in MODE 0).

Try a thing like this in your CRTC emulation:
(I only emulate CRTC 1 or 0 so you will understand what I do here)

Code Select

// Some scrollers use register 8 (CRTC 0)
// and register 6 (CRTC 1). This routine makes them visible
// JavaCPC is the only known emulator which emulates booth correct!
    public void checkHDisp() {
        if (hDisp) {
            if (CRTCType == 0) {
                if ((reg[8] & 0x030) == 0x30) {
                    listener.hDispEnd();
                } else if ((reg[8] & 0x030) == 0x00) {
                    listener.hDispStart();
                }

            } else {
                if (reg[6] != 0) {
                    listener.hDispStart();
                } else {
                    listener.hDispEnd();
                }

            }
        }
    }

and call it every GateArray cycle...

Oops, my post earlier was completely wrong. I was thinking of the HSYNC blanking timing on the standard CPC I think. The Grim documentation is accurate for palette changes.

@Markus, it appears JavaCPC most likely delays the palette change one whole extra microsecond for you to get the correct screen output on Vanity.

WinAPE also has a slight interrupt timing issue which I never tracked down. I'm not sure if it's common to all emulators, but I dicussed it with someone back on CPC Zone. About the only things I'd really like to get back from Malc are those posts.

Well,
sure a FPS rate of 900 could be cool.
But, as far I understand it, CPCBox is an experiment.
And it's a cool thing to have an emulated CPC in javascript with extremely accurate CPU and CRTC/GateArray emulation.
Sure it could run better, but isn't that a thing for the browser-providers to improve javascript execution speed?
On the other hand, Roland runs much smoother. But also it's emulation core is not so complex than in CPCBox.
So, both emulators are cool in their way:
- CPCBox is highly accurate and will run better in the future (I'm sure)
- Roland is a speedy emulator which is good enough to run games in it.
The fact, that both use javascript, apologizes the lack of speed ;)

Hello Phi2x

I think that Syx wanted to say that we would like to include cpcbox in amstradcpc.es webpage. That page is not exclusively for Roland and we don't earn money with it (as there are no ads).

It would be interesting to access with your emulator to a huge database of 4000 games without loading local files. Also, my emulator is poor in accuracy, and doesn't work with many games with splited modes.

Thanks for your great emulator and your regular updates.

Nope, I'm not interested at all in seeing CPCBox used on other websites.
In fact, this is partly why CPCBox is NOT an open-source project, to block this kind of initiative to happen!

But you have more interesting alternatives anyway: I think you should work with DevilMarkus on that project.
His online Java emulator is open-source. And it is already used on different websites, like cpc-power.com (http://cpc-power.com/)

Another advantage is that its emulator is accurate AND fast. So it would certainly fit better with what you're trying to do ;)

You could have saved some typing, as I wasn't referring to the license scheme :D I believe each author's choice of license is their own business, though:

a. for instance, an open-source Batman would lead to better demos and
b. Open source does not prevent, of course, IP.

I was talking about not wanting to incorporate the emulator in other projects.

Erm... not quite. Going closed-source does not prevent you from allowing the emulator to be used in other projects and vice-versa. One is a condition subset of the other that does not necessarily affect the end result. You could very well keep the emulator closed but allow it to be used - how on earth would you lose IP then? As for piggy-backing, aw, come on, we're a small community where there are people trying to offer something to the rest of it. If you see it as piggy-backing and play it all defensive then you see it wrong...

Winape, for instance (as other emulators, too) isincluded in the CPCGamesCD which is a wonderful package and builds on top of other people's efforts to present something really nice. Honestly, I can't see how *anyone* could lose from it. Has zit to do with who holds the copyright, who is credited and who has the right to make millions of €€€ off of it.

An emulation community's prime aim, raison d'être and -really- survival prerequisite is sharing and spreading. If we kept everything separate, in silos and with limitations in use then we'd be far, far behind - especially a small community like ours (the Spectrum and c= communities are large enough to be able to support commercial projects).

PS Oh, also, an open-source project doesn't automatically mean 'free'. It could be commercial or donationware, too.

I just removed 1-2 classes (Which contain personal data like a full mail account)
But with a few changes you still can build JavaCPC from these sources.

Quote from: Gryzor on 11:41, 30 August 11You could very well keep the emulator closed but allow it to be used - how on earth would you lose IP then?

Gryzor, many people seem to think that Open Source = Public Domain or Open Source = GNU license and that making the source available somehow makes you lose copyright. Or that Open Source and restrictions on how and where the project is used are mutually exclusive. Which of course is not true at all, because there are many other licenses besides GNU and BSD. I think Stallman's evangelism for GNU is the problem, because it has created this impression that Open Source has to mean a project can be reused by anyone without even asking and that is has to allow users to distribute modified versions, etc. But that's actually GNU, not Open Source.

Title: Re: CPCBox, your CPC emulator in Javascript
Post by: Gryzor on 12:33, 30 August 11

You're 100% correct, this has been a big issue for several years; but I'd expect that everyone who cares about IP would know it by now - or at least do a cursory google search to read on the matter. As a matter of fact, I just did, and I found articles dating back several years explaining the difference in no uncertain terms.

Stallman does have some merits, but of course you can disagree with those; after all, he's ideologically motivated, and his position includes quite a bit of hypothesizing and theorizing. On the other hand, laws and licenses are facts, not theories...

Can someone explain to me in clear terms what would then be the value of CPCBox?
Then, it would just be a snail slow Javascript emulator where all the advantages were sucked up without effort by his competitors.

@phi2x:

I think that the day that anyone discovers how to work those rasters in other emulators, CPCBox will be again at disadvantage for being written in JavaScript. I mean, it's ok as an exercise, and some time in the future, you'll be able to run it at full speed, but by not sharing your knowledge you're only making everyone else's life more difficult.

And I bet, you've read information about the CPC that wasn't written by you, so you used knowledge that other people shared. You're not competing with anyone here, users will choose the emulator that best suits their needs, and that hasn't to be the most accurate. Of course, if everybody could get accurate emulation, then the extra features of the emulator is what will make the difference.

That's my two cents.

Post by: Bryce on 11:57, 31 August 11

I swore I wasn't going to join this thread, but I will:

@Phi2x:
First of all, whether you release the code or not is completely up to you. Don't let other people put you under pressure, and don't take too seriously what other people say about you or your work (here or anywhere else). With hardware it's very similar situation, some people (like me) release their entire plans, schematics and layouts and some prefer to keep it all a secret. I believe that "Copying is the highest form of compliment", so I don't mind if people use my stuff to come up with better/other hardware. The fact that they needed to copy it, means they think it's really good, but weren't able to do it themselves. It also improves the quality of hardware/software available for our ~~obsolete~~ dis-continued but much loved 8-Bit machines. If you are worried that your work will be claimed by others as their own work, then you just have to make it MORE public, by releasing a technical description in the Wiki and calling it something like "Phi2x Rastering" or "Phi2x Rastering Method", that way, no matter who copies it, it will always be seen as your achievement and referred to as such.
Much the same happened with the ACID crack last year. Nocash cracked the ACID, he could have kept it for himself, but he released the information although he hadn't yet created the hardware (and still hasn't), so even if I released hardware that required just one transistor and a diode to replace the ACID, it would still be thanks to nocashs information and acknowledged accordingly.
It's all a matter of view point of course. I'd prefer to be seen as the person who improved EVERY emulator rather than the person who wrote one of many emulators. But that's just me, you might see it completely differently.

Just my two cents.

Bryce.

I'm very sorry for DevilMarkus, but it's up to him to clean that mess. All the necessary information is available on the web. I certainly won't code his emulator for him.

Even if I use code like this, it's not your turn to moan around here like a stupid.
I never said that JavaCPC uses a clean code like CPCBox.
I'm not god, and I don't behave like him.
And I never said that I know about emulating things.
As you perhaps have seen, I am using the emulation core from JEMU and this emulator is very restricted in it's features.
Sure, I did also many improvements, but also I am doing a few patches to make some things work.

Ahem, maybe this is going a bit too far.

The thing is if phi2x would have said at the beginning of the topic that he's not sharing his sources because it is a clean emulation, and maybe pointed to some useful info, this ugly discussion wouldn't be taking place.

Also, the point in sharing is that no one is born knowing everything, and emulation is a tricky subject, so knowing how phi2x organized his code, may help people understand a better way to do things and improve. Of course, he's in his right not to do so, and that's the end of it.

Post by: Gryzor on 20:15, 31 August 11

Wow, lots of replies,the fun continues! Let's see...

@phi2x: how on EARTH using the emulator in another project would mean "throwing you out of control of your ownership on CPCBox" is beyond me - and, I suspect, anyone else's with a modicum of common sense. Or you're meaning to say that all the authors other emulators (and not only for the CPC) that are used in a myriad of third-party projects have lost "control" and "ownership"? If nothing else, those third-party projects have raised the emulators' popularity and awareness. Boy, you should probably work for RIAA or something, I hear they're good at distorting reality and sense.

If you didn't understand the video then, well, nevermind, obviously you have no feeling of sharing. But one wonders, why on earth would you release your emulator for free after all?

And even though I didn't mention open source myself, you actually respond as if I did. Of course, with open source the advantage is PRECISELY that people can build on others' work and produce something even better, that's the magic. Noone's losing their copyright or credit, but the end result is very positive for the common good, especially in a closely-knit community as ours. If you can't feel that, well, each to his own.

*competitors*? For the love of god... I don't have enough facepalm gif's to express my reaction...

Oh! Oh! I got an idea! Let's prohibit linking to the wiki, or using the knowledge that is there, to prevent 'competitors' from doing things with OUR material!

The diploma analogy is ridiculous, to say the least. A much, much more appropriate analogy would be this: imagine you got your engineering diploma and made a discovery that could help the entire society if it got open and free. Maybe a pysics law or something. Now imagine keeping it for yourself; not much future for science I suspect... As Robcfg pointed out, I really doubt you came up with the emulator without sourcing freely available material. The fact that those people made their knowledge available, and that you used it, merely proves that this model actually works. Taking freely available knowledge and others' efforts and using it to built something closed is nothing short of hypocritical.

Also, going open source does not prevent competition - of course. It only promotes it...

But, anyway, once more: it was YOU who brought up the open source thing, I merely asked about using the emulator in other projects which is, of course, a totally different issue. This is precisely why I didn't reply to your open source bullshit -because it was just an effort from your part to shift the issue. NOT so clever.

The fact that the demoscene does not agree with me doesn't prove much. I do understand the competitive spirit of the demo scene, but this doesn't mean that we wouldn't be enjoying more and better demos if the knowledge was public. Ahhh see what I did there? It's called "logic".

Claiming that open source =/IP is totally stupid and a load of crap. This has been done to death over the years - you obviously don't understand the concept of IP.

And how the (c) symbol has ANYTHING AT ALL to do with using the emulator in other project is, again, beyond me and logic. Its quite obvious you don't understand the most basic things behind copyright, creativity and IP. Or you didn't know that everything (EVERYTHING) on the wiki or elsewhere is copyrighted? What's more, under our license, typically what you create using knowledge found herein MUST follow the same license.

...and then you attack Marku's emulator... as if this proves anything AT ALL? Yes, patching is a bad emulator practice... so what??? Man, you're all over the place...

@Mav: no, noone talked about going open-source but Phi2x himself. All I asked was why he wouldn't allow the emulator to be used elsewhere.

@Bryce: you hit it right on the head; it was actually what I was thinking - instead of staying in "history" as the author of a great technique that helped moving emulators forward he'll just be that Scrooge who made something, somewhere and was afraid of everyone else.

This is very nice. I especially like the fact the user interface is not intrusive (the clicks in left/right borders to display menu is well designed).

I wonder who will be the first to propose a full-featured, web-based development suite like Bespin (http://arstechnica.com/open-source/news/2009/02/ide-in-the-cloud-mozilla-labs-browser-based-ide-prototype.ars (http://arstechnica.com/open-source/news/2009/02/ide-in-the-cloud-mozilla-labs-browser-based-ide-prototype.ars)) adapted for Retro (or CPC) development (including an emulator).

Yes, it would be CPU-intensive but still - we all know this is the future, right? :)

I was giving it a try again, I have a Phenom X4 955 BE (3,2Ghz), 4GB of ram and Windows 7 64bits. I was testing it with the "From Scratch" demo.

On Firefox 9 the emu runs at 50fps most of the time. The drop in fps is pretty rare and barely noticeable.

On the latest stable version of Chrome (16.0.912.75 m) I get about 21-24fps.

Meanwhile in one of the latest Chromium builds (18.0.1001.0) I get 46-48fps. It won't reach 50, no idea why.

I've had the 3 browsers running at the same. Right now Chrome is the one that requires more processor power, almost the same that the other 2 browsers together, I would say.

As you say CDT/TZX is too much complex if you want to support everything, although is very helpful to hack and fix... (i have made a few tools), if PZX is a more clean and it's easy to convert all the TZXs and we don't lose anything, then GREAT!!! :)

But aside of one "digital" format, we should support an "audio" format, too. And CSW is perfect for it and you can get a WAV easily from it.

The rest of formats can be generated from these two.

Well, then if everything can be reduced to PZX, then my emulator only would suport this format and i would make a tool to convert from every format to PZX ;D

It'd be nice to have a simple, neat format to supersede all others and could easily produce reliable sound files. However, the difficult part is this: you'd need to check every file you convert, and this would take ages...

Already at the beginning of 2011 I was absolutely amazed about this crazy project! An Emulator for a whole 8bit machine in JAVASCRIPT? First I couldn't believe it at this time, but then I saw, that it really worked.
In the beginning of the 2000er for me Javascript was something like Basic in the beginning of the 80ies. Nice to use, but slow. But I know, it's getting more and more powerfull.
When I saw CPCBox the first time in early 2011, it was already fast enough on my Computer, and I was really wondering, how someone could be so crazy to start such an unbelievable project.

[ This attachment cannot be displayed inline in 'Print Page' view ]

Now it runs better and better, and today I had a lot of fun to see SymbOS running on CPCBox "in Javascript" (http://www.cpcwiki.eu/forum/Smileys/SoLoSMiLeYS1/grin.gif)

@Phi2x: Thanx a lot for these very nice compliments! :)

Anyway I think CPCBox is another impressive step after Marco Vieths very first CPC-Emu for MS-DOS or after Richard Wilsons really perfect WinApe Emulator for Windows (Delphi) or his JEMU (Java), as it again enters another world of actual technology. I think there is nothing else comparable for other 8bit systems yet (the C64 JS emu [JSC64] seems to be still very crappy?).
Keep on the great work! In the past it was an amazing proof of concept, now it's a full working and very accurate reality :)

Prodatron

Well that is, what I remember. Maybe 1-2 other ones appeared at the same time or a little bit later (like Arnold or !CPCemu).
At least with CPC-Emu Marco Vieth created the first version of the standard disc format "DSK" which was later used by all other emulators ;)

Checking converted files is a task that's a perfect fit for crowdsourcing.
The checking will then be handled by all the people (dumpers, users...) that will be interested in replacing their CDT with PZX. It would be a smooth and gradual replacement.

That is true, this could be organised between members of a community. But yes, it's not easy changing default formats, there must be merit to it!

EDIT:
OK, you got it... ;)

With a perfect but improbable "linear palette", the 3 grays strips have to look the same on the light, middle and dark part.
On a real CPC, it may look more blue, or red or green, depending the resistors inside the computer.
So, you can adjust your CTM and/or fix CPC resistors using this tool to get a best display result.

It's always greenish

The greenie palette I use, was also measured by Grim ;)

Edit: Think, that a greenie would just show green values: What would it result in? Into only 15 green colours. But a CPC has 27 colours (green tones)

And here we find the most important problems for emulators, which are 8 bit RGB based:
We only can difference between 15 values (0x00 - 0x0f)
Thats why we need at least RR,GG,BB values

There's no CPC emulator on iphone because that goes against Apple policy.
Apple forbids and rejects any app that is submitted to them that contains a VM that can execute arbitrary code. :(

I don't have iphone / ipad etc so I'm not 100% sure, but I think I read that this rule has been unofficially dropped and there's suddenly a plethora of VM type things, including development environments for interpreted languages.

But I guess, emulators are still probably in the area they want to discourage because people playing free games on an emulator aren't buying games on the app store...

After upgrading to ios 6 cpcbox works ! But i can.t play on it as it doesn't support touch control. I guess it'll work with Bluetooth keyboard ? Or maybe you could implement some kind of on screen joystick ?

I agree it would be cool to have touchscreen controls, but it's not high priority for me now.

Nah, not really. Even games specifically designed for touch controls can't pull it off most of the times...

Indeed. The only games I've found that I really enjoy and play again and again are either very simple ones, control-wise (like Canabalt) (or, even better, I must run!), or needing just simple clicks like defense titles (Anomaly Warzone Earth FTW!). All the other control styles - I've played some games that would have been fantastic on a pc with physical input devices, but dropped them within minutes on my mobile.

Btw, the actual CPCBOX Version runs fine on my Android Smartphone (Samsung Note II) in Firefox with about 12fps :) Thats not bad for a mobile I guess. It doesnt run with Chrome or the standard browser because of a missing Html5 Api.
I just have to fins out how to activate the touchscreenkeyboard...

}

I call it every key press and key release.
E.g.:

Code Select

public void KeyPressed(KeyEvent e){
    translator.translate(e, localkeys);
    computer.handleKeyEvent(e);
}

Works fine ;)

It's amazing how far your project has come phi2x. Congratulations!!! :)

The first versions were practically unusable in my computer, now i get a solid 50fps (although in full-screen mode only 30 fps :P) and of course, the most accurate cpc emulator (great Z80, pixel perfect rasters, ... :) ), so accurate that these days CPCBox is my last test, before checking in the real machine.

I think that you will be interested in the new ZEXALL test (faster and with tests for the recently discovered CCF/SCF flags) that Patrik Rak is working, you can see more info in this thread (http://www.worldofspectrum.org/forums/showthread.php?t=41704).

Jeez... The Z80 is a great little device, but things like that just seem unnecessarily complex and obscure. ;) But I'm definitely glad there are people who care that much about accuracy.

Quote from: Patrik RakWell, if we are lucky, it will behave in such a way that single bit is enough to represent this state. OTOH, when you consider how F register works, it would make sense if there was some place to assemble new F, and then just store it to F. The way how F is paired with A for PUSH/POP AF and EX AF,AF' furthermore makes F seem like an ordinary register, so having another place for flag assembly makes sense.

I really wish F was an ordinary register. Can you tell I'm kinda running out of spares at the moment? :D

A long time ago, i would think the same... but while coding pac-man, i had a bug where the right eye of the ghost was an 0 (Ghost in the Shell eyes :P ), instead the correct tile. And this bug only was visible in Caprice, CPCBox and the real machine. The problem was related to bad flags emulation, it's because that i think it's a great idea the emulators pass these tests :)

Sure :D , that is the only reason for coding a little in the 6502, then you will feel free again :P

And after use the alternative registers, we always have the stack, sm-code, I, the high bit of R, the second I/O port in the PSG, ... :P

Oh, definitely, I'm very glad that people care enough to find these things out and then emulate them! What I meant was that it's just a bit of a shame that this otherwise very cool little chip has some major peculiarities like this, especially for the dedicated programmers of emulators, etc. :)

QuoteSure :D , that is the only reason for coding a little in the 6502, then you will feel free again :P

Haha, maybe some other time, when I'm not running out of the Z80's many more registers! I can only imagine how much more free programmers felt who had been using the 8080 when the Z80 came out and added the alternate set of registers. Especially if you're not using interrupts, they can be a massive advantage. I do wish IX/IY were more useful, though; I've been coding something with data arranged in a struct-like format, and I have to do all sorts of acrobatics using INC/DEC (H)L, so I was disappointed when I calculated that doing it via IX/IY would be quite a bit slower and thus probably not worth the extra readability. The only real use I've found of IX/IY so far is to use the undocumented 8-bit IXH, etc. as counters in outer loops, seeing as operations on them are only 1 NOP slower than the equivalents on H/L

QuoteAnd after use the alternative registers, we always have the stack, sm-code, I, the high bit of R, the second I/O port in the PSG, ... :P

Ah, SP. I love SP. Who needs a real stack, anyway? :D

Quote from: phi2x on 23:07, 10 December 12I've noted that OCP Art Studio use the Kempston mouse positions as if it was for a 640*400 CPC screen. But with my PC settings and my simple optical mouse, it's totally unusable if the mouse is not slowed down further than what OCP does.

So in my implementation, I first tried to divide the sensitivity by 2 on each axis. That means that CPCBox is working internally as if the CPC screen was of 1280*800 resolution. It still felt a bit too fast for OCP, but it had very much a PC mouse feeling to it.
I then divided it by 4 on each axis, so it's exactly as if the CPC had a 2560*1600 resolution! Then it felt a bit slow, perhaps even painful, to move the mouse over the screen.

What I understood now is, that you are currently transfer the relative movement of the PC-mouse directly to the emulator (with some multiplications/division). What's about transfering the absolute position of the mouse pointer (when it's over the emulator screen area) to the emulator?
Let's say:
- emu window is 960x600 (without border), CPC is in Mode1 320x200
- PCmouse is at 96x60 and moves to 288x180
- this would be 32x20 moving to 96x60 on CPC side
- emulated Kempston mouse should move 64 in X and 40 in Y direction
- when entering and re-entering the window, there must be some special tricks to handle the emulated mouse in a good way
I think this is how Richard is doing this in WinApe with the SYMBiFACE II mouse, which works quite good.

Would this be realisable or doesn't it make sense??

Won't it depend on what the users mouse has been set to on the PC? The DPI resolution can be set directly in the mouse, and also in windows depending on what the user likes, the CPC mouse movement will then be similar to what the user normally uses. So ph12x method does make more sense.

When I was designing the AMX Mouse adapter, I found that the mouse had to be set to it's least sensitive setting, otherwise the pointer shot across the screen with even the slightest movement of the mouse. Due to no PC being present, my adapter sets this directly in the mouse, but even then the PIC further de-sensitises the mouse movement by ignoring any movement below a certain threshold, this removes pixel-jitter. The final result was that about 3cm mouse movement was required to move the pointer from one side of the screen to the other.

Do you talk about the RTC of Dobbertin? (I guess yes, since you mentioned the Time ROM).

If people want to know how to program hardware they usually start to disassemble FutureOS, but we can't wait that long, can we :laugh:

Now, how to read and write from the Dobbertin Smartwatch?
The watch itself is installed like a ROM. And as you know you can read from a ROM. So that tells you how to read from the Watch.

And writing? Writing is done by reading from prefinde addresses. For example wrinting from XXX1 writes an "1" and reading from XXX0 will write a "0" to the RTC.

And yes it's done bit oriented.

You need Z80 code for it?

Well, to be honest I don't have any time for scanning and updating the Wiki. PM me if you need help / sources, I can not post any source here, because I don't have permission of releasing it into public. (I talk about discs I got from FA Dobbertin in May 2012, they are all DSK now, but still not free for public release).

EDIT: I may get permission of release soon, but I have to be careful. Small routines would not be a problem though - I think.

Here's something completely unrelated, but really the news is of importance (when you remember what happened in the past in this thread)!

According to this post, MAME will switch from their current not-for-profit license to the BSD license:
David Haywood's Homepage » The End? Newer Update (http://mamedev.emulab.it/haze/2013/10/15/the-end/)

Basically, it means that everyone is now authorized to make commercial exploitation of the MAME sourcecode.
And that decision has been taken without consulting the people who contributed in the project.

So, at the moment, I'm having a thought for all the volunteers that believed in the lies of the MAME team, contributing to the MAME project naively believing that they were protected by the MAME license that there wouldn't ever be any leechers legally making money out of their work.

The moral of the story is that if you decide to publish your code with an open-source license, you'll loose every concrete control on the code you worked hard for.
And there's just enough malevolant people in this world that it won't be long before those people will rip your work and exploit it for their sole profit.

The proof has been made by the MAME team :(

Haze loves his drama :)

Current situation is: MAME core will be BSD, and MAME and MESS devices and drivers will be licensed according to the wishes of the author(s) (MAME, BSD, LGPL, or GPL).

The MAME license is essentially BSD with a non-commercial clause.

Taking those malevolent people to court costs money. MAMEdev doesn't have that sort of money.

Title: Re: CPCBox, your CPC emulator in Javascript
Post by: Gryzor on 20:31, 20 October 13

A 'malevolent' person could equally take any other emulator out there and sell "it" (actually they're not selling the emulators, rather they sell compilations of ROMs and programs; that's entirely different). So while I understand your way of thinking the overall picture doesn't change...

I have to say I really like CPCBox - it's nice to use the same emulator regardless of the computer I'm sat at at the time. My only gripe is the default AZERTY keyboard, which confused the hell out of me for the first few times I used it. Is there an option to switch to QWERTY? If not, is that a planned update for the future?

I just tried using CPCBox to test some tape functionality (that's another matter) and found I couldn't even try CPCBox with my own tape at all... Why?

Well, choosing the 464 configuration with a tape player lets me select my tape image, but I can't RUN" because there's an AMSDOS ROM loaded and I can't switch to tape mode because I can't type | nor it seems any punctuation apart from a comma.

Thanks for putting in the English keyboard option.

Please note that on UK keyboards the " and @ are swapped from the US keyboard, so in CPC Box the "{" is showing up for shift-2, and the quote for shift-' (to the right of ;).

There might be other similar issues.

You're going to have to dig into Web Audio API if you want sound back.

Technically speaking yes, the javascript code that is fed to the browser is visible to everyone via the F12 devtools of any browser.

And that explains why there's so much javascript obfuscation tools that currently exist ;) .

Their goal is to protect source code from being stolen, or being tampered with.

It's sad but counting on a simple copyright banner to protect your work will just make crooks laugh at it while they're ripping it.

Unfortunately, all you can do is change variable and function names and remove all the whitespace so the code is hard to read, then someone just
reformats it in NetBeans or Eclipse and works out what the functions actually do. Mind you, Java is not much better, there's tools like JAD can rip apart
a Java class file, and a good assembly hacker can rip apart x86 (or Z80) code fairly quickly (this I have done, eg. Frogger and Snapper (6502)).

Hi,

I integrated CPCBOX on my personal site to play online.
I wanted to congratulate you for this emulator, it's really good work.

I took the time to read all the comments about your emulator. But I did not find any trace on the next version you wanted to make.

I admit that if the future version (if there is one) could take into account the sound it would be really a plus.

Otherwise, I did not find how to load a .dsk file in javascript. I use snapshots, but some games need to access the disk.

Finally, here, I really wanted to congratulate you and I really hope that there will be an upcoming version.

Good job.

The reason is that my goal in the future is that my emulator will also be able to emulate some other computers than just the CPC.
So it won't make sense to still keep the CPCbox name.

Any chance to release the code from the old version considering such deep change in the emulator?

On the other hand, is there any way to pre-load an specific rom when the page loads? I'm trying to automate some tasks with Puppeteer like loading a game and pressing some keystrokes but I wonder if there's any way to load a rom directly to save time.

Nope. I don't plan to release the source code.

Okay, no worries. I thought I could use the emulator in a fancy project but I'll need to check out other options. As said, I want to automate the interactions with Puppeteer to create an AI agent which plays a game and CPCBox was great enough but without being able to include some features it doesn't feet my needs.

Happy New Year everyone !

Hi PhilZeVibe,

I take the liberty of asking you about CPCBox.
I wanted to know if with CPCBox, it was possible in javascript, to load a DSK file from a URL in the reader without going through the selection of a file (as for the snapshot)?
I've been trying for months, but I can't.
If you have advice or an idea, it would be nice.
If not so be it ;D

Hello PhilZeVibe,

Have you started your new project ?
Still developed in JavaScript ?

Hi PhilZeVibe,

Another question, in the next version, will it be possible to read the RAM?
It could be used to recover the player's score.

I do not have an answer to my question and I see that PhilZeVibe has not connected since March 20.
I hope he is well.

I'm glad to hear from you. Having no answer I was afraid that you would be a victim of COVID19

Great, this is good news for RetroVM.
I watched several emulators, and it is really CPCBox that I prefer even if the big problem is the sound.
It's a good job. Strongly the release of RetroVM. ;D

Best regards,

Hi,

While searching the internet a bit to see if the RetroVM project was progressing, I found an "@retrovm" account on twitter. It is not you ?

Hello,

PhilZeVibe, the creator of CPCBox, seems to have left the forum.
No activity for a while and all these posts have been deleted.
His site no longer works either.

Does anyone know if they have completely stopped CPCBox?
Do you know if it is possible to contact him?

It seemed to me that he had other projects for his emulator, but he no longer gives any news.
I hope nothing happened to him.

Thanks in advance to anyone who can provide info.

See you later

That's what you do if that CPC thing gets over your head, you want to end that and make sure you never come back.

I don't get why people delete their posts like this, it's one thing to just leave, another to try and remove old posts and evidence, shame as its a bit of history gone that might prove helpful to someone else in the future.

That. I think it's a total asshole move to be honest.

So no one has any news then if I understood correctly.

I searched on different forums, but I couldn't find any other Amstrad emulator developed in JavaScript. Does anyone know of any?

This one looks very promising: https://github.com/floooh/chips

Examples: https://floooh.github.io/tiny8bit/

Post by: BZHGames on 21:05, 17 February 22

Thanks, but Tiny8Bit is already available on my site. It has the advantage of having sound unlike CPCBox, but I find it less good. All games do not work and it is not possible to make screenshots in html5.
Are there others?

Now that we are talking, have you considered at least adding a link to the author's website -if it exists- when you add a game?

It would be nice :)

It would be nic

For some games there is already a link. But it's true that for indie games, I will have to do it systematically.

Internet never forgets.

I met Phy2X at the Revision demo party in Saabrücken some years ago, and he was a nice guy.
His JavaScript CPC Emu was revolutionary for this time. I think most other platforms followed later with a similiar emu, he was (the?) first.

Hope everything is ok with him.

Hi everybody,

Unfortunately, we have no news from him and his new project. :(
Is there anyone else planning to make a JavaScript emulator?
I'm looking on the internet, but I can't find anything. Too bad I don't have the skills to develop one myself.
I am a C# developer, I have only a few notions of JavaScript.
I think that even with training, I will never be able to develop an emulator. It's only for the gifted ;D
