Looks nice, although the play key on the cassette looks like it is broken.

Devilmarkus · « **Reply #276 on:** 14:04, 17 May 11 »

Well it's state is "pressed" so it appears darker than the others

All tape keys which you "press" (click) appear darker then to see which button is pressed down...

steve · « **Reply #277 on:** 23:40, 17 May 11 »

No, when you press a key on a real CPC tape deck, the key goes down at an angle whereas your key goes straight down as if it were not connected by a metal bar to the rest of the tape drive.

In a real tape deck I also don't load a CDT or TZX or CSW or WAV or MP3

I suppose it does not matter whether it looks right or not.

Well, Steve, everything has it's limitations. Also Java and designing GUIs.
But I tried my best to keep it as detailled as possible.
And: Dear Steve, only for your eyes:
A little virtual-tape-drive-mechanics-demonstration:

Don't worry, when the sound fu**s up... I enabled the drive turbo somewhere.
Also my recorder is not the best with Win 7

As I said, It looks nice.

I quickly updated the beta download...

Download

Fixed a few bugs.
- Major bugfix in paint
- Major bugfix in GateArray emulation and display routines
- A few minor bugfixes
- Replaced monitor mask 1 by a new one (nicier style)
- Fixed Advanced Mame 2x and Eagle 2x display filters (not MODE 0 optimized (yet))

Looks fantastic... Thumbs up!

Devilmarkus · « **Reply #284 on:** 20:54, 27 May 11 »

Still working on + emulation like a geek!

Missing:
- Still a bug somewhere in memory! :'(
- Split screen (by ASIC)
- DMA - Sound
- Who knows?!?

JavaCPC - CPC+ emulation (Work in progress)

Devilmarkus · « **Reply #286 on:** 23:40, 28 May 11 »

Live-test for you:

http://retropower.eu/CPCInAJar/cpcplus.php?large=true&dsk=Robocop.zip
http://retropower.eu/CPCInAJar/cpcplus.php?large=true&dsk=NavySeals.zip

Keys: Numberpad 1-9 = F-keys (F0 does not work because I use it for local usage)
Joystick is mapped to:
HOME = Up
END = Down
DEL = Left
PG DWN = Right
INSERT = Fire 1
PG UP = Fire 2

And don't expect something very special! It's still in a very early progress...

Well, in fact, getting the correct sprite coordinates (Especially the values between FF00 and FFFF) is the pure horror!!!
But I hope I got it now working properly.

This demo almost broke my brain:

Tell me about it...

I thought to myself it would be a nice idea to use the hardware sprites for a scroller as I could keep the 16x16 MODE 1 resolution over a MODE 0 background. But then I had a tough time because I wanted to make them to move in a sinus, and because the sprite on the left is recycled to be the sprite on the right I had to calculate where it should be in the sinus wave when it reappeared...

In the end I cheated and made the whole sinus a multiple of 4 (I think) because I ran out of time to release it before Xmas, and that's why the scroller is much more rough and jumpy than I had wanted it to be.

But you're emu does a great job of showing off my poor and rushed coding in it's full glory!

Devilmarkus · « **Reply #292 on:** 22:23, 30 May 11 »

Well I took my infos from this piece of website:
http://www.cpctech.org.uk/docs/cpcplus.html

Sad:
Missing emulation:
- DMA sound
- Accurate!!! + interrupts
- hardware + rasters
- repeating of sprites linewise
- hardware scrolling
And much more...
Working:
- Sprites (very simple routine, may not be accurate)
- Line splitting
- + interrupts (perhaps inaccurate but ok for many games)
- Accurate CPR reading

Known bugs:
- A bug in memory emulation, mapping is not correct
- crap code (for all + features)
- ASIC maybe is incomplete, some CPR don't even boot up, but this maybe is because mem.-bug

No CRTC 3 emulation done yet... (I am using CRTC 0 with some patches)

Good work so far!!

Keep in mind: Kevin's infos are very condensed with almost no redundancy. That's ok for someone who has a working knowledge of the CPCs, but hardly a learner's guide to the hardware.

And today I added the next useful internal application to JavaCPC:
I asked McKlain, what could be a useful tool.
His reply: "A way to transfer files from DSK directly to CDT"
Well, I coded this little app. quickly and it works fine.
You just can select the files from DSK in drive 0 in the order you need and write them directly into a CDT file.
Example:
http://cpc-live.com/dsk2cdt/ Don't worry because crap sound. I used tape turbo and I recoded a screen area of 1920x1040 pixels!

(No release yet... Still coding...)

TFM · « **Reply #296 on:** 07:08, 27 June 11 »

Do you have a way to transfer from CDT to DSK too? That would be far more useful!

No... Until I can't extract the files from a CDT its not possible

But one day I'll find a solution

Working on JavaCPC Paint GUI + features:
- Adding real Zoom-functionality:
http://cpc-live.com/painttest/

When Paint is finished, and also a bug in Z80 assembler is removed, I'll roll out a new official release!
(Without + Emulation then! Because it's still too buggy)

Congratulations ! There is lots of work involved here.

I've been testing JavaCPC (6.7) lately on Mac OSX (Snow Leopard), works quite well. It has shown an extremely nice - and feature packed - emulator so far.

I guess the only reason the readme.txt mentions 'Windows PC' in the requirements it the two .exe files in the tools folder? Is the jar on SourceForge current?

I did have some smaller freezes / lockups when loading a tape directly from a .WAV which got generated and regenerated from another program (I'm currently doing a Python port of the TZX2Wav C++ utility, a bit like the CDT2WAV Java version).
