Damn, my stuffs lost again... >:(
I knew those chickens were useless, I gotta kill'em all...

I suggest that winner games done more work on the game design.
Damn, missed it. Should have sent an email out to users or something :(
Yay, Subtera Puzlo came 3rd in the game category :)
That means a lot to me as I really respect the guys at Push'n'Pop.
Although I expect it's more down to EgoTrip's design than my coding - if anyone there had seen the source code they might have voted differently ;)
We see the result, and we like what we see :)

Never mind, the vote was just about Cyber Huhn, which had only one static level. But Cyber Chicken could not be voted for. Your graphics really rock!!! :) :) :)
Still... must kill all those chickens !!!!
yarg, there are even more, pew pew, die chicken !!!!

Sure. Nobody can see the code. So it's IMHO also pointless to have votes for 'technical achievement' because nobody can know about it - except you start to disassemble it.
Why, can't you judge a technical achievement if you got a title with two bazillion sprites on screen, 100Hz scrolling, continuous sampled soundtrack or a billion different screens all fitting in 16k?
Nonsense - we judge the technical aspect of things from the results all the time.
Well, most of the people obviously judge in the way TotO said. I agree with him.

The code works, the game works, without bugs, that's what matters right? Don't sell yourself short, you did a good job and got it working almost exactly how I wanted it.

It's obvious to anyone even without looking at the code that the Phortem disk loader, for instance, was a great technical achievement. Even those who don't know how hard it is to do anything else whilst loading from disk can appreciate the fact that nobody else has done it before!
you can judge "technical" achievement by the result on screen... if it is badass and well animated, impressive and unseen, then it is such achievement.
But yeah, coders would have a word on this.

that's a clever move...

Obviously? Then you should have voted for it. Because nobody did. It got exactly ZERO voted for technical achievement. And you know what? Of course its an great achievement, but why did nobody vote for it then? Where is that anyone you talk about?
So you prove TotO and me right. Thanks man! :)
I don't remember cyberchicken being an actual choice in the "technical achievement" category... was it ?
Nope. No CyberChicken at all, only CyberHuhn. But doesn't matter, the release before X-mas was probably too short. About the technical achievement it wouldn't matter anyway:
- 360 degrees pixel-precise scrolling (best played with SF2 mouse I guess)
- Highest number of sprites ever seen
- and up to 50 fps while it all happens
- First game supporting CTC-AY
- Non vector GFX in realtime calculated 3D space
Of course this is a bit ahead of time. But things like smooth scrolling in X and Y while using overscan is kinda boring to me now, did that years ago. So why bother about CH, CC or yesterdays snow. :laugh:
I already have a great idea for my next ROM game which will use a kind of scroll never seen before on the CPC. ;) :)

Why? At the time I voted, I must have thought that Still Rising overall was the better technical achievement because it did a lot of things very well. I actually can't remember which I voted for, but if Phortem didn't get any votes I guess I must have gone for Still Rising in the end.
That said, Phortem is a more obviously good technical achievement simply because nobody else has managed to achieve that before.

There is no emoticon for "the finger" so I shall just say: limited time, not skill :p

There is a bug? I didn't notice that one. But still, without Redbox's coding, the CPC version would be nothing more than a figment of my imagination, and DS only.
It's a great job. You need a lynx eye to see it! :D

Both are great productions for sure.

It's that on the horizontal axis the main sprite isn't pre-shifted so the movement is not as smooth as the other sprites. You only really notice it on a real Amstrad monitor.
TotO pointed it out before the competition ended but and I tried to fix it but ran out of time - it would have meant rewriting a lot of the engine as I had made a mistake in the erase/draw routine.
What was strange for me is that I had to go away for the last two weeks of June and had no internet where I was so spent much of that time wondering if EgoTrip or one of the organisers had found a massive bug that I would have no idea about or time to fix...! Luckily it was all okay in the end.

Let's say people have an idea about what CPC is able to do.I find this year technical achievement award was fair, the first two titles mixed nicely hard and software technics, as i saw cc uses nice software technics to get speed and is 3rd.

I'll look forward about this , we need new technics ;)

I must say FDC technics are not so easy to detect but i'd say too two previous titles own already great track loaders (BF & OP), that's why too it seems not so impressive despite the fact it is a great work.About Relentless, we can say dual playfield and R3 scroll are not new but this is the first time they were so well used, that's why it deserves technical achievement for me (i must say first time i saw it i didn't notice on the first look that was dual playfield).Same thing , the game uses a clever way to deal with the 16K limit and dual playfield with 4 colors objects, graphics are very well adapted to this , this is a technical achievement for me too.
Just an "historical" point. We already see trackloaders in:
- The Demo (1991)
- 5KB Demo 3 (?)
- Midline Process (2004)
- Ze Meeting 2003 (?)
- Demoizart (2005)
- Orion Prime (2009)
- Batman Forever (2011)
So we can't say it's new... although Arnoldemu make a good job!
There's a difference between a trackloader and trackloader that continues its effects whilst loading. Most CPC demos pause entirely during disk access. I thought no demos had done this before, but I'm happy to be proven wrong! :)
EDIT: How had I managed to miss Orion Prime? That's awesome! :)
Oh, I think there is a little confusion, Doz.
In Batman Forever and Phortem the schema is diplaying/loading/displaying/loading/etc. So when they load, they "only" play the music, but don't manage anything else: the screen is freezed.
In 5KB Demo 3 (for example), it's more technical since they load, play the music, and manage some splitscreens and scrolls at the same time! In Midline Process, Ze Meeting 2003 and Demoizart, it's the same, and even more: Targhan load, play the song, and display something at the screen. These demo needs "microcoding", i.e. mixing displaying/loading in the same code (to be short) which is more technical than "just" loading and playing the music (there is no mixing: you play, then you load).
One more time, it's not to undervaluing Batman Forever and Phortem trackloader, but it's a "simple" trackload if we compare to 5KB Demo 3, or Targhan's one (Midline Process, Ze Meeting 2003, Demoizart) which are more technical...

That's what I was getting at, as that's what seemed to be happening on Phortem (at least that's how I remembered it). And having just re-watched DemoIzArt, it's definitely doing something during loading, so I guess my bad...

Yes you are correct about the loader in Batman Forever and Phortem.

- "The Demo" has interrupts enabled while it plays. Music is 25Hz playback I think.
Sectors are 256 bytes each, 16 per track I think, and all with the same ID number!
There are many times the FDC produces overrun error, and the loader keeps retrying over and over. This is why it's slow.
It uses 256 byte sectors so it has a chance of loading something within a frame.
At the time it was amazing! Now it's a bit more "brute force" approach. I think the data must load in order. The music player is standard.
- "5kb demo 3" extends this. Interrupts are enabled, 256 bytes per sector. At the start of each sector is a "order" or "chain" information. The data doesn't need to be read in order, it can accept any sector that is successfully read and knows where to position it to make the correct order when loading is complete. I can't remember, but it may re-order the data after load. Don't know about the music player, it may be standard.
- Midline process: Don't know much about it. I know it uses much larger sectors (4K??), coding is probably clever interleaved and synchronised with the loading. I think it's done this way in order that the music can play and the effect can run at the same time as loading.
- Batman Forever uses GAP spacing, and the sector IDs are interleaved so that when it's finished reading one sector, the next one is ready to read almost immediatrely. It's setup so that 1 sector should come every 50hz assuming 300rpm. 512bytes per sector, so it just fits within 1 frame. The interrupts are enabled from when the command is sent to the FDC to when it receives the first byte. The music player is AYC based because it's quicker and means the interrupt doesn't need to be active more than necessary and affect the loading. If there is an error, it compensates a little by playing the music and retrying to try and get the music at 50hz.
I did try another method where I interleaved the AY register writing with loading data, so that the music routine update is seperate from sending registers to AY, but it prooved to be too much of a problem for me at the time so I never completed that method. I have a prototype loader with this in.
The critical part in any loader is when you are reading the sector data from the fdc. More specifically disabled just after the 1st byte. They can be re-enabled before the last byte. At other times the overrun can happen and this stops the fdc from reading any more data and you are forced to retry.
You can just about do away without checking if the fdc has data to read, if the rotation speed is close to 300rpm ideal. In this case a byte comes every 32us which you must read, no errors can happen and you must read all bytes. I have tested this. It's possible to add extra instructions so you don't need to burn cycles waiting for the next byte, as long as your IN to read the data comes at a good time.
You can leave interrupts on during all commands except the reading data part of read data/write data/format/scan.
Also some historical facts, smooth scroll is not new, we saw that before in:
- Tornado low level
- Mission Genocide
- Burnin Wheels
- Edge Grinder
- Star Sabre
and others
CPC demos always focused on hardware, while on other systems demos already did become art. Recently demos on CPC became art and catched up. Maybe it's time for games to do the same. Hardware techniques are nice, but I guess during the last 30 years they have been used enough. Time to add some serisouly smart and funny artistic things which people really give a good feeling while watching / playing. :)

...4D? Wow! :D
No... it's about 2.7 dimensions [nb]4D, 5D, 6D and 7D always totally freaks out humans on this planet. And I got no idea about dimensions above that. But I heart there must be 12.[/nb] ;)
Ah, not impressive then... I guess a bog-standard Z80 can do it hands down.
Haha! I know if 2D is really impressive already how could it be 3D or sphere scrolling.[nb]Love to be ahead of time ;) [/nb] :laugh:
And... Will it be fun to play? :-\
I got no idea... :-X
Quote from: arnoldemu on 18:37, 04 February 14
You can leave interrupts on during all commands except the reading data part of read data/write data/format/scan.
The biggest problem is getting an interrupt either just before the first byte, or between the first byte of the sector and when you disable interrupts which will cause an overrun. If you could get your ISR really short, just decrementing a counter which can be modified during reading, then you might be able to avoid overrun altogether while still counting the number of interrupts which have passed, eg.
0038: DEC HY
EI
RET NZ
...
But it's still necessary to be somewhere near the beginning of the sector on the disc, perhaps using a Read ID to find the previous sector and waiting for a whole sector worth (eg. 256 * 32us) of time before modifiying the counter. eg.
loop: CALL readID
CP prev
JR NZ,loop
CALL wait_sector
DI
LD A,HY
ADD 64
LD HY,A
EI
CALL read_sector
DI
LD A,HY
SUB 64
JR Z,ffb
JP P,no_ffb
ffb: ADD 6
LD HY,A
EI
JP frame_flyback
.no_ffb:
LD HY,A
EI
RET
Sadly I did not vote this year, but I take to congratulate all the winners here.
On the demos category, I think Still Rising and Phortem were the best works.

I do not know if Arnoldemu made some improvement in the loader for Phortem regarding the BF version, but I remember that his loader, in addition to playing music per each frame, had some extra time for some quick effect.
In fact, I can remember I did this in BF, for example, just before the Gotham City 3D, you can see a transition effect with random squares drawing the city sky running simultaneously with the loader + music. I do not remember exactly how much additional time is allowed, but I'd say about 8 scanlines smoothly.
Best about the Arnoldemu loader is its speed, allowing quickly load almost 128kb, which is great for demos.
