Ahhh, one of my favourite Amiga games.
Impressive work!

Awesome! The gx4000 was quite powerful for its age, but very unsuccessful commercially.

Are you sure? From what I saw, it has a Z80 @ 4Mhz and the same PSG as the MSX. Only the video chip seems better.
Since it was released in 1990 I wouldn't call it powerfull for it's age. Maybe at it's pricepoint (99 Pounds) yes, but not for it's age. An Amiga was way more powerfull (and older). And as for consoles, the SNES & Sega Genesis are also about the same age as the GX4000.

Not sure I would agree the video chip is better... 16 colours at 160x200. Only the palette has one additional bit per colour component (4 bits; the V9958 has a 5-bit DAC actually, but unfortunately not exposed in the palette registers). Using magnified sprites for the overlay and screensplits for the depth effect you can get a similar result on V9958 I think.

(Maggoo’s demo made some different choices but still nice to compare.)

best thing for MSX2+ would be a YUV game
that mode can make something beyond amiga

No need to start a flame war: MSX2(+) wins! Smile

Despites its specs (low-cost, 64KB (V)RAM only, AY again), GX4000 is quite powerful as an 8bitter. But it's from 1990! MSX2 is much older and has unarguably better specs. Commercial failure sure! I clearly remember that most of us were going to 16bits at that time. And everyone was laughing at GX4000 as crap. Cheap but crap.

Well, it's just not as crappy as it sounds. With some time and dedication, you could make it look and sound much better. I mean: watch and hear, and take in account it occurs on a 8bit with 64KB (V)RAM only (how much on MSX2?) and (DMA-)AY (no suggested soundcard as for MSX2).

I knew Maggo's demo! impressive considering when it was coded. My own preview from 1992 on stock Amstrad CPC6128 is there.

Agree. I remember seeing an YJK mode puzzle game mockup here a while ago (set in a temple or something?), that looked really nice. M-Kid too.

@Overflow Ha, good to hear it from the expert Smile. Nice demo btw, tho I'm sure I can't appreciate all the details since I'm not aware of the ins and outs of the hardware limitations.

As for colours on V9958, I'm secretly hoping for a hidden bit which unlocks full 15-bit palette... Smile

Well, there is a MSX "demo" version of Shadow of the beast as well:

But I understand that you are also playing a modified .MOD file in your demo, Overflow? Can you explain a bit more on how you've managed to do that and can it be done on a standard MSX as well?
It woul be cool to have a MSX2+ version of this game with similar music :)

Short story.
Every played note from any instrument is generated as a 4-bit sample @15.6Khz ready to be played on a channel by AY -> 368KB are required on that 512KB cartridge... Note: MOD is 4 voices -> drum-voice & "big fat sound"-voice are mixed and saved as single 1-voice samples. To play those samples on GX4000: 1/3 of cputime is spend to copy 312*3 bytes from rom to ram at each 50Hz frame -> once done, they are sent to 3-channel AY thru DMA at no (cpu-)cost. MSX do not have DMA for AY, so forget it. That said, you guys have another obvious way: use one of your great soundcards.
