Yes, and here's a video I just made for you to see and hear.Quote:

I'm pretty sure that samples on the Master System requires the Z80 as well the PSG.
Well yea, how else would it play it? The only CPU in the MS is the Z80 and the only sound chip is the TI PSG chip.
You don't get any advantage in using the PSG for sound effects vs mixing them to the DAC. It's far less efficient to do PCM on the PSG. Maybe the timing is easier? I dunno.
There is no advantage, it was used on SMS as there is no other way and to do it on MD is waste of CPU power.
Would all the resources required, explain why the picture freezes and the controller freezes during sample playback?
That is a lot of resources, lol.
I'm pretty sure other Master System games play samples without freezing the screen. I guess they might be cleverly hidden in static screens though.
I'm not sure about Toy Story. It uses an XM player for the PSG channels though.
Also about the PSG, samples can be used, but as TmEE said, it's pointless. After Burner II (MD) uses PSG drum samples for whatever reason for example. I also think Street Fighter II also uses the PSG for Voice samples, which is why both of those games sound horrible.
The freezing happens because you need all of the CPU power for "good" playback. On MD you have Z80 just for that so 68K can do whatever in wants.
I was talking about the Neo Geo you ninny! Price doesn't matter. Are you a wiener or a real hot dog?Quote:

After Burner 2 does it but sound quite bad imo. Street Fighter 2 use the DAC and is only able to play 2 PCM at once with very bad quality due to the large DMA done.
Actually we can easily saw this game is poorly programmed in some way... it sometime transfer up to 3 times the same part of VRAM in a single frame which is definitely a program design problem. Too bad because that really hurt on PCM playback.
About PCM on Master System, is there any Horizontal interrupt on this system (i am a total SMS newb) ? if not then i do not see how you can do PCM playback without freezing animation, i would hardly imagine interlacing game code with PCM playback code as we can do on MD Z80.
It seems Capcom didn't program anything very well on MD, especially DAC or FM in general. They could have done a much better job at probably every single game they made on MD, and even SNES as well (thinking of Megaman X2 in particular, because of constant, massive slowdown littered throughout the game).
There is Hint, but you will spend big chunk of the scanline doing the sample, it is not so nice...Quote:

At the end of the day when it came to colour and sound samples SEGA Mega Drive wasn't has good as it should have been.Quote:
It's still running on real hardware, and aside from the Wave Playing engine there's nothing preventing any of those homebrew Z80 sound engines from being used in a real game situation.
