Well anyway, I came across this thread where I found something that got me very curious:
Specifically, I was surprised to read that you can get 4 PCM channels out of the Genny. I thought that was impossible with ordinary hardware, because I know the console only has 1 channel capable of playing samples, which is what I thought PCM was all about. Then I remembered that I don't know anything about how audio works.Stef wrote:With SGDK you have different possibilities to have music & SFX in your game :
- Echo sound driver
- VGM sound driver
- XGM sound driver
- 2/4 PCM channels sound driver.
I recommend you the XGM sound driver as it's able to play .VGM file (as the VGM driver) while allowing 4 PCM channels (you can reserve 3 of them for SFX).
So the question is: Is it possible to get simultaneous / polyphonic playback of two or more samples out of the Genesis using only YM2612 + PSG, with no add-ons (such as the Sega CD)? If so, would someone be so kind as to explain how this works? If you know of any games or demos that actually demonstrate this use of simultaneous samples, that'd be awesome too!
