CPS3 Sound

No real progress on the Backgrounds / Sprites / Palette i’m afraid. Lots of things have been ruled out, but no conclusions have been made on how it actually gets/decode the data from FlashRoms into RAM yet, it seems to be some kind of external DMA but we can’t find any parameters or what triggers it right now.

 

On the good side of things, Eeprom access has been fixed, so SFIII / 2 / 3 boot without Eeprom hacks. Warzard still doesn’t boot for some reason, although ElSemi has it booting outside of MAME (it doesn’t reveal any more clues about the backgrounds/sprites work tho)

 

Also, and this is the main thing I want report here, Phil Bennett has added preliminary sound emulation (as mentioned in the comments of the previous post)

 

Here is a short OGG recorded from SF3 in MAME. As you can hear, the game is running even if you can’t really see anything apart from the health bars.
