@plgDavid @TheMogMiner I need to look more carefully and thinking I may need to disassemble some of the A'can games to understand better but… are we sure that there's a sound coprocessor at all? (are games loading arbitrary blobs into some RAM or something?)
Additionally, the 68k uploads perfectly valid 6502 code to the shared 64kbyte space. In my local code, the 6502 is now polling inputs and handing them off to the 68k. Further, it's clearly processing what appears to be some kind of note data, and poking SPU registers.

I'm in the process of manually converting the player code to C-like pseudocode to get better insight into exactly how the player program expects the SPU to function.

In general, just saying, many of your tweets at
@plgDavid and I make it sound like you're falling into the same trap that so many others have, which is assuming the MAME team are a bunch of idiots who somehow YOLO'd their way into emulating thousands of systems. - Näytä vastaukset
