Sega Pico is Sega's toy with hardware similar to Genesis/MegaDrive. Recently some prototype ROMs appeared for it, and I've done some work on emulating them. The result is this... little document and this... little emulator. 





What I have problems with is figuring out what kind of PCM format Pico is using. Some raw samples can be found here..., here... and here.... Also they can be easily extracted from ROMs themselves (they are raw data chunks, copied by game to sound chip when needed). I thought maybe somebody of you tech people want to check these.
