Yes!! Cyclone runs great on the GP32 (132Mhz)

smf is right about the sound, there is no public Z80 core I know of, but at least you'll be off to a start

Please try porting PicoDrive, it designed to be as portable as possible and that would great to see how it runs on Palm.

You can get the latest source on my website: www.finalburn.com/cyclone/

It should port straight over if you are using GCC, just get Cyclone.o, compile the Pico\ directory, and then make an interface for it (e.g. TreoDrive).

In your interface you call PicoInit(), PicoCartInsert() with the rom image, and then setup PicoScan (a function which is called with the pixels for each scanline). Then repeatedly called PicoFrame and PicoScan gets called 224 times a frame with your pixels.

Voila! Plus if you can manage to do a Zodiac one at the same time Prophet will love you forever...

Probably... plus I think I'll scream if someone does another port of PocketSNES running at 15fps and then declares their SNES emulator 'done' :P

You learn something old everyday...
