About

-----



This is a quick windows port of PicoDrive, a Megadrive / Genesis emulator for

handheld devices. It was originally coded having ARM CPU based devices in mind

(most work was done on GP2X version), but there is also a PSP port.



The reason I'm sometimes doing windows versions is to show certain emulation

possibilities, first release was to demonstrate SVP emulation (Virtua Racing),

later Pico toy and X-Men 32X prototype. It is not to compete with other

emulators like Kega Fusion and the likes.

Vast majority of code written by notaz (notasasatgmailcom).



A lot of work on making SVP emulation happen was done by Tasco Deluxe, my

stuff is a continuation of his. Pierpaolo Prazzoli's information and his

SSP1610 disassembler in MAME code helped a lot too.



The original PicoDrive was written by fDave from finalburn.com



This PicoDrive version uses bits and pieces of from other projects:



68k: FAME/C core, by Chui and Stéphane Dallongeville (as C68K).

z80: CZ80 by Stéphane Dallongeville and modified by NJ.

YM2612, SN76496 and SH2 cores: MAME devs.

Pierpaolo Prazzoli, Rokas, Steve Snake, Tasco Deluxe.



Greets to all the sceners and emu authors out there!
