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.

Special thanks (ideas, valuable information and stuff):

Pierpaolo Prazzoli, Rokas, Steve Snake, Tasco Deluxe.

Greets to all the sceners and emu authors out there!
