This wrapper makes PicoDrive API-compatible with libretro, thus allowing its
use with libretro frontends, such as RetroArch.
This is yet another Megadrive / Genesis / Sega CD / Mega CD emulator, which was
written having ARM-based handheld devices in mind (such as PDAs, smartphones
and handheld consoles like GP2X of course). The critical parts (renderer, 68K
and Z80 cpu interpreters) and some other random code is written in ARM asm,
other code is C. The base code originates from Dave's (fdave, finalburn)
PicoDrive 0.30 for Pocket PC. The Sega/Mega CD code is roughly based on
Stéphane Dallongeville's Gens.
