    This is yet another Megadrive / Genesis emulator for PSP, but with
    Sega CD / Mega CD support. Although it has been originally written having
    ARM CPU based devices in mind, it has now been ported to PSP too, by
    replacing ARM specific parts with portable C code.
    The base code originates from Dave's (fdave, finalburn) PicoDrive 0.30 for
    Pocket PC. The Sega/Mega CD code is roughly based on Stephane Dallongeville's
    Gens.
