The source code, originally based on Genesis Plus 1.2.a by Charles MacDonald, has been heavily modified, with respect to initial goals and design, in order to improve accuracy of emulation, implementing new features and adding support for new peripherals, cartridges & systems hardware. This is an enhanced port of Genesis Plus, an open-source & portable Sega Mega Drive / Genesis emulator, now also emulating SG-1000, Master System, Game Gear and Sega/Mega CD on Gamecube and Wii, through libogc & devkitPPC.
