This is an enhanced port of Genesis Plus, an open-source & portable Sega Mega Drive / Genesis emulator, originally developed by Charles MacDonald, now running on Gamecube and Wii through libogc & devkitpro.
The source code, initially based on Genesis Plus 1.3, 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 extra peripherals, cartridges & systems hardware.
The result is that Genesis Plus GX provides very accurate emulation of the systems it supports and has 100% compatibility with Genesis / Mega Drive, Sega/Mega CD, Master System, Game Gear & SG-1000 game libraries (including all unlicensed or pirate known dumps), even supporting backwards compatibility modes when available.
Last but not least, it comes with plenty of exciting features and options that have nothing to envy to your most favorite PC emulators and makes this emulator the most faithful experience for any Sega 8/16-bit fans.
Multi-platform code is maintained through SVN so that other Genesis Plus ports can take advantage of it, as I sincerely hope this emulator can become a reference for open-source and accurate Genesis emulation. If you ported this emulator to other platforms or need help porting it, feel free to contact me.
