This is a port of Genesis Plus, an open-source & portable Sega Mega Drive / Genesis emulator, originally developed by Charles MacDonald, now running on the Gamecube and Wii through libogc & devkitpro.
Please note that this project is actually more than a simple port and the original core has been slightly modified: with respect to the initial goals, I focused myself on improving the emulator accuracy & compatibility, as well as implementing new useful features and adding support for new peripherals and cartridges hardware.
The result is that Genesis Plus is now extremely close to the real thing, can run the entire Sega Genesis / Mega Drive game library and has nothing to envy to the most popular emulators on the PC platform.
The generic (multi-platform) code is maintained through the SVN repository so that other Genesis Plus ports can take advantage of it, and I hope this emulator can become a reference for open-source and accurate Genesis emulation.
Please read the Wiki or the included User Manual for more informations.
For optimal experience, I'd recommend using these Genesis/SMS adapters made by Raphnet technologies.
If you like this project and would like to support it, you may donate via Paypal. All founds donated will be used to help further development by purchasing equipments such as additional controllers, debugging tools or Genesis development cartridge to run test on real hardware and improve emulator accuracy.
