Genesis Plus v1.3.1

Genesis Plus emulates a Sega Genesis or Megadrive console. It has been originally written by Charles MacDonald and ported to the Nintendo Gamecube and now the Wii by the “Genesis Plus” Team. It is an open source emulator and a community project which aims to bring you blast processing into the past. Using this “emulator” you will be able to enjoy all of your classic 16bit games in all of their glory. Genesis Plus has been converted from a PC based platform to run on the proprietary PPC Gekko processor and features customized code to give you the best gaming experience possible.

This port is based on Genesis Plus 1.2 source code but has been largely modified to improve overall compatibility, emulation accuracy as well as adding various peripheral supports and interface extra features.
