GxGeo
What it is
GxGeo is a free emulator for Neo-Geo AES and MVS games, ported from the open-source GnGeo project. It is listed for Wii, vWii mode on Wii U, and Wii Mini, and its license is GPLv2. The project is described as an early version with some bugs. ROMs larger than 25 MB will not work because of memory limitations, although some can be modified to run. Installation uses an SD card: extract the ZIP, then place zipped ROMs and BIOS files in /sd/gxgeo/roms. The instructions name 000-lo.lo and sfix.sfx as required BIOS files and also describe country and system BIOS files; uni-bios.rom can replace a country or system file. Play is supported with a GameCube controller or Wii Remote. A GameCube controller in port 1 takes priority for player 1, with the Wiimote controlling player 2. Downloads are linked through Google Code, Homebrew Browser, and Open Shop Channel; the latter lists a 20101119 release.
