GxGeo vs NeoGeo CD Redux

GxGeo is a free Wii-family emulator for Neo-Geo AES and MVS games. It is a port of the open-source GnGeo emulator and is licensed under GPLv2. Supported platforms listed are Wii, vWii mode on Wii U, and Wii Mini. The project is described as an early version with some bugs. ROMs larger than 25 MB do not work because of memory limitations, although some ROMs can be modified to run. Installation requires extracting the ZIP to an SD card and placing zipped ROMs and BIOS files in /sd/gxgeo/roms. The instructions require 000-lo.lo and sfix.sfx, and describe country and system BIOS files; uni-bios.rom can substitute for a country or system file. Play is supported through a GameCube controller or Wii Remote. A GameCube controller in port 1 takes priority for player 1, while the Wiimote controls player 2. Downloads are linked through Google Code, Homebrew Browser, and Open Shop Channel. Open Shop Channel lists version 20101119.

NeoGeo CD Redux is an open-source NeoGeo CD emulator with build targets for Nintendo GameCube and Wii. The Wii target runs natively rather than requiring GameCube mode. It loads game media from SD cards and DVDs, with USB loading on Wii, plus FAT-formatted SD access through WKF and FAT-formatted hard-drive access through IDE-EXI. Wii controller options listed are Wii Remote, Nunchuck, Classic Controller, and GameCube controllers when the stated detection condition is met. Video output includes progressive modes and 480i, 480p, 576i, and 576p, with component-cable detection. MP3 playback from SD and DVD is documented. Save files can use SD storage or a memory card, while WKF and IDE-EXI write support was not included in the listed release. The project lists .bin/.cue, .img, and .iso images. It is free, and the latest changelog entry is unofficial version 0.1.52A.2 from July 18, 2013.
