What it is
NeoCDRX is a free homebrew emulator for Neo Geo CD and CDZ games on GameCube, Wii and Wii U through Virtual Wii. It supports region settings for USA, Europe and Japan, which provide different languages and can affect some game content. The listed processor cores are Z80 3.6 and M68000 3.3, and audio controls include a three-band equalizer for music and sound effects. Supported controllers include Wii Remote, Wii Remote Plus, Wii Remote with Nunchuk and GameCube controller. Media options include SD/SDHC, USB and DVD, plus GameCube options WKF and IDE-EXI V1. Virtual memory card saves can go to SD or USB, or to a physical GameCube memory card. Setup requires a Neo Geo CD/CDZ BIOS file named NeoCD.bin in NeoCDRX/bios. Each game goes in its own folder under NeoCDRX/games, with an mp3 subfolder for music. Wii and Wii U Virtual Wii installations are packaged for Homebrew Channel; using the Wii version requires a way to run unsigned code. The README describes the project as GPL open source, while GitHub lists LGPL-2.1.
