NeoCDRX
What it is
NeoCDRX is a free homebrew emulator for Neo Geo CD and CDZ games on Nintendo GameCube, Wii, and Wii U through Virtual Wii. It supports USA, Europe, and Japan region settings, which can provide different languages and sometimes changed game content. Supported controllers include Wii Remote, Wii Remote Plus, Wii Remote with Nunchuk, and GameCube controller. Games can be read from SD or SDHC, USB, DVD, and GameCube storage options such as WKF and IDE-EXI V1. Neo Geo CD virtual memory-card saves can go to SD or USB, or to a physical GameCube memory card. Audio includes a three-band equalizer for effects and music, while listed processor cores are Z80 3.6 and M68000 3.3. Setup requires a NeoCD.bin BIOS file and separate game folders with mp3 subfolders. Wii installations use Homebrew Channel packaging and require a way to run unsigned code. The project is associated with GitHub user niuus and lists v1.0.02, dated 20230403, as its latest release.
