NeoCDRX
What NeoCDRX is
NeoCDRX, also called NeoCD RX, is a free homebrew emulator for Neo Geo CD and CDZ games on GameCube, Wii and Wii U through Virtual Wii. Players can choose USA, Europe or Japan region settings to access different languages and, in some cases, altered game content. The emulator supports Wii Remote, Wii Remote Plus, Wii Remote with Nunchuk, and GameCube controllers. Listed media options include SD/SDHC, USB and DVD, as well as WKF and IDE-EXI V1 for GameCube. Neo Geo CD virtual memory card saves can go to SD or USB, or to a physical GameCube memory card.
The emulator includes Z80 3.6 and M68000 3.3 processor cores and a three-band equalizer for sound effects and music. To prepare games, place each one in its own folder under NeoCDRX/games, with an mp3 subfolder for music tracks. A Neo Geo CD/CDZ BIOS file named NeoCD.bin is also required in NeoCDRX/bios. Wii and Wii U Virtual Wii installations are packaged for Homebrew Channel, and running the Wii version requires a way to run unsigned code. The README describes the project as open source under the GPL, while GitHub lists an LGPL-2.1 license. The repository is owned by GitHub user niuus and identifies v1.0.02, dated 20230403, as its latest release.
