NeoCD-Wii
What it is
NeoCD-Wii is a free, open-source Nintendo Wii port of the NEO-CD REDUX GameCube emulator for Neo-Geo CD games. Installation involves extracting the program to an SD card or USB drive and placing game files in folders there. The emulator requires a NeoGeo CD/Z BIOS file named NeoCD.bin inside a BIOS folder at the SD card root. Game audio tracks are supplied as MP3 files in each game’s MP3 directory, using Trackxx.mp3 names; 44.1 or 48 kHz and 128 kbps or better are recommended. Version 0.5 lists interlaced and progressive video modes, a filter toggle, configurable Wiimote and Classic Controller buttons, saved settings, and page-based game browsing. The port supports the Wii’s internal SD slot and is libfat compatible. USB 2 support requires IOS 202. The project is distributed through GitHub and the Open Shop Channel, under a GPL-3.0 license. Version history notes that some games may still show black screens or graphics bugs, and DVD support was untested.
