NeoCD/SDL vs NeoCD-Wii

NeoCD/SDL is a port of the NeoCD NeoGeo CD emulator to the SDL library. It can run many original NeoGeo CD games and is listed for Windows, Linux, BeOS, and Dreamcast; the project also lists ports for Xbox and PlayStation 2. Each of two players can use a keyboard or a separate joystick. Keyboard shortcuts control fullscreen display, video effects, frameskip, sound, screenshots, and quitting. To run the emulator, users need an uncompressed 512kb system ROM named neocd.bin. The documentation says users are not entitled to a copy of the copyrighted BIOS unless they own an original NeoGeo CD console. The emulator and its source code are free, but selling is not allowed, and the emulator cannot be provided on the same physical medium as NeoGeo game software. Source code and technical knowledge may be reused only for non-commercial purposes. Downloads include source and binary files. Windows builds require MinGW, MSYS, SDL development libraries, and NASM; Linux builds require SDL source and NASM. The program is distributed without warranty.

NeoCD-Wii is a free, open-source Nintendo Wii emulator for Neo-Geo CD games and a port of the NEO-CD REDUX GameCube emulator. Installation involves extracting the archive to an SD card or USB drive and placing game files in folders there. USB 2 support requires IOS 202. The emulator also needs a NeoGeo CD/Z BIOS named NeoCD.bin in a BIOS folder at the SD card root. Game audio belongs in each title’s MP3 directory as Trackxx.mp3 files; 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 browsing. The project supports the internal SD slot and is libfat compatible. Some games may still show black screens or graphics bugs, and DVD support was untested. The repository lists GPL-3.0 licensing.
