NeoCD-Libretro vs NeoCD/SDL

NeoCD-Libretro has no write-up on Specifiction yet; its figures are above.

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.
