GnGeo

GnGeo is a free Linux emulator for NeoGeo games. It runs NeoGeo ROM sets identified by their MAME names; the listed command `gngeo mslug` starts Metal Slug. Command-line settings include home, arcade and unibios modes, along with display choices such as fullscreen, scaling, interpolation, raster interrupts, blitters and visual effects. Sound, joystick input, player controls and hotkeys can be configured. Settings can be supplied when launching the emulator or kept in user and per-game configuration files. The project describes graphical frontends, including GGF, XGngeo and gngeogui, with features such as previews and configuration options. GnGeo requires SDL 1.2.x, libz and a NeoGeo BIOS. Games must be ZIP files, while the BIOS must not be, and the default search location is `$prefix/share/gngeo/`. NASM 0.98 is optional for i386 assembly optimization. The README describes building from source with `./configure`, `make` and `make install`. The repository lists no releases. Its license notes say commercial use of GnGeo as a whole is forbidden because of included code and licensing.
