GnGeo – portable NeoGeo emulator

Last Updated on July 11, 2021

GnGeo is a software emulator for the Neo-Geo game platform.

It is notable for the fact that it uses specialized cores to emulate the main processors, giving it a significant performance boost over more general emulators such as MAME. Specifically, it uses the 68k core, Starscream 680×0 emulation library, Cyclone 680×0 core, Raze Z80 emulator, Z80 Mame core, DrZ80 core, and YM2610 Mame core.

There are three main frontends available for GnGeo: GGF (Java based), XGngeo (GTK2_, and gngeogui (written in Perl).

Features include:

• Relatively fast emulation (PII 300MHz is sufficient in most cases).
• Emulate arcade and home system.
• Raster effect support (used in Super side kick 2,3,4 and some other games).
• Nebula/Kawaks transparency pack support.
• Interpolation between frame (smoother animation).
• Soft, OpenGL and YUV blitters.
• Many different effects (scanline, scale2x etc).
• Save state.
