GnGeoX is a fork of GnGeo that aims to modernize this great emulator yet giving it a new refresh. It is not the only one, i hope it will be for some interrest. It has also an educationnal purpose : For me at first, to learn about Neo Geo software and hardware, but also, document all what is known to date about this piece of gaming history. Thanks to all those fantastic people who contributed (directly or indirectly) by their work, dedication and generosity, at making this project possible. I tried to credit all ressources used in this project, do not hesitate to inform me if i forgot about someone. I hope it will be useful, feel free to contribute and share.

For hardware accelerated blitters.

GnGeoX uses codeblocks workspace and project files to build binaries.

All configuration can be done in gngeox.ini, please refer to this file for further details, as it is well commented. Every option is also accessible on the command line.

You can start a game with the folowing command:

gngeo -f game or > gngeo --gamename game where game is the name of the rom zip file, for example mslug for Metal Slug

Gngeo is build arround many different block with various license. The original code is released under the GPLV2 with this special exception:

As a special exception, You have the permission to link the code of this program with independent modules,regardless of the license terms of these independent modules, and to copy and distribute the resulting executable under terms of your choice, provided that you also meet, for each linked independent module, the terms and conditions of the license of that module. An independent module is a module which is not derived from or based on Gngeo. If you modify this library, you may extend this exception to your version of the library, but you are not obligated to do so. If you do not wish to do so, delete this exception statement from your version.

Gngeo could not exist without the Mame project, and some code come directly from it (the ym2610 for example). As you may know, the Mame license forbid commercial use, and as a consequence, commercial use of gngeo (as a whole) is also forbided :
