GnGeo is a powerfull W.I.P NeoGeo emulation package optimized for Vampire accelerators or V4 standalone. The new release offers Audio optimisation and ASM/AMMX optimisations. The Neo Geo family of hardware began with the Neo Geo Multi Video Systems (MVS) which was released by SNK in 1990s. In the early 1990s, the brand became extremely powerful owing to its incredibly powerful specs and high quality titles. a series of home console versions of Neo Geo hardware were released starting with the Neo Geo AES which was originally intended for commercial use, but later became popular enough to warrant a release as a home console. This was then followed by release of the Neo Geo CD in 1994 and the Neo Geo CDZ in 1995.
