NEO.emu

Advanced open-source Neogeo arcade and home system emulator based on Gngeo 0.8-svn, designed and tested on the original Droid/Milestone, Xoom, Galaxy S2, Nexus 7, NVidia Shield, Xperia Tablet Z, and Xperia Play, but works on many devices with similar specs (performance is very fast and even works well on older ARMv6-based devices). It requires user-supplied romsets from MAME 0.144 or newer for correct operation (neogeo.zip, etc). View the full compatibility list here:
