I have plans to build a full size cabinet at some point in the near future, but for now I have decided to build something small just for fun (and it's cold outside). I have always had a soft spot for the Neo Geo hardware. From playing the original MVS machines and drooling over the unaffordable AES system back in the early 90's. I have been playing around a bit with Arduino and the Raspberry Pi and was inspired by a few other projects I've seen to build a small scale MVS cabinet. I have assembled nearly all of the required parts, including an almost impossible search for a very small 8 way joystick, and hope to complete the project with a very small machine instantly recognizable Neo Geo MVS cabinet. I realize this may not be the most playable machine, but it's just for fun.
I have had a good result running the Neo Geo roms on the FBA version included in PiMAME (pimame.org). The system will run on Micro USB 5v. It has a 3.5 inch screen. Typical controls and layout for MVS (only 1 player) and with any luck will have a somewhat functional 7 segment LED credit counter in the CP.
I have amassed most of the items needed for the build and have built a mock-up out of foam core, next step is construction out of 3/16 plywood.
