Hi all, I’ve been working on a multi build along with a HDMI install inside of a Jasen case for a local collector, and hit a snag with the build. The build was in a perfectly functional state during the build, but had to be assembled and disassembled multiple times to test a handful of...

I have a few unmodified Neo Geo MV1C motherboards left, happy to sell them within the USA for $70 shipped with the plastic shroud or $65 for board only. Boards have all been lightly tested with KoF99 to confirm that there are no issues with the graphics, audio and the I/O for both players...
