My original IO board did not support one key when playing kof13, so I want to try another IO board. How about this one in the picture? Has it ever been used?Does this support six buttons well?
This is a great Sega I/O for the X2, I've described exactly how I wired up 6 buttons a few posts down in the thread below (there's even a diagram). Could be helpful if you're unsure. Make sure the jumper ("JP1") is in position A to get the 6th button on header.
