I finally got around to setting up my arcade, and I have an iPac-mini wired up and in keyboard mode. In this mode, the player 2 button is mapped to '2'. I verified this by plugging my controller into my laptop. I followed the directions here: viewtopic.php?t=448 and set the jamma_vid and pid for my controller. The device now shows up as a joystick and I mapped P1 keys. Player two joystick is able to navigate through the menus just fine. When I go to play games (so far, PacMan, and Donkey Kong), I cannot map the 2P button. It just doesn't register. However, I can use it to start in 1 player mode when the game starts up. Is there a way to make the 2P button (mapped to 2) actually work for these games?
Thansk,
