I've had bad luck with MiniPac and wanted to try something else. My latest problem was with one key (for joystick) not emitting an auto-repeat. I tried to fiddle with the WinIPac firmware utility program, and got into a state where my board is no longer recognized.
My current arcade is 2P with 22 buttons + 2 joysticks = 30 keys + Happ 3" trackball, all controlled from the MiniPac.
I really like the fact that MiniPac offers a wiring harness for all your keys, and it's very small. Can anyone recommend alternatives for Minipac that can handle my 30 keys (no need for LED lighting)?
