I started my arcade cabinet last summer and because of many things have put it off until now. I ordered the keyboard encoder and before I left I wired it up and tested it on my computer, where it worked perfectly. I then booted up my arcade and then switched the keyboard with the encoder and it froze up the system. If I try to boot with it, neither the mouse nor the keyboard encoder work. I then took the keywiz and hooked it up to my computer where I was able to program it. I even tried plugging it into the arcade without any of the inputs and it still froze the computer up.
