I've got MAME up and running on my system with mini-pac connected to a trackball and buttons. It works nicely, but I'd love to be able to run a second set of inputs at the same time so that I can close the box and still get into the command line to configure other stuff as I add to the system. Adafruit's wireless keyboard and mouse combo (http://www.adafruit.com/products/1738) works nicely, but to use it I need to keep swapping them with the mini-pac. Someone else has to have already done this, but I haven't find a post about the topic anywhere. Anyone know how to do this?
