It wont flip the screen for the mirror though, so it will be upside down, but for
just testing out a board to see if it might work it can be done. I made some
prototype adapters with the flip circuit, the inputs swapped, and a circuit
to match the audio impedance. Its totally plug and play. At some point
I may make a production run of them. A pic is at the top of my poor mans

Thats what I'm currently running my own deluxe cabinet.
I'm slowly shipping a multikit or two each week, but it seems I'm not having
much luck as the people that have gotten them have had other life issues
come up and not had a chance to test the multigame much. Thanks to Sam
though for hooking his up right away and reporting some issues, of course
that just means more work for me to fix it.
