I finally finished up the wiring. I also installed a new video card, MAME, GameEx, and several emulators on the PC that will be running the arcade. I may have to make one minor change to the wiring, but for the most part it is working great. Here are several pics. One is of the control panels fully installed. There is another couple of pics which show the wiring for the top and bottom tier. The wiring is definitely not as nice looking as some of the other arcade cabinets I've seen, but it works and that's what counts. Also notice in the pic of the top tier that there are connectors which connect the top to the bottom tier. This is so the top tier can be easily disconnected and a new tier added (perhaps one with positional guns or steering wheels).
