All three games are Nighthawk, so they are PCs and don't get power from the Jamma connector (each has its own Power supply. Only the 6 in 1 switcher is powered from the Jamma, so the "cheap-o" jamma extenders work great. I'm running the 12 and 5V lines off of the I/O connector from the Silver Strike. Two problems. 1. The switcher doesn't transmit the test button signal. 2. Even though the ad says that the switcher cuts signal to the board, it doesn't. When you are playing another game, all the button inputs are transmitted to the other games. Oh, and I made a 4 into one trackball harness (I'm going to add Golden Tee complete or Live) So all of the trackball inputs are shared between the games too, which isn't really a problem.
