There is also a patch for the ROMS at

There are a couple threads on here about getting a S&T working in a UDOT. Luckily I didn't have to since it was already done before I got the game. But the directions are thorough and clear. You won't need to hack any wiring if you use it with a switcher. Thanks to some help from don1400, I'm working on getting the setup to work with the -5V EDOT board (eliminating the switcher and hopefully the hum), I just need to order the connector parts. If my plans are correct, you'll only need to either wiretap 2 wires or connect 2 sets of 2 wires to single pin on the MCR power board, so not really much work. You can make the install look quite clean.
