I'm going to look online in a sec but wondered if anyone knew right now. I'm setting up for a private party at 8:30 and can only put on 9 credits on Rampage. Any Help?
If you download the ROM for a newer version of MAME and go to the dipswitch settings, you might get an on-screen graphic of the switch bank, and you can watch the switches move as you toggle the settings. It doesn't work for every ROM, so I can't guarantee it.
