I've made several posts about how great MAME is. For those of you not in the know, it's a program that emulates over 3,000 arcade games, allowing you to play them on your PC. I just found out that in the latest version (.62), there is support for the Bradley Trainer that was made for the U.S. Army from the game Battlezone. The page has a bunch of screenshots, as well as the ROM binaries that are required for MAME to run the game.
