BAT BOYS members were Batman, Joker, and Dad ST. Dad was recruted to program softwares menus for the cracked games compilations made by Batman and Joker.

The group existed from 1989 to 1990, then renamed to Alien Nation. Storing several games (each game used 1 disk) onto only 1 disk was a way to spare floppy disks. This was made possible (automatic decompression once the game loaded) by the pirate software "Automation Packer". A new member (Axiom) entered in Alien Nation, then the name changed to IMPACT.
