This is a modification of the original Acorn Electron version of Aardvark Software's Frak! This hack from 1989 gives the player many ways to cheat. The cheats come from the commercially released disc Cheat It Again Joe 4, sold by Zentrix Software. (The first three Cheat It Again Joe cheat compilations were published by Impact Software.) All the Cheat It Again Joe tapes and discs were the brainchildren of Mark Gidley.
