A differently expanded version of "Jet Set Willy" was released for the Dragon 32/64, with extra rooms. This version could also not be completed as it was impossible to traverse "The Drive" in a right-to-left direction, which was necessary to return to bed after collecting all the items. The game could, however, be completed using a built-in cheat, accessed by holding down the keys M, A and X simultaneously, allowing you to start Willy from any position on any screen, using the arrow keys and spacebar.
