We take a look at the 1988 conversion of Double Dragon for the Commodore 64 which is somewhat notorious for poor playability and the infamous "waist gap" the developers issued a veiled apology for in the game manual. We take a look at the "sprite stacking techniques" (aka sprite multiplexing) used in the game - could this be improved on? Is this even what's really wrong with the game?
