Promo items include toy car, notepad and hat. This game was planned to be a 'Batman' license...the police car was to be the Batmobile and the Jail was to be the Bat Cave. Designer Mark Ritchie stated that the art has to be changed at the last minute because Data East, a competitor, already had the license for Data East's 1991 'Batman'. The yellow limousine taxi in the backglass appeared previously on designer Mark Ritchie's game Williams' 1988 'Taxi'. In the Files section are four large zipfiles of pictures of an Engineering Test Game, possibly MEL, having serial number 573 X270006. Also included there is a PDF of a Q&A between the game owner and designer Mark Ritchie about this test game, referencing some of the images contained in the zipfiles.
