There was also a 52-in-1 cartridge which my mother got a hold of in the Canadian blackmarket (with the help of my morally-lax aunt). It contained such gems as Circus Trooper, Popeye, and Tank Fighter. It also contained various games that were obviously abandoned halfway into their production, such as "RG Fighter" which is a continous loop of enemies coming in from off the screen and fighting you. There were also a few genuine Japanese creations, by genuine I mean all text was in Japanese. Most of the games would never stand on their own, but filling a cartridge with these games was a fantastic way to waste my childhood. I spent many hours trying to decipher the controls to the "Flying Bug of Freedom." For this deviously enjoyable creation, I thank the Nintendo bootleggers of the 80's.
