"Bio Force Ape was first revealed to the North American gaming press at the Consumer Electronics Show in June of 1991. Many NES owners first became acquainted with the title in August, when it was featured in a brief Nintendo Power preview. Promising that a release was "just around the corner," Nintendo detailed a game starring a mild-mannered chimpanzee who suddenly found himself in possession of superprimate strength. Being a fan of professional wrestling, the "practically indestructible" ape took out foes using suplexes and piledrivers."
This game never saw an official release. It's multi-region. You can switch between NTSC and PAL by putting the cartridge in the console, turning the power on and then press the reset button 4 - 8 times.
