In the US, the Sega Genesis and Super Nintendo Entertainment System's final official releases in the 1990's were the same game: a port of the original arcade Frogger made to coincide with the PlayStation and PC reboot.
An unfinished game called Frogger 2 was originally going to come out for the Nintendo 64 that was never released to the public. A prototype build was later released by Team CARROT on October 23, 2005. It includes two levels, a port of the original arcade version, and a set of development tools. The port is also completely devoid of sound.
