Proto:Teenage Mutant Ninja Turtles (NES)
This page details one or more prototype versions of Teenage Mutant Ninja Turtles (NES).
The US prototype of Teenage Mutant Ninja Turtles was found on a Famicom cartridge, in the possession of a former Sunsoft of America employee. Stranger things have happened.
It appears to be identical to the final release, save for the addition of a simple level select screen.
At the title screen, hold A and press Start to access the level select. 1 through 5 start you on the respective level's overworld, while 6 places you inside the Technodrome.
