I have an idea for a Remake of Teenage Mutant Ninja Turtles III: The Manhattan Project for SNES, I have always wanted to see this game in 16 bits I don't know why in its launching time it didn't have a port for arcade or Super Nintendo.
The idea would be to have as base the ROM of Turtles in Time, for graphic elements like the turtles and some enemies and objects, I know that this would be a quite complicated project since they would have to recreate the scenarios of TMNT III and several sprites of enemies and bosses that don't appear in TMNT IV, as well as the scenes between levels.
Also this can be applied to another project like the remake of Teenage Mutant Ninja Turtles II: The Arcade Game, a game that was released for NES with some extras that are not in the arcade version, I would also love to see this one in 16 bit for SNES.
These ideas are free and can be executed by anyone who is interested and can make these two projects a reality.
