an intresting notion, there is a possibility of putting TMNT IV on Gameboy advanced But it is preety slim, GBA is aimed towards todays kids, not we old timers Most people who play F-Zero on the GBA probebly don't know it was a SNES game and even before that there was F-1 for the NES. Sadly I don't think currently there is a big audience for ninja turtle games. And those who would want it (like the people here) would probebly just download the rom

Maybe when the new cartoon starts up and the movie is out there will be TMNT games, depending on thier sucsess.
