I have the Japanese NES game but I don't have a Japanese NES... only the PAL NES released here. I forget what it's called but it has Ultra Magnus on the label. You can watch the entire game on YouTube actually.

I also have the C64 game on tape, which was so fustrating in it's day

My fave is WFC...sorry, Cybertron Adventures on Wii.

I have to say I like Cybertron Adventures the best, mainly as I seem to always lack time for games. It's good for a quick blast every now and then, so it's problems don't really bother me.
