[HELP] JAM files

[Xiron]

It's hard to say what those are from just looking at them, they could very well be packages/archives of stuff that make up the level inside them, or it could be just level information saying what goes where in the levels, who knows. The only way to get at em that way is to have a program made that can either open or extract them. I don't think anyone here is going to make a program for that, sorry.
