I think general Scheisser was just a test of Adams resizing program. It doesn't look like it was retouched at all or anything, which could be done easily.

If there is a way to edit a rom of the jaguar version, I would love to! Those are the best weapons and stuff, and I could get all the maps right ect.

Probably, but porting it to a format you could use might be tricky. I'm not making any promises, though...I know there are programs for hacking into SNES Roms and stuff so you can extract the graphics and stuff for certain games, so I imagine it can be done with the Jaguar as well. I don't know what utilities you'd have to use to do that, though.
