So it looks like a Supra but has the specs as the Storm.
No, it's really just an amped up Supra with bad handling, I had some trouble getting it around corners. I was able to race the actual Lister Storm after deactivating one of the codes I originally entered when playing the Demo.
Like I said above in one of my edits: I entered a code to prevent the game from crashing when racing the car, but the code interfered with the Lister's body data and gave me the Supra instead. I tried the same thing with the Vector M12 with the anti-crash code in place and also got a Supra for that. The cars turned back to normal though once I got rid of the anti-crash code.
It was a cool discovery for me though, I wonder if I could get other cars for using different cars that were originally unplayable such as the R33 Skyline or the AMG Mercedes.
EDIT: Actually, I think the Supra did have Lister Storm performance. I may have accidently made one of the first GT2 Demo car hybrids. Xenn, I think the anti car crash code you made works, it just doesn't prevent crashes, but gives different body data for cars instead. I'm going to try to experiment some more. I think I've just about figured everything about the Gran Turismo 2 Pizza Hut Demo. It looks like I have some more videos to record.
EDIT 2: It's confirmed, the anti-crash code Xenn gave me does something else. It allows me to drive the cars that originally crash through car selection, I use the anti-crash code on top of a car body code of a car that's actually driveable in the Demo and then I can drive a car that was originally not driveable.
Here's proof; I'm racing a C43 Merc. on Midfield.
