I still have all of the relevent files to this and can remember how I did it.
I could never get the models to work properly. The game is too unstable when putting in custom models.
For a while I had it working but have never been able to get models to work without crashing.
If anyone has a fix for it I'll finish this straight away!
EDIT: I see VC Mobile has been updated this year. I will try and see if I can get stablity with some kind of model. I did try lowering polys and everything but nothing would work. I will update with my progress.
EDIT2: Now think I can get this working just need time.
