I'm not gonna bother with that really, coz then I'd have to make more changes to it than before. I'd have to make it a separate model, then i'd have to go through all the levels and change it so that it loads that model, as well as add loads of IF statements to the areas in disc 1 so that it loads the new model on disc 2+3, but not disc 1. I don't think it's worth it really.
Besides, I have other plans in mind...
