Sonic World R4 DLC

I am working on a DLC for Sonic World R4 using 2 of Ozcrash's Stages from BSHeroes, Crisis City and Ocean Palace. Those 2 stages are finished with one problem, How do you change the camera angle to make as a 2.5D Look? I tried everything even to code it, it is 3D no matter what I do.

Anyways if you don't know what I mean I might post a video on this website. But you might have to download it from 4Shared
