Custom stage editor?

[banjo2]

Hi. I was wondering if there is a custom stage editor that allows more then the regular stage editor. Before you suggest the stage studio by Xane, I have already tried that. The reason i'm asking is because I saw "Halfpipe" by heinnerman. The slants are stretched. I opened it with stage studio and barely any parts show up. What tool did he use? I can't find anything about him anywhere. By the way please try not to give me any Smashboards pages because those pages crash my laptop.
