By the way, I just tried some of the new stages. Really nice job on Lavender Town! I'll probably port the moving Gastly/Haunter platforms to my "original" version of the stage.
I never thought moving a stage from one stage slot to another would change how the camera behaves, but I suppose it's possible.
By the way, the version of Brawl- 3.5 I downloaded doesn't have STGCUSTOMs in it. Is there a different version that does?
