Then I guess you should take a look at the objects that control the camera and/or the background, assuming they do exist.

GateteVerde might know what to do. And he might even know where to find the original scrolling object. I'm sorry to bring you into this, but I know you've made a Super Mario All-Stars SMB1 engine for both Game Maker 8/8.1 and Game Maker Studio 1.4 and I thought you would be able to help.
