For something like that, I'd probably change the scroll margins. Specifically, ProjectObj.GamePlayer.PlayerSprite.ScrollMarginX, and (possibly) ProjectObj.GamePlayer.PlayerSprite.ScrollMarginY.
Maybe have some code that lets the game know when you've turned around, change the scroll margin, and then set a timer so you know when to change it back? I'll let someone else handle specifics, though, since I've never played the game. But if you can handle some scripting, you might be able to do it yourself...
