I'm using emuhaste, so I just activate it before going through a door.
I apologise for the 3 year late bump, but from what I've dug around this is the right place to ask it. Do inform me if there was a more proper place to do so. It's about if someone knows a place where you can use the room mod to correctly* enter The Dark Margin (1032BAE0 00000001). sora_101's tip to use the Hall of the Cornerstone did solve the problem for a bunch of rooms (such as Roxas' room and Station of Awakening), but just as the other rooms I've tried, it doesn't work for The Dark Margin. *Correctly as in you can move around normally, and not frozen like in a T-stance. Any tips?
