A few months back, I got Shaymin and Darkrai in Pokemon Pearl using the tweaking glitch. All ended okay.
However, I remember in the tutorial there was a thing about a halfway point, where if you re-entre the Pokemon Centre and go on the upper floor, it'll reposition you into the void (it had a name, but I forget).
Basically, I can't trade Pokemon anymore because it pushes me out of the walls.
More specifically, when I go up the stairs, it thinks I'm coming out of the Union Room and pushes my character off the screen.
Does anyone know how I can undo the tweaking save spot?
