What actually happens to the system if Link gets put on a Map coordinate that doesn't exist?
A bit like:
Link is on screen (0,0),
Link->Warp(Game->GetCurDMap(), Game->GetCurScreen()-1);
?
You appear to just be on a completely black screen.
Just wondering how bad this is really, cause I'm getting it quite a lot with my GB sized screens.
EDIT: Oh, I'm not doing this intentionally by the way, just seems to crop up reasonably often.
