The Legend of Heroes: Trails in the Sky

[Aerensiniac]

Story in a nutshell:
- Playing Trails in the sky
- accidentally pressing F5 (i think it was F5 at least)
- ever since that moment, transitions on automated camera events (such as entering battle, or cut scene) are blocky and whenever i press start (see attachment) the game's last position is stuck in the background of the menu (it was empty black before)
- Cycling through other F5 render options does nothing, the game is stuck with this crap
- Whenever i enter a battle it annoys the crap out of me, the way it cracks up the screen instead of the fluid animation before i pressed F5.

Any ideas how to get rid of this or what i messed up?

EDIT:
After messing about it for a bit more i came to the conclusion that save states freezed something up.
The solution was to use the game's save itself and then load with the game normally at startup. Whatever was stuck, this reset it. The menu is black again, transitions are finally fine as well...
