Problem with PCSX2 (and maybe Emuhaste)

I've been using PCSX2 and Emuhaste to try and find some UCM adresses the last couple of days. Recently PCSX2 has begun to run my games strangely, not just KH2FM which I've been using Emuhaste on, but also other games. It's doing strange graphical glitches it's never done before (if I enter the pause menu, it flashes back and forth between the menu and thegame field), it doesn't do the "fade to black"-thing when I exit an area, and it runs a lot slower than usual. I haven't changed any settings with the plugins, so I doubt it's them. I also tried using a different BIOS, but it still glitched out.

Anyone who knows what the problem is? I'm thinking it probably has something to do with Emuhaste, but shouldn't all the changes made in it disappear once both programs have been closed?

EDIT: I think it's something that's been corrupted, either my ISO, savegame, or something about the emulator. I have normally collected all the puzzle pieces, but suddenly there was one...

EDIT: Nevermind. I solved the problem by resetting all my PCSX2 settings. You can lock this if you want.
