Harry Potter Games on PS2

I just want to bring this up from finding this out from experiencing it just recently, do not download the Harry potter ISO games for any of the PS2 Emulators, don't know what one you might be using but I had them on the PCSX2 which is the one I am using, and they caused the entire Emulator to become buggy and unplayable, I had to completely delete the Emulator and reinstall it just to get the other games to run as per normal.
