I have used PCSX2 without any problems before but now Whenever I open PCSX2 0.9.7 my screen changes to a negative-like effect and it gets distorted. The pictures of the normal screen and the problem are below. I would really appreciate it if someone could help.
delete the ini files and try again. It's something that got corrupted, some non normal resolution and so on. Maybe you'll need to reinstall the whole application.
I tried deleting the ini files but it didn't work so I reinstalled like you said but it still didn't work. But the picture is no longer negative. It just has a bad resolution.
