[DTHLongplays]

Hi everyone! I have a problem with Star Wars The Force Unleashed and i need some help to solve it. When i start the game everything seems fine, but when i in game, then screen has red lines on it, which hurts my eyes and makes this game impossible to play. When i first downloaded this game i didn't had this glitch or bug or whatever you gonna call it, but now it's just there and i don't know how to fix it. I tried every setting, but nothing seems to help. So i decided to came here and ask for your help guys. I'm using latest 1.8.0 version of PPSSPP emulator to play PSP games.
