have a real weird problem. I bought a Messiah2 1.3 and had a friend install it. I noticed that PSone games are now flickery as hell when they were perfect before.
However, if I pop in an original PSone game I have, the flickering problem is gone. I tried different media and everything, as well as messing with options in the PS2 control menu (ie: text filtering and stuff), and it still happens. PS2 backup games are fine (haven't tried CD ROM based PS2 games yet, just DVD).
If anyone can give any insight to this insanely annoying problem I would appreciate it.
