Not sure what the problem is, I upgraded to 6.60 PRO-C (Fix 3) from 5.50 GEN D3. Played a few games and they worked. When I try to load Killzone Liberation, my PSP switches off. When I try to load Wipeout, it will load when the orange lines are moving up and down and freeze. Always at the same spot. I tried changing inferno to M-33, same results. Any ideas why this is happening? They worked perfectly fine in GEN D3. My PSP is a slim 2000.
