First of all - I'm using PSX2PSP to convert game to .PGK file. My console model is CECH-3004A (4.84 HFW). Problem is that games on my PS3 are noticeably slower than should be. I mean - audio is slower as well as whole game. Problem appear anly on NTSC games - PAL version are working fine. Another thing is that I installed Syphon Filter 3 (NTSC-U) on my console, but it didn't appeared in XMB, and I have no idea why.
