point blank 2 and psx games problem

[neo1indy]

I've followed the tutorial instructions to the letter.The backup cd works fine on the epsxe emulator but not on my ps2. After the intro movie/screen it freezes on the loading screen.Same thing happens with Final Doom.Just a thought but I've noticed that these games(Point Blank 2,Final Doom,One,Tomb Raider have small images on my hard disc.I mean that not all 650 mb of the cd are used.Could the problem be there?
