Problems with backup games...

[n000b]

My first question is do NTSC games work on pal machines? Or doesnt it even start?
My second question is that I have just bought a chip for my ps2 (no solder modchip+actionreplay) And I have got many of my games to work with it but some games like THPS 4 and Smackdown shut your mouth doesnt work (THPS is NTSC and I have pal, but shut your mouth is pal)
And they dont work some one told me that I should use 90min cds but I have tested that too and it doesnt work. I burn my games with Nero. It seems like every game with a bin file over 700mb just doesnt work. Anyone here know what to do? Im still just a noob with these kinda things.
