FileForums - imbnes problems

I am having some trouble with imbnes. I downloaded a bunch of nes roms and tested them out on an emulator and they all worked fine. Then I opened up the rombank and loaded all the roms, removing the ones that arent supported by clicking the corresponding button. After that i created the ISO file and burned it to a cd using Nero Burning Rom. Then I went to play it in my PS2, and half of the roms were all gitchy or didnt even load at all. I even tried them on my PS1 and it does the same thing. They all worked on the NES Emulator that I got, but they dont all work on the PS1/PS2. Some of them work great with no problems, but most of them either dont load, or are all glitchy when I boot them up.

Can anyone help me ?
