Back Ups of PSX Games

[bsfan]

I recently bought a mod chip and I've made a succesful copy of Fifa 2002. I only have 1 cd-rom (my burner) on my comp and I have easy cd creator 5. My prblem is that with 2 games my comp wouldn't let me copy all the files to my hard drive for copying and with Tiger Woods Pga Tour Golf I was allowed to copy all of the files and I burnt it and it doesn't work. Anybody with any info??
