playstation game back up

[Capcom Man]

It's been a while since I did this but, how can I make a working iso by taking the files from a playstation CD?

I used to use mkisofs but I can remember every step I took to make the iso. I copied the files with iso buster, then copied the LBA values to a file, converted that file to a sort file usingg f2s, then burned it using cdrecord. The game boots but it shows a messed up psx logo, then appears to start but all I get it a bunch of garbage on the screen. I seem to be missing something but I can't remember what.

I don't want to make a direct copy of my disc. I want to know how to reconstruct an image of the CD in an iso format (bin/cue is not gonna cut it for me).

Anyone know or is there a better way to make a bootable iso by copying the files off the CD?
