PSX CD backups

[Ulrezaj]

I've got a few questions that I don't think have been covered anywhere here. First off, when one says a "successful burn" of a PSX game, that doesn't necessarily mean a playable one without a mod chip, right? I've used Nero, WinCD and CloneCD and though I burn successful copies, none of them play on my PSOne. So is the only way to make a playable copy, to patch it using PPf-o-matic? Additionally, do you have to patch the protection with the correct region type? ie: Is it possible to use a UK-PAL ppf patch on an NTSC/UC game? And is it possible to use multiple patches on one disk image? Thanks for any help. Just trying to save myself the trouble of getting the Cheat CD or modding my PS.

(why are all the protection patches on this site for PAL only?)
