Do DVD games need to be patched?

[Gurm]

If you have to "patch" your PSX/PS2 cd backups before they work, AND you have a MOD chip... then I dunno what to tell you.

There is no patching necessary at all unless you want a trainer or PAL->NTSC or something.

Or is this on the machine where you're using the GameShark and no MOD?
