the language you used is somewhat confusing...so i am not sure what you are trying to say....
Modded ps2 play backups.
A hot swap on a retail ps3 will get a 1:1 ps2 backup running.
Patching a disc to master is for test ps2's and ps2 games on test ps3's.
A master disc will not run on an unmodded retail ps2 or ps3..
Do you understand tato??? i dont think i can make it much clearer...
If you have a debugging station there is a disc patcher out there or it can be done in a hex editor if you prefer. But this is not some magical solution for retail consoles to play backups, it is a feature for developers to test their games on "testing" hardware. It is comparable to how ps3 images must be signed for debug use, only much less technical.
