Well fine I can do CD too.
How does a console even tell if it was burned?
it can!
it scans track 1 if no track 1 is found then it does not boot the disk as a normal original game!
track 1 contains information like regional protection and boot code and TOC data for the original game if its not found it fails!
no public available cd burners can read nor write this elusive track 1
on a commercial scale this track is pressed into the disk at the factory (some times called disk stamping) it does not use a burner at all!
the ps1 mod chip injects this information and the regional protection/TOC data into the ps1 over and over and over until it boots the disk thus fooling it into thinking its booting an original!
the swap method reads the information off the swap disk or the original disk swapping for the backup mid spin also fools the ps1 into thinking the copy/backup is the original game
other protections added later on were libcrypt which again later was discovered to be burned into the disk subchannel data if this was repaired on burning the backup the disk would fail as it saw it as a corrupt!
the workaround for this was to burn and NOT REPAIR THE SUBCHANNEL data thus keeping the Libcrypt data intact and the copy/backup booting!
