What makes a Playstation game self-boot?

[VampDude]

according to Wikipedia:

the discs were mastered with a specific wobble in the lead-in area. This wobble encodes a four-character sequence which is checked by the CD-ROM drive's controller chip. The drive will only accept the disc if the code is correct. This string varies depending on the region of the disk—"SCEI" for NTSC:J machines, "SCEA" for NTSC:U/C machines, "SCEE" for PAL machines and "SCEW" for the Net Yaroze. Since the tracking pattern is pressed into the disc at the time of manufacture, this cannot be reproduced on a CD-R recorder.

That's what I thought, that's what makes the discs used for PSone games unique (although it's done with all games on all consoles thesedays).

hey everyone, sorry for the ectremely long absence, however i would like to mention, acording to one user from NGemu, u can do so by backing up a PSX game at one of the slowest speeds with no error correction and reading in Raw mode.

upto now, isnt it possible either way?
