whats that?[/quote]
(The explanation for the PS1 (PSX) is the same as for the PS2, so I'll say PS1. 'Cuz I'm special.)
When the PSX boots up, it checks for certain things (protections) present on the CD:
- The country code (i.e., PAL, NTSC)
- The presence of erronous sectors.
If either of these are missing, then the PSX won't boot. Okay, the primitive PS1 allows you to do a 'swap trick', and the PS2 version is just a tiny bit harder, but then you end up with the file table of the real CD you use, and so stuff happens bad... meh
Country code = Quite easy to break. No, really, really easy. Just change a couple of numbers on a certain place on the CD.
Erronous sectors = Erronous sectors are basically bad, unreadable sectors of the CD. Special Sony CD & DVD writers used for burning PSX & PS2 games have the ability to make 'bad' sectors.
Problem is, every other drive in the world doesn't.
So the PSX checks if it can read a few certain sectors, and if it can, then it refuses to boot.
While ripping a PSX game, your CD/DVD drive will tell the computer about an erronous sector, and this is just ignored by the software (in the file it's just set to 00), or, if your ripper is advanced enough it may write erronous information into the file.
But if you try and burn the ripped game, your CD recording program will either turn this into valid data (yep, another '00'), or try to send the data to the CD-RW, and the drive will complain and the program will probably crash.
And if it's been written into the file as 00, the CD-RW program just burns that 00. So when you stick it in the PSX, it sees readable sectors where they should be unreadable and doesn't start the game.
