is it possible to create selfbootable psx backups? and does any1 know if matafy's way to make self boot backups works? here is how he says to make selfboot psx backups. http://www.cdrom-guide.com/forums/showthread.php?s=&threadid=36305&highlight=boot

No.

It is not possible. The boot sectors of PSX games are pressed into the disc and CAN NOT be written by a CD Wirter.

only if you have access to a cd-pressing machine
