Didn't feel like readin' through all the posts, but I figured I'd throw this in. You boot backup ps1 games on a ps1 without a modchip, or a boot disk perse. You just need a real game, and the backup, as well as something to hold the pin down while you have the top of the PS1 open. I forget the exact swap method, but you swap from game, to backup, to game, then backup and it loads. I used to have a friend that could pull it off every time. I never got it to work once. lol. At first, I thought he was fulla BS and had a chip or somethin', but he did it on mine, so I know it works.
edited - found the info.
"Some PSX have a BIOS installed which prevents playback of importgames. (f.e.: a PAL-game on a NTSC-PSX) To bypass this problem you start with an original disk (with the lid open and the door button pressed) until the black SONY-logo appears. Then you have to remove the disk (while it is rotating) and put in the import (or the backup of the import). Now you can close the lid and start playing."
This is the boot method. Just use a backup in place of the import. It may take a few tries. I never really messed with it that much, as I had a game enhancer. But I had a friend that was able to get it to work every time without fail.
