Play PS3 Backups from a DVD-R / BD-R

Jamal94 knows, and if you don’t, he’s gonna tell you: you can burn PS3 backups to a DVD-R or BD-R (dual-layer media doesn’t work) should the game fit. But now you’re probably wondering, why would I want to do that, Jamal? I got a 500+ GB drive for backing up games. Well take a look here and you’ll notice more than a few games have issues. Reports are coming in that games with problems *may* see improved compatibility when playing from an optical disc. It’s simple really:

1. Backup your [legitimately owned] game to the HDD using Backup Manager.
2. If you’ve backed up to an external FAT32 formatted drive:
   • Connect the drive to your PC and browse to X:\GAMEZ\
3. If you’ve backed up to the internal HDD:
   • Connect to your PS3 with PS3 FTP Server
   • Browse to /dev_hdd0/game/LAUN12345/GAMEZ/
4. You should see 2 directories: PS3_GAME & PS3_UPDATE — and 1 file: PS3_DISC.sfb
5. Burn those 2 directories and 1 file to a single layer DVD-R or BD-R.
6. Delete the game off your HDD.
7. JailBreak your PS3, insert the disc, load Backup Manager and load your game.
8. Store your original game disc for safekeeping.
