Wenas a tod@s,
Pues según esta información (yo sigo muchas de las noticias desde esta página porque actualizan la info a una velocidad increible) se puede jugar con backs ups grabados en dvd's...y explica el proceso...
http://psgroove.com/?p=668"Step1: Launch Backup Manager and Backup the original disc to the Ext. HDD
Step2: Plug the Usb HDD to the pc and Browse to “X:/GAMEZ/[title_id] Ex. “G:/GAMEZ/BLES00188″
Step3: Copy the contents of the [TITLE_ID] DIRECTORY to New folder on your desktop
* Contents of [title_id] a)PS3_DISC.sfb B) PS3_UPDATE C)PS3_GAME
Step4: Burn the Contents of the jailbroken game to any type of disc
* Contents of [title_id] a)PS3_DISC.sfb B) PS3_UPDATE C)PS3_GAME
Step5: Insert the Disc in the Jailbroken PS3
Step6: Launch Backup Manager and load the Disk
* Note: The disc icon will not appear
Now it should launch and you can update and play without any problems!
NOTES:
1) You can use Internal Hdd and copy the files using FTP Homebrew.
2) It only can read the jailbroken games that was ripped from discs using backup manager. It can’t read a game that was not backed up by backup manager.
3) If the backup manager could not read the disc, then try launching the backup manager first, then insert the disc. If this still doesn’t work, insert the disc while you are at the XMB and wait until the PS3 reads it as a data disc, then launch backup manager.
4) It has been confirmed by MRelectro713 that it works with updates and saves with no problems.
