This is what I use step by step to get burnt games to play. You need:
1) Jailbroken PS3 system
2) Backupmanager 1.0 installed (havent tested on 1.1 but assume it works since nothing major has changed)
3) USB External Had Drive
4) Imgburn (source below)
5) Original PS3 game
It is very simple once you have everything above.
1) Jailbreak your Ps3 with normal methods (I use the TI-84 Calculator)
2) Go to backup manager and backup your original PS3 game to your external hard drive (I have yet to test from internal and FTP method)
3) Unhook the External Hard drive form PS3 and hook it up to your windows based PC (i use 64 bit windows 7)
4) Find the game you copied in the "GAMEZ" FOLDER (It will not be labeled with the game name, it will be BLUSxxxx you can find your BLUS game number on the cover of your original game or side of it. Then copy it to an easy to locate place on your Hard Drive, I use my Desktop
5) Once the files have been copied, open IMGBURN
6) Select the "Write Files/Folders to Disc" (Leave all settings as default)
7) Open your BLUS folder, there should be 2 folders and 1 file inside, drag and drop the 2 folders and the 1 file into Imgburn
Insert your media of choice that will hold the size of yoru game
9) Burn at 1x speed (I know its slow but quality of quantity ALWAYS)
After the burn is done:
1) Turn on your jailbroken Ps3 again, insert the game at the XMB menu (will show as a data disc)
2) Go into the backup manager
3) The game should show up (for dvd-r and dvd+r DL it showed up as BLUSxxxx but for bluray it showed the game title and picture like normal for me) Don't backup just press load, and away you go.
Download ImgBurn from:
[You must be registered and logged in to see this link.] ImgBurn will autoconfigure everything for you, download it and install. Leave all settings default. When you insert your disc (DVD-R, DL or BD-R) Imgburn picks the best settings for you when with the size and media type you have. All I have done is what is listed above and pressed burn, works for me.
