GT5P gamesaves are easily transferable to anyone with the same game type and Spec. There are six current (Spec III) types; Three formats (Japan, PAL and NTSC) and two sources (Blu-Ray Disc and PSN Store download). Backing up your own gamesave to PC: Start on PS3: This is done on the XMB screen without a game running, it does not need to be Signed In to PlayStation Network. Plug USB drive into PS3. Go to Game column. Go up to "Saved Data Utility (PS3)", press X. Find your gamesave on this list, most recent saves are at the top. Press Triangle (for Options) when on your GT5P game save (subtitled "Data containing details of your progress through the game). Top of option list is Copy, press X on that. Select the destination screen is next, select your USB drive from the top of the list. Press X. Once completed you can remove the USB drive. Finish on PC: Plug in USB drive. Find "PS3" folder, right click on it, cursor over "Send To...", select "compressed (zipped) folder" Name it something clever like "GT5P data", and move it somewhere you won't forget about it. Using a zipped (your own or a downloaded) gamesave: Start on PC: Plug in USB drive. If there's a folder on it called "PS3" you've already been playing with this. If it exists (it gets auto-created by the PS3), move it to your PC and rename it something other than "PS3". Download Zip file (from Email or forum) or move your own zipped file to the desktop (desktop is easiest to find). Right click on it, select "Extract Here". Right click the "PS3" folder that just appeared, select "Copy". Open/find USB drive and paste (or press Control-V, same thing). Close USB drive folder(s) and remove it from your PC. Finish on PS3: This is done on the XMB screen without a game running, it does not need to be Signed In to PlayStation Network. Plug in USB drive. Go to the User you want this gamesave to be attached to. Go to Game column. Go up to "Saved Data Utility (PS3)", press X. Top of this list will be the USB drive (it may even be named), highlight it and press X. The Gran Turismo 5 Prologue save should be there, press Triangle (for Options). Top of option list is Copy, press X on that. It will tell you Copy Completed, now you have a good gamesave on this user. Make sure to redo all the options, button mapping, etc how you like or need them now.
