Guide: How to Run PS3 Games with 4+GB Files from External HDD

Sponsored Links
212w ago - Today PSGroove has shared details courtesy of [Register or Login to view links] on how to run PS3 games which contain 4+GB files from an external PlayStation 3 FAT32 HDD.

Those interested can check out the guide below, and be sure to share your results in our PS3 JailBreak Game Compatibility List.

To quote: Due to FAT32 limitations users needed to run these games from internal hard drive only. However, it seems that isn't the only option anymore. Many games utilize a file format known as PSARC (*.psarc).

These files ending in .psarc are archive files similar to zip or rar files on PC. By extracting these large archive files and using the smaller files that are inside, users can get stay under the 4GB limit.

This method has been tested on Uncharted II, and will only work on games utilizing the psarc file format.

1) Download PSARC.zip PlayStation Archive Utility (or the PARC GUI v0.1 or the PARC GUI v0.2 update by TeamKidneyBean if you prefer).
2) Extract zlib.net.dll and PSARC.exe to any folder.
3) Find any files more than 4Gb for example /PS3_GAME/USRDIR/build/main/pak22.psarc (5,596,444,529 bytes)
4) Copy pak22.psarc into zlib.net.dll and PSARC.exe directory.
5) Extract pak22.psarc (just drag-n-drop pak22.psarc to PSARC.exe)
6) Now copy pak22 folder with extracted files to gamefolder /PS3_GAME/USRDIR/build/main
7) Now you can delete pak22.psarc.
8) Copy PS3_GAME folder with game to your external fat32 usb hdd GAMEZ/Uncharted2/
9) Use Backup Manager to load game, should work fine.

Still, this is a good idea for games that will work.

it worked for me did you place all the files that were in it instead of the complete file in were you deleted the main psarc file as i tryd it that way and got the same result so i just dragged all the internal ones into there.

don't work, to much fluffing around after so many hours bad result. i tried doing uncharted 2, the program crashed with some problem, than i did it again extracted put the file where had to be and deleted the one over 4gb. game loaded it start i climb the frigging train as the train about to fall there no mountain to jump on to, so my man drake keeps dieing and theres nothing he can do he just keeps dying because there's no platform to jump to lol!

The question is still though how exactly the code used to playback the video later on withing the game itself works and if it's not dependant on the absolute addressing of the file.

I'd be curious to see if it's possible to swap the videos from the 360 version of FFXIII to the PS3 version. Of course that would require the PS3 to have the right codecs and use the same file formats.

A bit off topic: Has anyone tried the opposite? Aka compressing files back to archive. If the games are clever enough to find uncompressed files instead of compressed .. then the opposite might also work.

- games takes less space.
- a LOT faster to copy backups (both for ftp and manual copy the advantage of copying 1 large file instead of a 1000 smaller ones is a huge timesaver .. and with some of these large games we are talking about hours worth of tranfer).

- obviously the initial compress takes time.
- game play/loading slowdown.

Just a silly idea

Another possibility might be if the PSARC format supported file splitting, or if it auto-searched all archives for the files it needed, then creating your own

if i format my external HD to FAT only would 4gb+ work?

if not then if i partition my HD 32gb each then format to FAT32 would it loads 4gb + games?
