September 26, 2010 // 6:37 pm - Today PSGroove has shared details courtesy of inf1 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 PlayStation Archive Utility (or the PARC GUI v0.1 or the PARC GUI v0.2 update by TeamKidneyBean if you prefer).
2) Extract 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 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.

Are you saying you have to use NZhawks program to make this work? Everyone else: Anyone test this?

I posted this question before finding this thread and everyone says it's been tried and does not work.

ChugIt - its NOT possible to do what you say, I took my internal HDD out of my ps3, put another in & placed the original in a usb caddy. When connected via usb the ps3 doesnt pick it up, unless I take the HDD and make it FAT32 on my laptop.

Really? I did the same thing you did, and it's telling me that EBOOT.BIN is not valid. Could you upload your EBOOT?

Drag the big pak22.psarc file into the folder where zlib is, then drag the pak22.psarc file onto the psarc program icon. then copy the newly created pak22 folder to where the pak22.psarc file originally was ex. ?:\GAMEZ\BCUS98123\PS3_GAME\USRDIR\build\main

tried the psarc method with motorstorm 2, the ms2.psarc file was over 4gb so i tryed to split it up the PSARC file.

i even tried to rename it pac22.psarc but every time i droped the file onto PSARC, PSARC crashed. it worked fine when using it with uncharted2 which works fine.

sorry i made a typo with the rename, i renamed it to pak22.psarc still no luck even with the gui versions. all i get is a "working directory" folder created with in the PSARC folder.
