1. Download this file. You must login or register to view this content.
2. Extract the folder.
3. Put the psarc file into the folder you extracted.
4. Drag the psarc file to psarc.exe
5. Drag the newly created psarc folder into where the psarc file was.
6. Delete the .psarc file because you don't need it anymore
7. Run it, and it should work.
For example

i have uncharted 2 and the psarc file is in /ps3_game/usrdir/build/main/
i would copy that to the folder where the program you downloaded is. (c:\...\downloads\psarc\). You would drag the psarc file to the exe and it would make a folder. I would then copy that folder to /ps3_game/usrdir/build/main/ and delete the original .psarc file.

Hope i helped :d
i might make a thread out of this if no one really knows how.

and is this method for external

Alright for the people that keep getting a black screen. Heres what I did fix the problem

First of all large folders will be needed to be split up, Soo depending on if you ripped the game from a disk or downloaded it, If you ripped it from a disk (Assuming this is multiman) it would have split big folders in to little psarc files,

eg. data_ps3.ps3.psarc.66600
data_ps3.ps3.psarc.66601

these will be found under..GAMEZ\BCES01007-[Killzone3]\PS3_GAME\USRDIR

If you have downloaded the game, You will need to get OpenSplit V1.2 (google it) then Click "Split big files to .666xx" then navigate to your killzone file and let it run.

After this you will have a list of psarc files in the USRDIR, Alright now copy those files to your computer.

Next you will need to open up OpenSplit V1.2 again and then click on "Merge .666xx to big", then select the folder you placed those folders. The program will now merge all those folders into one big psarc file.

From here you need to download PSARC (google it, was the first link on the list for me) then drag that big psarc file into the folder you have placed PSARC.exe, then literally drag the large psarc file ONTO the PSARC.exe

Ok.. now PSARC will start rambling on about all the shit it is extracting so just let it run its course (may take a while), it will turn that file into a few folders that you will then place back into your portable hdd in the same spot u grabbed them so for me it is GAMEZ\BCES01007-[Killzone3]\PS3_GAME\USRDIR
(if you ripped the game from a disc you can now delete the split up psarc files in that folder.)

then run lv2.pkg, run multiman, enjoy

note* If you have trouble with any of this or i didnt quite explain something right just quote me here or send me a msg
