Okay i have here a decrypted file from the game uncharted from ps3, problem is it seems to use zlib compression, hopefully it won't be too difficult to write up an extraction script

Re: Uncharted Drakes fortune PS3 .PSARC zlib
if you use offzip on it it appears they used zlib chunks the start offset if the offset directly after the word zlib.
then it reads zlib chunks till the end of the file.
i am not sure how to read the starting header of the file before the zlib section.

I researched this more with a friend and an extractor should be on its way soon

Hmmm... and all from Uncharted? I only have access to actor20.psarc, and the chunk posted by OrangeC. So if the file isn't using zlib or the zlib block sizes are greater than 64k, then it won't work.chrrox wrote:a lot of different ones they just crash.
Is that the file OrangeC posted? If so, that's only a chunk of the actual music.psarc file.Researchman wrote:Unpacker Error:

Have you tried it? It should work on any zlib compressed psarc files from UDF. For files that aren't zlib, if someone could post a small chunk of the file, I'll try to update the extractor for that type of compression.OrangeC wrote:so is there a fix for this?

Re: Uncharted Drakes fortune PS3 .PSARC zlib
i tried it on files that were zlibbed at the beginning but the data was uncompressed in the middle to the end. it still crashed
i will up a sample in a bit.
