Borderlands 2 Compression Toolkit

[Idlehands88]

Updated build, hopefully corrected all incorrect values when recompressing.

Thanks man, but it still doesn't work :'( I tried it on 3 of my saves and it corrupts them everytime, the Compression tool does fix the checksum right?

nice work on this toolkit fairchild

Yeah it looks that way we have figured out the compression now just need a checksum fixer

Have you checked that it's not huffman encoded like the savegames? If you have the lzo decompressed data of the gpd's savedata i can check real quick if it's huffman encoded.If not i guess i can have a look at it when i'm done creating the compression process of this tool :-)Edit:Updated first post with the latest build, this has compression support (may not work as expected).

The GPD uses LZO1X compression. I said this weeks ago. The hash on the data is 160bit (not sha1 or ripemd). I can't upload the data right now because I'm on my iPhone, but the data is in TitleSpecific1 of the gpd.

When I tested it with the PC's profile data, it matched the data with the gpd. I was able to mod it, and I only fixed the SHA1. I'm not sure what 160bit hash your referring to. Unless your talking about the two strings that show up after you start the game.

hey fairchild.

any plans to put a gui around this once its perfected to make it easier? kinda like what kill_seth did.

is there a way you can add ps3 support if i send u a copy of my save?

No, I'm not referring to the String's in the savedata... I've checked several profile's gpds and the 160bit hash at the begin of the savedata is not a basic SHA1... I will include the files that I'm looking at and you can see.

I've included:
- BL2 GPD
- entry # 0x63E83FFF
- entry # 0x63E83FFF's savedata (0x0 = byte[] 160bit_hash, 0x14 = int32 decompress_length, 0x18-EOF = byte[] compress_data)
- compressed data (0x0 = int32 decompress_length, 0x4-EOF = compress_data)
- decompressed data (uses basic UE3 savegame struct)
-I also included a HexWorkshop bookmark for : entry # 0x63E83FFF's savedata

How you get a SHA1 hash from any of the entry's data is beyond me...lol
