The tool is updated, link is the same.
Now you can decrypt the resources (LUA, FPK, JSON, etc.) while unpacking the archive. Run the tool like this Also the tool now uses dictionary to match hashes.

The hash algorithm is now discovered - it's CityHash64 with seed . in pack01 00004EB7.dat 0000B286.dat 00008994.dat I don't have those but I know what you mean. No, those are not encrypted. in pack02 data\as\tpp\pack\soldier\motion\TppSoldierGzMotion.fpk this is still encrypted? Yes, FPK files are e...

What .dat files?

chrrox wrote:I don't see any model files do you know where they are?

In data\as\tpp\pack I guess.

JSON is encrypted in a same way as LUA.

LUA encryption now also had been discovered. Tool coming up later.

Ok here's the tool.

I have discovered the encryption/decryption method! The tool is coming up shortly. What a hash algorithm they used for previous game versions? I see CRC64 in this game with ecma tab. I don't know the name of the algorythm (and it probably doesn't have one) but here's the code I have reversed from M...

Hash is 64 bit. First two bytes is an extention ID, rest is calculated from name string (without extention if id != 0). Same was in previous MGS games except it was 32 bit and only 1 byte for an extention ID. The original names of data_01.g0s and data_02.g0s are texture.qar and data.qar respectively...
