You need of all game files because every file has a different encryption key.

Good News this tool decrypt main game files ( 58 GB ) and can be expanded well by xtool
Bad news the game doesn't work properly with decrypted files esp. update files ,
In brief the tool works well with files bigfile.00x.tiger , not update or ultra or languages

I'm really not going to do anything.

I don't have a good sample, someone sent over "bigfile.update1.000.002.tiger" and I had no idea what I was supposed to do with it.

So a sample is still needed

Furthermore the decryption tool doesn't seem to come with source code so coming up with a decryption tool that works with Freearc may be problematic.

I tried to reverse engineer the program and even though I am not good at this, it doesn't seem to difficult to decrypt the game though.

Bro, what method can be used for expand main game files with xtool ?

- The decrypted files cannot be read by the game since it performs the decryption of the already decrypted file, thus scrambling it again.

- The encryption algorithm used here must be a fast one, since the FitGirl repack is MD5 perfect and installs in some minutes - where the files get encrypted again.

In the Fitgirl Setup installer resources of the game, there is a file that caught my attention called tiger.exe. I imagine it must be the file that encrypt *.tiger files again, but idk how to use it.

FitGirl uses this with FreeArc, if you look in setup arc.ini you'll see

[External compressor:tiger]
header = 0
unpackcmd = tiger.exe c - - <stdin> <stdout>

..so yes, FitGirl created this tool (or, more likely, was given by someone..) and it does encodes .tiger files back but not CRC perfect so he uses xdelta (or similar) to correct small differences in files after they are encoded back.

Since FitGirl never shares given tools (or ones created by himself), you ca'nt use this tool since to use it you should have "decoder" part that goes into arc.ini like (for example)

packcmd = tiger.exe d - - <stdin> <stdout>
but since FitGirl never shares tools (I'm not judging, just saying..) decoder part is, of course, missing from this exe

To sum it up, FitGirl has tiger.exe that can be used to decrypt/encrypt .tiger with arc.exe but you can forget about getting it.

Mr. Razor12911 Please, you can do an encrytion tool with reverse engineering starting with TigerDecrypt tool from forum Xentax or Tiger Tool from FitGirl Setup Files ?

Sorry for the disturb ...

I tried to encrypt files again but i wasnt lucky

Meanwhile i upload a sample file, alternatively if you can download a (*.tiger) file from Steam Rip Torrent.

[Razor12911]

I'll check it out, but do remove the torrent before a mod sees it else you'll be in so much trouble

Thanks and ok sir, torrent deleted.

[Razor12911]
