Is there a way to decrypt the .hat files of Race07 (and the GTR Evo Add-On) with wtcced 0.2.2?
This is the only file that cant be decrypted...the rest works perfect!

Greetz!

the .hat files are simply gzipped (you can verify this because if you open them with a hex editor the first 3 bytes are 1f 8b 08).
So add a .gz extension to the file (like 2007_ANDERSTORP.hat.gz) and open it with your default program like 7-zip or winzip

I just wanted to let you guys know that GTL has finally been cracked (well, back in May already, but I just learned of it now). *waves goodbye to Starforce*

wtcced is a console application so you need to run it from cmd.exe as explained here:

http://aluigi.org/about.htm#howuse

then using it for decrypting a file is just basic:

wtcced.exe yourfile.gmt newfile.gmt

the tool can also work with multiple files and can also overwrite the original one (in case it's needed):

any experience with ARCA Sim Racing 08? gMotor2 as well, but the WTCC/Rfactor gmt decrypters say not in WTCC format.

Would a sample gmt/dds/aiw etc. be helpful?

Attempting to do some billboard updates for thier game, but since the textures are encrypted i cant!

when in my previous post I said that I had no success I don't remember if I referred to the fact the game must be purchased (and so I had no files) or something else.
the only thing that I know now is that the executable uses the same encryption algorithm of rfactor so:
- have you already tried my rfactordec tool with these files?
- can you provide one of these encrypted files?

ok I have checked the ARCA files and the algorithm is just the same, except the signature which is no longer "fixed".
I have released a new version of rfactordec which has no longer the signature check and so can decrypt these files perfectly.

wild!

sadly, the dds appear to be encrypted too

i tried to use rfactordec to decrypt these, and its says it worked, but the files still dont open

any guesses?

Sample DDS file

uhmmm that file is strange because lacks of the 20 bytes header containing the signature/key and the 4 bytes to skip so at the moment I don't know what type of encryption it uses or if it uses something like a "default" decryption key.
I have found the various MAS containing it so I will check it later, but for the moment there are no news.

ok I have solved the mistery, in the DDS are not used the 4 bytes to skip.
the only problem remain the DDS you uploaded because is the only one that can't be decrypted, if you can post the full path of the MAS containing it.
here I have tried with GameData/Tracks/ARCA_Daytona/ARCA_Daytona_maps.mas and works

I will release the updated rfactordec later, but I need to know if there are also other encrypted files other than GMT and DDS because that thing of the 4 bytes not encrypted seems related to the extension.

perfect, and I have found also other extensions.
in short "seems" that only the GMT files have 4 bytes to skip, all the others don't have them.
now I will release the new version on my website, remember to re-download it (otherwise doesn't work with TGA)

just released 0.1.2:

http://aluigi.org/papers.htm#rfactordec

I have also solved the problems of knowing if the input file is encrypted or not because just like the rfactor's files also those in ARCA have a signature:

Luigi,

seems all tracks are using a different key

just tried to decrypt ARCA Iowa's files and it says unknown key!
