Quick way for decrypting all the files of Race WTCC Needed stuff: http://aluigi.org/papers/wtcced.zip http://aluigi.org/papers/wtcced_all.bat http://gnuwin32.sourceforge.net/downlinks/findutils-bin-zip.php http://gnuwin32.sourceforge.net/downlinks/libintl-bin-zip.php http://gnuwin32.sourceforge.net/downlinks/libiconv-bin-zip.php Then: - create a new folder in C: called wtcced (c:\wtcced\) - copy your GameData folder in C:\wtcced - copy wtcced_all.bat, wtcced.exe, find.exe, libintl3.dll and libiconv2.dll in c:\wtcced - execute wtcced_all.bat - at the end of the process you will see a new folder called decrypt (c:\wtcced\decrypt) containing a new GameData folder with ALL the decrypted files if you want to re-encrypt them just do the same (obviously remember to move the new files in c:\wtcced), the tool will encrypt them automatically. if you need to change encryption type or other things, just modify the .bat file
