At someone’s request, I created a tool that will decrypt all data in HOARD’s encrypteddata directory.
Running DecryptData.exe will automatically detect the game path and decrypt all files in encrypteddata and write them to their paths under data. I’m not sure if the game will prefer files in the data directory over encrypteddata, but if you rename or delete the encrypteddata directory it will force the game to load everything from data.
I was bored so i played with it a bit myself. The static encryption strings can easily be merged into one.
Since I’m no good with C# I made a python version of it http://pastebin.com/L3TcyWkJ
