Yeah of course.
I attach the exe compiled with static linking of the CRT. This eliminates the necessity of the CRT dlls.

Already done.
There's a whole thread about it at GPG forums: http://forums.gaspowered.com/viewtopic.php?t=1954

w00t!
Decrypt the planet!

I think the chance that somebody can help you is greater if you upload some example files.

I tested on a file. I think this function just decompresses the gr2 file and returns the raw data.

No I think the engine is still called Cry-Engine (2), the game's name is Crysis.

It's the sequel of FarCry. Developped by the German company Crytek.

rsa-crc? ^^

Did you write it yourself? If not, where did you find it?

as always

Today I managed to decompile (AND recompile) all PAK files from the game.

So you wrote a tool? Will you release it?

Yeah but the strange thing is that the last byte is always filled with 00 and the other CDs are always decoded. This doesn't make any sense.
Maybe it's just something to confuse decryptors.

Edit 2: Yep, I changed the last stuff to END and put the "{" below it and it seems the game's main data can be modded now, whoot! I used the jeep as a test and changed a few things for it such as the model. Worked flawlessly, thanks! Where did you change that? In the crypted files? Did yo...

The decryption algorithm is pretty simple. **ENC** is the header. The byte values of the string "RFDBEncode" are just substracted from the data bytes, so real byte = encoded byte - string byte There is some strange stuff at the end the file, those 7 CDs. Don't know why they are there, at l...

Obviously he isn't familiar with debugging. Debugging or at least disassembling the exe often is the most promising approach for (rather complex) encryption. If there is a demo that uses the same format and you give me the download link I might have a look at the algorithm. ;) But as you want to lea...

same here. exams til end of February...
