DiRT Showdown (Xbox 360) - .nfs

Post by AnonBaiter »

Here are the samples.

Well, they might work with the codematers_nefs.bms script(at least with x360_001.nfs anyway), but there's something in it that makes them almost incompartible with the script(wrong offsets, etc.).

I tried the usual decryption script toyboxturbos.bms (working on my Codemasters games) but the output is still a mess, which means that this game uses a different encryption or key.

So what`s left to upload? I could upload the default.xex(both encrypted and decrypted) file if you want.

Try with the decrypted one but I promise nothing.

Okay, I`m on it.

EDIT: Here's the decrypted .xex file.

Wait a minute... I think I found out something in the decrypted .xex file...

Code: Select all

Seems that the game does use an entirely different encryption key.
Of course and there's also a "SFeN" index file on the offset 0x4ae0 of the decrypted .xex file.

1-month bump.

So how's it going?

Honestly I don't think someone is working on this stuff. I hope to be wrong :)

At this point, you're not wrong.
Do you still have that decrypted .xex file I uploaded? The key I posted might be a hint.

False sign! According to XexTool, turns out that these archives came from the Xbox 360 version of DiRT Showdown, not Colin McRae DiRT as I expected. In other words, I got the wrong copy and didn`t realize it until now.

Thread has now been renamed to reflect this discovery, thus deleted from my HDD to save space for that game.
