[REQ] TDU2 XBOX 360 DDS to STI Converter

[Sylux102]

Game : TDU2
Version : Xbox 360
What it does : Allows ANY dds image to be placed as a sticker file for a car in the game
Reason : To allow better stickers creation (like using texmod for the pc version)
Details :

As I know you are mostly PC hacking group, and this is extremely easy on the pc with texmod, but i am interested in a dds to sti converter for xbox 360 created STI files. There is a link at the bottom to some possibly relevant information on the STI format on the xbox I came up with. Afaik the xbox version has UNENCRYPTED FILES. So this shouldnt be too difficult, but being a noob to reverse engineering idk how to go about this. So im requesting one. I know vettefan88 did this with png to dds. Which that would work too. Any help would be much appreciated. Thank you.

I don't do mods at all, i think you should ask on http://zenhax.com/
It's Luigi's new game research forum to replace xentax, i think he has answer for you. he should have xbox and should know about it, but i'm not sure.

I see. Well i figured id ask since you seem to know how to reverse engineer proprietary file formats. Thank you for your help Sethioz.

[Sethioz]

nope, this is not what i do. i do reverse engineering, but i do not write decryptors or such, that's whole different area.

I may be able to write a converter myself, but i dont know the format. If i knew the format, i could write a little program for it myself. The format is close to another format, but its got wierd byte and word swapping going on.

Mighht you be able to help me understand the format?

[Sethioz]

umm i doubt i know much of it, but you can attach the file.
i still recommend asking on Luigi's Zenhax forum, he knows a lot more about file formats and converters, i think it's job for his QuickBMS tool, but he or someone would have to write a script to be used with QuickBMS.

Well the thread i linked to has most of the important info. Also there is a link to some homemade .sti files. I think its and encrypted .2db, possibly with XTEA encryption. That does seem to be a popular algorithm with this game. But id like to just get verification. Any help is appreciated. Thanks Sethioz.

Sry i can't really bother reading thru it, i was just hoping to see a single file, that's it. but once again, ask on Luigi's forum, he is dealing with such things.
