[Help] Lego Legacy deobfuscate png files

[AsparagusCute1467]

Tried to get some png files from "Lego Legacy: Heroes Unboxed", and as usual with Gameloft they are obfuscated. The content of the files start with "GCBF", so I guess they are not compressed additionally. I tried the "gcbf_versus.bms" script from http://aluigi.altervista.org/quickbms.htm but it didn't work (No error, just a still broken png).

In the attached zip are two files:

• yeti.png - the expected result should look like this
• minifig_col170_decal.png - the obfuscated file

Has somebody any idea what I'm missing? Or maybe even a working solution?

Forget that I ever asked!

QuickBMS with the mentioned script is working perfect! I just missed the part, that the resulting file is a ktx file and not a straight png. So with an additional step I've got the pictures.

Hey!!!

I am very interested by this problem. I tried to rip files from LSW Castaways, gameloft video game too. I had tx, bdae and broken png files. With GCBF script I managed to get dat files, but bdae became BRES and png became KTX file. How did you manage to get rid of ktx file and get a straight png??

Thx for helping me

Here you will find tx, bdae and png I tried to work on
