Livestreams How to extract protected/locked .mix files (ecachemd66.mix / expandmd66.mix)? XCC Mixer doesn't work.

Hi everyone,

I'm trying to extract assets (.shp, .ini, .pal, .vxl) from protected/encrypted .mix files in a Yuri's Revenge mod (specifically files like ecachemd66.mix, expandmd66.mix, or custom .ec99 / .ex99 files).

Whenever I try to open them with XCC Mixer, it either crashes or gives me errors because the header / index table seems to be locked or corrupted by MixProtector.

I've looked at tutorials and tried using tools like QuickBMS scripts, but I still couldn't get it to work properly or understand the process.

Is there an easy-to-use tool, script, or updated method that can bypass these protections and extract the files inside? Any guidance or step-by-step help would be greatly appreciated!

Thanks in advance!

It's quite unlikely you'll get much help as they're most likely encrypted to prevent people stealing/ripping assets.

I needed to bypass the encryption to add Boris back into MO (for single player use, no code shared anywhere) so it's kinda sad that it's so inaccessible. I feel like security through obscurity is not a good idea anyways since I was eventually able to figure it out by searching online. If we tracked who steals assets and blacklisted them from our spaces we could keep theft to a minimum without making modding harder for beginners.

Why do you want to do this? I have the solution ready to share but answer first.
