Question about "Serious Engine" ".gro" archives

[L33THAK0R]

Hi all,

Does anyone know if its possible to get the "Serious Engine" ".gro" archives to work unpacked? I'm currently working on "The Talos Principle", which has a significant number of localised language packs I was hoping to rip, however attempting to do so with 7zip causes the titles ".exe" to spout "file integrity fail" errors and the like. Alternatively I was wondering if anyone knows if its possible to remove and add certain files back to the archive post-install. I'd assume you'd have to grab the hexadecimal positions of the desired files but as data-files within ".gro" archives are already compressed I'm not sure how to go about this.

I'm aware it is theoretically possible to re-save all the data-files using the engine editor but this doesn't seem viable for 30k+ files, as well as a handful that cannot be re-saved. I had a brief discussion on the topic with some experienced modders but they haven't attempted to run the title with archives unpacked as its not required, but I was hoping maybe some of you lads have dealt with this tricky title.
