[Help] Repacking .lh2 files into .ols for Dante's Inferno (PS3) - Localization

Hi everyone,

I am currently working on a fan translation and localization project for Dante's Inferno on the PS3. (Polish TRANSLATE)

I have successfully extracted and edited the game text, but I am facing a major roadblock with the rebuilding stage. Specifically, I need to pack and compress my modified .lh2 files back into the original .ols container archive format. 

It is absolutely crucial that the original file structure and directory layout are strictly preserved so the PS3 runtime can read the assets without throwing errors. I've tried standard extraction tools, but recompiling them back properly has been tricky and often causes crashes.

Could anyone recommend a specific script, a tool, or the correct command-line arguments to repack these files into .ols while maintaining the native compression structure? 

Any help, templates, or guidance would be highly appreciated. 

Thanks in advance!
