supports:
- browsing the bigfile file system
- unpacking the bigfile into individual files
- repacking individual files into one bigfile (hasn't been tested on the lastest version of the game, only the beta version)
also contains a unity project that you can use to import and view textures from the game. i was planning on adding everything required to browse the maps before i got caught up with other projects, but the basic architecture required is there.
you will need a version of unity (only tested with 2018.3). drop the UnityEngine and UnityEditor dlls into the bin
folder.
