Quick datamining/modding notes before I forget. Maybe will save some time to someone.
NTE uses the same launcher as TOF CN, so you can replace the config and TOF launcher will download and update NTE CBT files without phone verification.
AES key is 0x1E17B8C688076277C200F2D6EC065E97035CC96E63EF1D5F9CF78513CA33F222
uasset files are even more fucked up than before, so you need to wait until the pull-request is approved for CUE4parse and get latest FModel later. (Or build them from source if you need that now)
In FModel go to settings and add "Local Mapping File". This one will fix at least image preview
https://files.catbox.moe/rpm8xr.usmap but to view all custom classes we will need to properly dump game type mapping.
Modding potential: fixing file header in uasset is a pain in the ass, but ubulk and uexp files are not encrypted, so you can bake edited textures in UE5.4.4 and use them with original uasset. Can start with that at least.
There is a modded client floating somewhere which allows loading maps in offline mode - haven't got my hands on it yet.
