Dragon marked for Death v2.3.0 (Nintendo Switch) .tb2

[BASgamer]

I got the game files out of the switch a copy of them can be found here

https://github.com/LancerStaff/DMFD-2.3.0/tree/master/Dragon%20Marked%20For%20Death%20v917504%20(010089700150E800)%20(UPD)

The Json are in plain text so could look into those, but havent found a way to decrypt the .tb2 files. Closest i got to that was with peazip and it would at least recognize the extenstion but said archive is not readable would i like to try a password. So, im guessing might be a custom tb2 format or i cant find the right software for it.

Mainly looking into the files to see a list of items/equipment and in the quests which chests can drop the different pieces of gear. My guess would be in sys_item.tb2 or the q_####.tb2 files. Any help in decrypt them would be greatly appreciated.

Any help or advice on things i should try?

Edit: added 2 of the .tb2 files in a zip here for ease of access

It's encrypted there is nothing much we can do without reverse engineering the game.
