Hello all,
I found the dbx python script elsewhere.
I found an "editor" and downloaded it (no virus found for me, but you can check yourself).
The editor itself did not work, but it came with 2 python scripts, one called archive and one called dbx. I tried them and they seem similar to the ones shown in the screenshot in this tutorial, so I could extract the fbrb using this script and I could extract the dbx.
I also could re-pack the dbx and fbrb folder, I could not verify the work since I am missing some clients to verify changes to the ranking system, but seems working so far.
Thanks again Alecz24 for this tutorial, now here is the link where i found the 2 python scripts:
Best regards
Bone
