I believe that existing keys can be used to derive my TRON Ares variant. However, I'm not able to process the disc and have not found instructions on how to do it. My windows box is not playing nice with my optical drives because reasons. My MacOS drive is doing well for many titles, but not that ...

My Apologies if this disc is "in process" but it seems v82 AACS dumps have been submitted and I have a v77.

I downloaded a new keydb.cfg and am getting a dump file. However, mine appears to be asserting a v77 AACS instead of the v82 the posted dump files imply. Should I submit that too?

Disregard this thread. The disc works on MacOS but doesn't on my windows box because reasons. USB cable. Who knows.

Attempting to rip Flow (2024) Criterion UHD produced an AACS dump file. I did not submit it because it seems that it exists in KeyDB from forum threads.

Running Syncronize then Validate on the disc with KeyDB Helper 1.0.2.1 produced:

Validation failed - VUK/UnitKeys are INVALID!!!!!!!
