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 one. I just downloaded a new keydb and things are sitll failing.
foo@Foo-MacBook-Air MakeMKV % ls
_private_data.tar keydb.cfg.bak screen.conf
keydb_eng.zip MKB20_v77_POSSESSION_UHD_42CB.tgz settings.conf
keydb.cfg MKB20_v77_TRON-_ARES_8CF9.tgz update.conf
foo@Foo-MacBook-Air MakeMKV % unzip keydb_eng.zip
Archive: keydb_eng.zip
replace keydb.cfg? [y]es, [n]o, [A]ll, [N]one, [r]ename: N
foo@Foo-MacBook-Air MakeMKV % mv keydb.cfg keydb.cfg.bk2
foo@Foo-MacBook-Air MakeMKV % unzip keydb_eng.zip
Archive: keydb_eng.zip
inflating: keydb.cfg
foo@Foo-MacBook-Air MakeMKV % cp keydb.cfg KEYDB.cfg
cp: KEYDB.cfg and keydb.cfg are identical (not copied).

Thanks to everyone who followed the template and provided new disc dump files. The following discs have been added to the public keydb (new media keys are indicated with an asterisk):
Code: Select all
*MKB20_v60_GODS_OF_EGYPT_9D8A
*MKB20_v77_Halloween_2_2605
*MKB20_v77_Halloween_3_9639
*MKB20_v77_Se7en_8EE7
*MKB20_v77_The_Rocky_Horror_Picture_Show_6ACC
*MKB20_v82_Double_Impact_F1E0
*MKB20_v82_Nobody_2_ABD2
As the public keydb continues to grow, there are an increasing number of UHD media keys which can be used to derive complete keydb records for similar disc variants. I strongly recommend Windows users take the time to try
SamuriHL's KeyDBTool as it would've derived & submitted the variant-specific keys and avoided the need to post the following titles:
