Can you make these downloads accessible please?

I tried following the instructions in this post to force MakeMKV to create the dump, but it would not work for me.

The main components of a disc dump file are:
1. discatt.dat - Contains the volume ID
2. MKB_RO.inf - Contains the encrypted media key (MK) for your disc and the media key verification data used to validate the media key
3. Unit_Key_RO.inf - Contains the encrypted unit key(s)
4. kv.dat - Contains several encrypted aligned units (6,144 bytes each) from one or more M2TS files. It is important that these are read after bus encryption has been disabled.

Technically all of the title-specific keys can be derived with only the first three files. The kv.dat file is used to validate the resultant unit keys. This also has the effect of validating the volume ID (VID) and the volume unique key (VUK). Any small M2TS file from the disc can be used as a substitute for the kv.dat file as long as bus encryption has been disabled before copying the file.

Rough outline:
1. Use MakeMKV to start creating an encrypted folder backup of a disc
2. Stop the backup once the discatt.dat/discattd.dat file has been created and at least one M2TS file has been copied
3. Make a new folder for your synthetic disc dump
4. Copy the discatt.dat file and the smallest M2TS file out of the (incomplete) encrypted backup folder into your synthetic disc dump folder
5. Copy the entire AACS directory from your disc into your synthetic disc dump folder
6. Zip up the synthetic disc dump folder, upload it to a file host and post a link here
