If you can't run Python(.py), you can try the exe from the remove copyright mod.

============
Installation
============
Put 4 files (0xdddddddd.fdata, 0xdddddddd.yumiamod.json, yumia_mod_lib.py and yumia_mod_insert_into_rdb.py) to your game folder\fdata_package
Usually it is
C:\Program Files (x86)\Steam\steamapps\common\Venus Vacation PRISM - DEAD OR ALIVE Xtreme -\fdata_package

Then run yumia_mod_insert_into_rdb.py in that folder.
You may need admin right to run it.
If no backup exists, it will write a backup (root.rdb.original and root.rdx.original).
It will always start from the original backups, so that duplicate mods will not be inserted when run repeatedly.
After running the script, root.rdb and root.rdx will be updated and the mods will have been inserted into the game.

For more information about the Python script, please find in Atelier Yumia fdata mod toolset github:

=======
Warning
=======
Because the script is always start from the original backups.
If a game update overwrites the root.rdb and root.rdx, then you should delete the old orginal backups (root.rdb.original and root.rdx.original).
So I recommend backup your root.rdb and root.rdx manually after every game update.
