How about insert russian.txa in general.vt7a?
You can do this by hand.
With a HEX Editor, open general.vt7a and:
- Search for DE94F30C (languages/russian.txa CRC provided by your .list)
- Next 4 bytes are the FileOffset, change to 00A06201 (End of file)
- Next 4 bytes are FileSize, change to your russian.txa file size
- Next 4 bytes are File Compressed Size (zlib), change to 00000000 (This means that file is not compressed.)
- Open your russian.txa with a HEX Editor e copy all data and paste on end of general.vt7a.
- Save mod general.vt7a and test on game.
If game doesn't have any file verification, should works.
PS: Have you tried use the REIMPORT 2?
