I've managed to modify the file so DB Master 15 and 12 can read the file, but I can't make a new version. Seems like the hashes are not correctly recalculated (At least for this game).
I modified NHL games big endian localization .db files swapping index table values to little endian then DB Master can read the file. After DB master editing swapping little endian back to big endian and then open the file with Generic EA DB Editor (https://forums.operationsports.com/forums/ncaa-football-rosters/590543-generic-ea-roster-editor.html
and just save the file and it calculates hashes correctly. Xml file for DB Editor in attachment.
Edit: I toggle tools->calculate all hashes before save the file in DB master then open the file in DB Editor and save the file and it repairs crc32 hash values in the index table and other at the end of the file.
