Database help

[Lancerguy]

Hi, I am trying to make a database file and I frustratingly cannot get it to work.  I took the Arcade Capcom CPS-3 db3 file and used TablesPlus as an SQLite editor.  I just added my ROMs to this DB3 file then tried to attach it to my emulator in GameEx but it does not list publisher, number of players, year, description, etc.  The "Name" matches the name in my map file.  The "TOSEC" matches my ROM name.  What am I missing?

Please attach copies of your gameex.ini and log.txt files from when you last tried to access what I am assuming are your CPS-3 games.

You may also want to attach a copy of your modified Arcade Capcom CPS-3 db3 file for review and note, as precisely as possible, what you did to modify the file.
