I plan on adding more, I figure there are roughly 500 GB games left, and then I have all the GBC games to add.
I know ioi includes the GB and GBC together, but it would be great of the game database if we could differentiate those games easier. For example, what if a game is named the same. It would be stupid to rename the game to "Tetris for GBC" if the real name was just "Tetris"
