@Jason Carr Just a heads up, I just audited my spectrum games and it came up with a load of duplicates that are not actually duplicate games. This is because of the side 1 side 2, or tape 1 tape 2 etc., so I'm assuming it will be the same for other tape or disc based systems. Not sure if you can do anything about it, but thought I would mention it. Great work though I have cleared out a lot of dupes!!
