 +1G1R stands for "One Game One ROM". It is used for consoles rom and it means that you get only one file imported per game.
 +Consoles dat often list a lot of regional versions of one game.
 +Let's take an example. In the snes datafile, you get:
 +    Super Mario Kart (Europe)
 +    Super Mario Kart (Japan) clone of "Super Mario Kart (Europe)"​
 +    Super Mario Kart (USA) clone of "Super Mario Kart (Europe)"​
 +There is only one game here, with 3 specifics regions versions. If you load that dat as-is in romcenter, you will get one main game (europe), and two clones.
 +Now you probably only want to see one version, the one for your region, and really don't care about the others.
 +The solution is to enable the region filter before importing the datafile and give your regions preferences.
 +For example, set 'USA, Europe and Japan' in this order, and romcenter will only import the game with the best match. Only '​USA'​ version will be imported as '​main'​ super mario game.
 +Note that games not imported won't be known and identified by romcenter. They will appear with grey icon (unknown) and will be removed if you ask for a fix.
 +Not all datafiles are eligible to 1g1r feature, the '​region'​ data must be available with games.
 +Head to for compatible dat and more info.
