One-of-each option?

[kruuth]

Is there some way to add a one-of-each option for consoles? When going through NES and other consoles, you often find 2,4, sometimes 8 different versions of the same rom. For devices like the everdrive this can be maddening. This way there's only one of each game.

Hi.

Can't remember exactly where it is, but there is an option to select "main sets" or "clones", etc. I think it exists during the creation of the datafile. With that, you can filter your datafile to work only with the sets you wish.

You can set filters before importing dat.
Selecting only main games can do the trick. You can also use the 1G1R (1 game 1 rom) option with your favorite language (if the info is available in the dat).
