As the topic suggests, I'm hoping there exist ways of filtering clones for other platforms besides MAME. In MAME's case, AttractMode can make use of certain text files to get this done. Right now, for example, I'm trying to get my Atari 2600 collection sorted. There are DAT file resources for the 2600 and others, but I don't know whether AttractMode has the means for processing them.
Barring that approach, I'm looking for suggestions. If I begin with, say, Good2600, with its literal dozens of clones and hacks for each game, what can I use to pare it down to only games that provide essentially unique iterations? Googling around led me to an app from 12 years ago called Romsorter, which I did locate, but which fails to run under any circumstance on my modestly modern OS. Other than that, I don't have any good ideas. I can't simply move filenames with certain strings, because that would capture, e.g., games that were exclusive to certain territories.
