But... will it work the other way around, I find that the best game play and most intriguing stories are in the adult games. I want to build a dedicated adult quiz/nude puzzle cabinet with none of that classic arcade or '90's fighter crap on it, only quality adult arcade games.
Seriously though, I used MCM for some ROM management a while back and was very pleased with the results, it also allows you to remove titles based on their controls and/or type of game if I remember correctly. I think I used it to ditch all the mahjong and trivia/quiz games too.
The downside is that now I have about 1.5 times the total disk space taken up since there are times when it is good to have the ROMs exactly as you got them, it can make maintaining your collection much easier and faster.
