I was really struggling to import a ROM collection for arcade where I couldn't get the original Pac-Man to import. Just about every other variant was importing other than the original. So I went back to import the collection again, but this time unchecked (probably way too many) boxes to see if it would finally work. Well, it did it import Pac-Man, but now I have a ton of duplicates of everything. I scoured the settings and only see the clean up media wizard which probably wouldn't solve this issue. It's odd to me that I couldn't get it to import the first time with the default import settings, but besides that what should I do now? Thanks.
