That makes no sense. Have you tried this as importing files? See in the top right, the windows search bar I have put *.cue it is just showing my ps1 .cue files. I then click one and ctrl a to highlight them all and import them as files?
OK make sure you have no amiga cd32 anywhere in launchbox, any spelling doesn't matter delete it, through tools/manage platforms. then start from the beginning with a import.
OK, lets start from the beginning, go to tools manage platforms and delete Amiga cd32 or whatever you have it called, Then re-import don't download media as you already have it, and it should be all good.
Yes, delete through there 1st. That should of removed all the xml files. then you re-import. The reason the import duplicates worked is because the games where still there somewhere so when importing you did not add any new games, so zero found. checking the add duplicates just imported all the same games again.
Sorry ill rephrase that, you haven't deleted them from launchbox, so when you tried to add them it said zero inported because they where already there, so telling it to add duplicates just repopulated it.
Glad it worked for you. they were considered duplicates because you haven't actually removed them from launchbox. It was just a hunch I had. Glad its working for you now though.
