Duplicate titles

[Reevesad]

I guess the reason why I have duplicate roms on launchbox is because of the two different filenames

the files are named as

._Mario Party 6 (USA).7z

Mario Party 6 (USA).7z

if I can delete a file, which one do I delete? and what is the easiest way to delete it?

so many questions, sorry Newbie!

If they both work  it doesn't really matter which one you get rid of but I would remove the one with the underscore in front. You can simply right click a game and delete from the context menu
