Hi all, got what I imagine is a pretty basic question here. I have 1G1R collections based off of Redump and No-Intro sets loaded in Launchbox. They've been checked against current DAT files so I am sure they are correct. I'm interested in finding playlists that have best/top games by platform and/or genre that map to these sets. I've come across some playlists downloads on the forums, but I'm a bit confused how it works. Do I need to make sure that the playlists are set up to work with No-Intro/Redump sets? If not, how does it identify which game is in the playlist (i.e. is it only based off of game title)? How do games present on the playlist but missing in LaunchBox factor in? Thanks for any help.
