I used the Create missing arcade/MAME playlist under tools and it worked great.
The problem I'm having is that when I try to add, lets say a Naomi or a Model 2 light gun game, to the Arcade light gun games list (right click> add to list) it says 1 game added to playlist but when I go to the playlist it is not there.
I'm assuming it is because MAME has these marked as not working, Is there a way to make this work? or do I need to edit a file manually?
I would have thought that it just adds to the list like it does if you make one manually, EMU and everything, just how it is in its native list but I must be wrong.
Edit: I've made manual list from multiple platforms before, I know I can always go to the list and hit "cntrl+A" and create a new list and then add to the new list I, I'm just wondering if there is something simple I missed.
