All SNK Neo Geo AES roms are inherently included and mixed in with the MAME roms. However, I like having them separated out for nostalgia sake. Growing up, the Neo Geo was the best, elite, and most unobtainable console so I like browsing them separate from the other arcade games. Additionally, unlike arcade games, the SNK Neo Geo AES games all have boxes, carts, and user manuals which display nicely as a set.
The problem I'm having is when I import the roms from a folder in LaunchBox, choose SNK Neo Geo AES, and point it at my MAME roms folder, it wants to import all the roms.
How can I have it only import the SNK Neo Geo AES roms?
