There are two lists that are built in for that. 1) multi-player = 2+, 2) 4 player. If you want lists for 2 player, 3 player, etc, you will have to construct it manually. There are info files that list the data, but it will have to be compiled in a MAME43 format and put in your "custom folders" location. Actually, there was a thread I just helped with yesterday that had a list already constructed. Hopefully Creek won't mind sharing his list. Folders_GameEx.zip
