Lots of people's setups have the 7th button below and to the left of the other 6. I know it's always stated it's for some NeoGeo games but which ones in particular use that 7th button)
I'm in the beginning stages of laying out my CP and am just trying to figure out if I really need 7 buttons or if 6 will be just fine.
I did use SortInfo to get a list of the games and how many buttons they use but I've never heard of most of the ones that are listed to use over 6 buttons.
