That's nice for neo geo games but for the many 1/2-button games like Donkey Kong you want the bottom left button to be your action button is a 7 button layout.
I don't. My fingers instinctively go to the top row.
This has been discussed before and IMO it falls among generational lines.
Us old folks who grew up playing on controllers with only one row of buttons go for the top.
Younger folks go for the bottom row for the main buttons, like was on the controllers they grew up with.
Might be wrong or right, but that's my theory.
All of my guests always go for the top row.
Also, if you start on the bottom, you'll end up having to remap ALL the fighting games except for Neo Geo.
