I'll be doing seven buttons in my build this summer, but I'm not sure where to place the "extra Neo-geo" button. I know most cabs have 3 on top and 4 on the bottom like this:
123
7456
That just seems more of a pain because you'll have to specially map the 7456 for all Neo-geo games (I guess not that big of a deal). I just seems more simple to do this:
1234
456
Here you don't have to reprogram for specific games if you wire both #4 buttons to the same input on your interface. Use the 3 over 3 for Street Fighter type games and the 4 on top for Neo-geo. This just seems so simple, but then I may be missing something....any thoughts from the experts?
