Question though guys.......i seen may cabs with 7 main buttons instead of the 6.....why is this and do you need the 7th button??
i read up and cant find a definitive answer lol
As lamprey says, it's a compromise to suit many game systems. If I was building this, I would keep the encoder PCB out of the control panel and instead tailor the panels to the games/systems I mainly play:
1 x 1 player panel with six buttons and 1 start button (joystick and buttons closer to the center as it's more economical) - use button colours to show button layouts*
(If you wanna play 4-way games, get a stick that's easy to switch so you can pull the panel up and switch it)
1 x 2 player panel with six buttons and 2 start buttons - if you play CPS1 and CPS2 fighters a lot
1 x 2 player panel with 4 buttons and 2 start buttons - if you play NEO-GEO games a lot
* Use NEO-GEO button colours for buttons 1-4 (or get black buttons also and have coloured rims only):
(2) (3) (4)
(1) (5) (6)
or
(1) (2) (3)
(4) (5) (6)
Only make two 2-player panels if you mostly play with a friend/spouse.
