Sorry. It just triggers me, to see a lot of bad button layouts... and knowing that you wanted the possibility to Flip
the thing for Lefties, just made me want to reveal how a change in the layout, would solve all of these issues.
(As that was how things were almost always done in the actual arcade, since their inception)
As for the Coin button.. no offense, but I had the idea too. Its a common idea to have. Of course, having an idea, and actually
building it, are two difference things.
IMO... For the Pinball Buttons, you should replace them with actual Pinball Leafswitches. They react faster. They are more comfy.
And they are nearly SILENT.. compared to the Loud Clickity Clack, of constantly pushing Microswitch buttons.
Also, Id order at least One pinball leaf button, for use as a main controller button. This would be for Rapid-Fire games, like
Halley's Comet, Galaga, etc. You will have less fatigue.. get much faster rapidfire rates. Quicker physical response times. And
enjoy a near silent experience to boot.
I personally also prefer Concave topped buttons. They help funnel your fingers into the center of the buttons, and feel much
nicer to the touch. They help prevent your fingers from accidentally sliding off.. and make it easier to tell which button you
are pressing and then transitioning to. (as you feel the raised ridge edges, as you slide from one button to the next)
Edit:
Maybe add an inch to the opposite side of the stick.. to be able to install a mini spinner. Logitechs weighted free-wheel
scroll wheels would probably work great... but last time I tried one with mame (ages ago), the axis that they use.. wasnt
working smoothly / correctly, for some reason. Point being, its a small free-moving, weighted spinner, that feels good.. and
takes up very little space.
Then, swap the Joystick with a Mini Top mounted button.. like the old Wico bat joysticks.. and you could play games like
Tron, and Mad Planets.
