the L R are left right mouse buttons, iam not really sure if i want those there, or want them on my control panel at all.. iam trying to think how necessary they are
I feel they are, since I play games like Hamsterball on the arcade. Every now and then you may want to play a Windows game that is "arcade like". Plus, if you need to do maintenance your trackball becomes the mouse and the left and right mouse buttons are right there.
That's the thing - you should be able to remap buttons. And if you can't remap buttons, then that game is really no good on an arcade machine to begin with. Because whenever you absolutely
need a mouse, more than likely, you need a keyboard too. And by then, you might as well just bust one out along with a mouse and do your administration.
Plus there's a easy-to-use little program called joy2key than can turn any button into a mouse button if you do need it.
I'm not trying to stop anyone who really wants them from putting mouse buttons on. I'm just out to debunk this belief that they're needed or will save time. Yeah, buttons are cheap. But you're drilling extra holes, running more wire, etc. It just seems like work and a couple of extra dollars (plus space) for no real benefit.
Now on a different note: Clickhea, I actually have my spinner diagonally above my player one buttons, but I still use my right hand and the upper left button. (See pic) After much discussion, this was the best place for my situation since the joystick wouldn't interfere with my reach or play of the spinner. The P2 joystick might be in the way on your drawing. You may want to test that.
