Main thing is comfort dude... if you stack the buttons beside the controllers different you'll have more room for the spinner. Cuz ya don't want that thing sitting on your wrist for the left side player.
The way I have the Spinner above the trackball is actually all measured out so if you are using the spinner , your wrist won't hit the trackball.....and niether player will be near it when in 2 player mode .
I'm going to try an angled button setup later today , but right now I'm working on the thinktank.
Here's the test setup , please note everything is cut 'big' , the control top is big by at least 3 or 4 inches......you can see the actual proposed cut marks.....The cuts into the cabinet are also big.......
-this is just to check stuff out.
The pencil circle is the proposed location of the spinner.....it's outta the way there.......We'll see tho , gotta double check the 'tron' game........
