"well, if you want an "ultimate cp" you need spinners, and topfire joys, maybe weels,yokes, etc, the "ultimate" is near unerachable. but if yours is ok with you, no problem."
To be honest, I have no idea what a spinner is for. I see it on tons of people's examples but have no clue what games use it, so I'm not too interested. And the other stuff is just extra-peripheral to me, stuff I'd only find at a real arcade. When I make a machine I basically just go for the joystick-button kinda games.
"anyway, the day i built my first cp, probably would be one similar to yours.
also, the best metod to see if a cp is well designed, is to make one in a cheap material, like thick carboard or somewath."
