I found the iCade buttons far too noisy and clicky so I've replaced the microswitches with GroovyGameGear's micro-leaf microswitches. They replace the iCade's microswitches using the original buttons so it is easy to do. The difference is dramatic, they feel like original arcade leaf buttons, i.e. quiet, quick and no click. Now I've done those the joystick could do with the switches replacing but these micro-leaf ones don't fit that. Here's what the button wiring looks like. It's simply a matter of removing the microswitches and replacing them with the micro-leaf switches. To attach the new micro-leaf's attach one end vertically, push down the switches metal arm with something like a screwdriver, otherwise the metal arm may break, and turn the micro-leaf until it clicks into the other mount. Push down the metal connectors and then attach the wires.
