MAME Cabinet Parts & Controls — The Complete Builder's Guide

A MAME cabinet is only as good as its controls. Emulation gets you the games; the right joystick, spinner or trackball gets you the feel. Every GRS control below outputs standard USB HID — plug-and-play with MAME, RetroArch, RetroPie and Batocera on PC or Raspberry Pi, no drivers needed.

Match the control to the games you play

Wiring it all together

Buttons and sticks are simple switches — they need an encoder to become USB input. The GRS Zero Delay Encoder V2 handles a stick + buttons; the Universal Encoder Hub connects a full panel — sticks, buttons, spinner and trackball — over one USB cable. Grab matching wiring harnesses and you'll never touch a soldering iron.

MAME setup tips

• Set spinner/trackball sensitivity in MAME's Analog Controls menu per game — start at default and adjust to taste.
• Use the TOS restrictor's switch (or servo version) to flip 4-way ↔ 8-way per game — diagonal misreads in Pac-Man are a gate problem, not a stick problem.
• Map controls once in RetroArch/MAME and save per-game overrides — all GRS parts enumerate as standard HID devices.

FAQ

Do GRS parts work with Raspberry Pi / RetroPie?

Yes — everything is standard USB HID. Pi 3, Pi 4, Pi 5, RetroPie, Recalbox and Batocera all recognize the controls without drivers.

What's the difference between a zero-delay encoder and the Encoder Hub?

The Zero Delay V2 is the simple, proven board for one stick and buttons. The Universal Encoder Hub adds ports for spinners, trackballs and more complex panels — one USB cable out.

Can I mix GRS controls with other brands?

Yes. Each control is its own USB device (or wires into the Hub), so you can add them to an existing panel one at a time.
