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

Q: Can I mix GRS controls with other brands?

Yes. Each control is its own USB device, so you can add them to an existing panel one at a time.

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

If you play…	You need	Our part
Pac-Man, Galaga, Street Fighter, Mortal Kombat	Joystick with the right gate — 4-way for the classics, 8-way for fighters	GRS joysticks + TOS switchable 4↔8-way restrictor (switch per game)
Tempest, Arkanoid, Breakout, Pong	Weighted spinner	GRS spinners — see the Tempest setup guide
Centipede, Missile Command, Golden Tee, Marble Madness	Arcade trackball	GRS trackballs — see the Centipede guide and Golden Tee guide
Ikari Warriors, T.N.K III, Heavy Barrel	Rotary joystick	GRS IKARI Rotary — the only SNK-licensed one

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. Starting a panel from zero? The GRS LED arcade DIY kit ($19.99) packs the encoder, ten pre-wired LED buttons and a joystick in one box.

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.
