RePlay Custom Drivers & DIY

RePlay provides out of the box support for the following custom drivers and devices:

  • TAITO Paddle & Trackball
  • NAMCO GunCon 2 Lightgun (for CRT TVs)
  • GPIO Joystick (for arcade JAMMA boards)
  • Retroflag 64Pi CASE
  • Retroflag Dreamcase
  • DIY Tilt Addon for RPi5

DIY Tilt Add-on for RPi 5

IMPORTANT: Works only with Raspberry Pi 5.

To build the Tilt add-on, you need:

  • 1× 2K resistor
  • 1× tilt switch
  • 3 wires for 3.3V, GND, and GPIO17
  • A protoboard or PCB for assembly

Circuit description

The connection is:

GND → Resistor → GPIO17 → Tilt Switch → 3.3V

Raspberry Pi 5 physical pins

  • Pin 1: 3.3V Power
  • Pin 9: Ground
  • Pin 11: GPIO17

How it works

  • The 2K resistor acts as a pull-down, keeping GPIO17 at a stable LOW state when the tilt switch is open.
  • When the tilt switch closes (due to movement), it connects GPIO17 directly to 3.3V.
  • GPIO17 then reads as HIGH, providing a clear digital signal transition (LOW → HIGH) that software can detect.
  • This avoids floating inputs and false triggers, ensuring stable readings.
  • RePlay OS includes a new option to enable this feature: ADDONS > TILT INPUT PI5.
  • When enabled, the system automatically rotates the UI and filters the game list to vertical titles.
