Hardware Overview

The RetroCade Synth is a combination of the Papilio Pro FPGA board, the RetroCade MegaWing, and an optional control dashboard that runs on a computer. The full feature set of the RetroCade Synth requires the expanded memory available in the Papilio Pro FPGA board, we recommend that new users purchase the Papilio Pro and RetroCade MegaWing combo. For users that already have a Papilio One and just want to purchase the RetroCade MegaWing take a look at the Feature Matrix to determine what is supported.

RetroCade MegaWing

The RetroCade MegaWing provides all of the audio hardware needed to make sweet retro music in one convenient and easy to connect circuit board. It snaps into the Papilio Pro and gives it the necessary hardware resources to communicate with the outside world.




  • 2 Stereo Audio Jacks with 18 bit Delta Sigma DAC
  • MIDI In, Out, Through
  • uSD Card for MOD, MIDI, YM, SID, and config files
  • MicroJoystick 4 directions, Select
  • 2x16 LCD Display
  • 16 Analog inputs for sliders and knobs
  • 16 Digital inputs for switches and peripherals

Papilio Pro LX9

The Open Source Papilio Pro LX9 FPGA board is a powerful and flexible platform that provides the core for exciting projects such as the RetroCade Synth and the Papilio Arcade. It acts as the empty canvas that classic audio chips and arcade motherboards can be recreated on. Its flexible nature means that it can be re-used with future Papilio projects by simply purchasing the MegaWing portion of a project.
