The most portable way to play LÖVE, PICO-8, Scratch or your favorite emulated games. Powered by RetroArch!


Table of Contents


We develop a very small, affordable and portable gaming console with a 320x240 display at 120 FPS run by a Raspberry Pi Zero. Gamegirl runs on the Lakka distribution powered by RetroArch because of its speed, fast power-on, instant power-off and its potential to run many retro and hipster-retro games (LÖVE, PICO-8, Scratch and emulators).

Gamegirl Prototype v0.2

Project Goals:

  • Hardware accelerated display
  • Custom software (Lakka / RetroArch)
  • High quality case and buttons
  • Small form factor


  • 1 x Gamegirl custom PCB (audio, power, etc.)
  • 1 × Raspberry Pi Zero
  • 1 × 2.4" TFT display 320x240 (RGB 565 @ 120 FPS)
  • 10 × soft rubber dome buttons
  • 2 x metal dome buttons
  • 1 × 15-16mm speaker
  • 1 × 800+ mAh battery

Build your own!

Prototype v0.2 (released)

v0.2 is the current development platform with multiple working prototypes in the field. It works but it's not perfect, yet!

Prototype v0.2 Front

Prototype v0.2 Back

Gamegirl v0.2 - Schematic

Gamegirl v0.2 - Bill Of Materials (BOM)

Minimal assembly variant

In this assembly variant you will get a working prototype without battery/charging and audio functionality. You can use it only while the Raspberry Pi Zero is connected to a USB power supply!

Full assembly variant

This assembly variant requires some circuit modifications to get audio output!

Gamegirl Case v0.2

A 3D printable case design is currently in work.

Prototype v0.2.1 (Awaiting Prototype board)

v0.2.1 incorporates multiple improvements and fixes over v0.2. If you do not have a v0.2, you should wait for this!

Prototype v0.2.1 Front

Improvements over v0.2:

  • Friendlier hand solderable layout (All component footprints have been expanded for soldering without a heatgun)
  • Fixed mono audio circuit (better pre and post filtering)
  • Fixed backlight function
  • Button placement and labeling to reflect standard Nintendo layout
  • MCP23S17 GPIO Expander replaced Charlieplexed buttons
  • Labeled most
  • Ability to add common inexpensive WiFi adpater directly to the board (depreciated due to Zero W)
  • Replaced battery charger and 5v booster ICs with a 3-in-1 IC, ETA9740 ** Rpi Zero will run directly from battery (Rpi stability has been tested down to 3.0V) ** Increased charging current from 500mA to 2A or 3A ** 5V Boost will operate in USB-OTG mode for accessories
  • Added dedicated charging micro USB port (Rpi ports will be covered)
  • Added multiple power decoupling capacitors for better power filtering
  • Added Safe Soft-Shutdown circuit
  • Replaced latching switch with momentary switch
  • (Optional) Low Battery shutdown
  • (Optional) Low Noise LDO for audio amp (Must cut 3.3v trace when using)

First boot

As of nightly build 20170110005640-r25097, the system will take longer to boot as it is expanding the SD card partition and running other first boot operations. Subsequent boots will be faster.
