EUzebox - a retro-minimalist 8-bit open source game console

The EUzebox is a Uzebox-compatible DIY game console kit for the EU region with a SCART interface. It is based on an AVR 8-bit general purpose microcontroller made by Atmel. The particularity of the system is that it uses an interrupt driven kernel and has no frame buffer. Functions such as video signal generation, tile rendering and music mixing is done in realtime by a background task so your game can easily be developed in C. The design goal was to be as simple as possible yet have good enough sound and graphics to implement interesting games. Emphasis was put on making it easy and fun to assemble and program for any hobbyists.


Important: A TV set with a SCART input (RGB) and and support for NTSC video is necessary for this kit!

  • Low parts count and cost: The system is made of only one chip and discrete components.
  • SCART connector for video & audio output
  • Interrupt-driven kernel: No cycle counting required, sound mixing and video generation are all made in the background.
  • 256 simultaneous colors: Accomplished by using a R-2R resistor ladder DAC.
  • 4 channels sound engine: The sound subsystem is composed of 3 wavetable channels and 1 noise or PCM channel.
  • optional MIDI In: With a music sequencer, allows the creation of music directly on the console.
  • Retro controllers: The joypad inputs uses standard NES/SNES controllers interface.
  • SNES Mouse Support.
  • SD/MicroSD card interface.
  • Expandable: I/O lines and peripherals are still available, like the UART and SPI port
  • Gameloader: Load and flash games stored on SD cards.
  • API: Develop games using an API that provides multiple video modes, sound driver and more
  • Open source: The software and hardware design are totally free and licensed under the GPL.
