Uzebox is an open-source retro gaming console

Uzebox is an AVR-based console that brings back the days of 8-bit video games.

Do you remember reading comic books while waiting for your Amiga 500 to load the latest game, or the joy you felt when slipping in your first 8-bit Nintendo cartridge? We still do, and nostalgically recall a simpler time when many of the games and hardware were easy to use, easy to understand, and most importantly, easy to mod.


As previously reported on Bits & Pieces a few years ago, Uzebox is an open-source console that brings back the minimalist days of video games. Based solely an ATmega644 and an AD725 RGB-to-NTSC/PAL encoder, it uses a split software approach where sound mixing and video signal generation are done in real-time by background tasks, enabling games to be developed in C. They have over-clocked the CPU “slightly” from 20 to 28MHz, but at room temperature, so it’s really not a big deal. Beyond that, the system supports 256 simultaneous colors and four sound channels, and has a SD card interface from which games can be loaded from.


It was the brainchild of Alec Bourque, who created it with one goal in mind: “To be as simple as possible yet have good enough sound and graphics while leaving enough resources to implement interesting games.”

During last year’s Maker Faire, we had a chance to get our hands on the console as we hit the virtual 8-bit ice for a Blades of Steel battle — it was as if we traveled right back to the ‘90s. What’s nice is that Uzebox even uses standard NES/SNES controllers.


Unless of course, you’d prefer a keyboard. That’s because Bourque has unveiled his latest project that has been in the works  for quite some time: the Uzebox keyboard. The interface, which is based on the uber-mini ATtiny25, enables users to connect any PS/2 keyboard to the player 2 SNES port. With the use of SNES controller cord, the interface is so small that it can be easily embedded into an SNES plug or the keyboard itself.
