The Bitbox, an open source game console, has received a number of updates in the past couple of months. Last time we covered this DIY console, [Makapuf] had just managed to get the first revision to run a simple game. The second revision will increase the colors to 32k, add another channel of sound for stereo, switch controllers from PS2 to USB, and add support for Olimex’s UEXT expansion devices.
While the hardware upgrades are impressive, there’s been a lot of work on the Bitbox software as well. A new game demo called Fire was created as a set of tutorials to help people start developing for the console. There’s also a BitBoy, a GameBoy emulator for the Bitbox. BitBoy is a ported version of gnuboy for the ARM Cortex-M4 processor that powers the Bitbox. It successfully emulates a number of commercial GameBoy ROMs.
We’re looking forward to seeing what’s next for the Bitbox. After the break, check out a video of BitBoy running on the Bitbox.

A simple resistive DAC is all you need to drive a VGA display. Combining that with an on-chip DAC for audio, the STM32F405RGT6 looks like a good choice for a DIY game console. [Makapuf's] Bitbox console is a single chip gaming machine based on the STM32 ARM processor.
We’ve seen some DIY consoles in the past. The Uzebox is a popular 8 bit open source game system, and [makapuf] was inspired by its design. His console’s use of a more powerful 32 bit processor will allow for more complex games. It will also provide more colors and higher quality audio.
One of the keys of the Uzebox’s success is the development tools around it. There’s a full emulator which allows for debugging with GDB. [Makapuf] has already built an SDL based emulator, and can debug the target remotely using GDB. This will certainly speed up game development.
After the break, check out a demo of the first game for the Bitbox: JUMP. Also be sure to read through [makapuf]‘s blog for detailed information on the build.
