In brief: We have seen some wild projects over the years when it comes to retro gaming on the Raspberry Pi, but one maker has taken it to a whole new level. Using a Raspberry Pi 5, he's built a stunning, wall-mounted arcade system that combines retro gaming vibes with modern DIY tech. The result is a glowing, pixelated masterpiece that's as functional as it is eye-catching. At the heart of this project is the Raspberry Pi 5 4GB model, which drives four 64x64px HUB75 RGB LED matrix panels. These panels are connected via an Adafruit RGB matrix bonnet, creating a 128x128 pixel display perfect for retro gaming.The entire setup is housed in an IKEA Sannahed picture frame featuring custom 3D-printed brackets, which add a splash of color while holding everything together. It's a clever mix of off-the-shelf and custom components.It's fair to say that the frame alone makes for an excellent art piece. But as you can see in the clip below, the frame serves more than just an aesthetic purpose.Maker and developer John Park's creation is a fully functional gaming rig that runs on the PICO-8 Fantasy Console, a $15 software platform that's compatible with Raspberry Pi, Mac, and Windows. The cool thing about PICO-8 is that it isn't just for playing games; it's also a development tool for coding, creating music, and designing game assets. The system supports a handful of custom titles, all of which have that nostalgic retro feel.To make the magic happen, the Raspberry Pi 5 runs Piomatter, which drives the LED matrix display. A Python script (virtualdisplay.py) grabs the framebuffer from PICO-8, which is launched against Xvfb (a virtual X framebuffer), and feeds it to the LED panels. The result is a seamless gaming experience.For input, Park uses wired USB controllers, and audio comes from an external USB stereo speaker. // Related StoriesIf you're itching to build your own version, the maker has you covered. He's shared a detailed build guide on the Adafruit website, complete with links to all the components you'll need.
