Maker turns original NES console into Linux desktop PC via FPGA cartridge

Hardware modder Throaty Mumbo has converted an original Nintendo Entertainment System into a functional desktop PC. The project exploits the NES cartridge slot's direct CPU connection, using an Everdrive N8 Pro FPGA-based flash cart to host a custom Linux distro running on an x86 processor. The NES's own CPU handles only keyboard, mouse, and video output duties. A custom adapter translates USB keyboard and mouse input into the NES controller protocol, and a Wi-Fi adapter provides network connectivity. Graphics remain constrained by the NES's native capabilities, resulting in low resolution and limited color depth, but the system is reportedly usable for web browsing.

How the NES becomes a PC

• Cartridge as system bus: Unlike optical media, NES cartridges connect directly to the CPU; the Everdrive N8 Pro FPGA reproduces full cartridge hardware and bridges to an x86 processor
• Linux on FPGA: The custom distro runs on x86 silicon inside the flash cart, not on the NES's 6502-derived CPU
• I/O translation layer: A custom adapter encodes USB keyboard characters and mouse movement into the single-byte controller protocol the NES expects
• Video passthrough: The FPGA sends display output through the cartridge connector to the NES's native graphics hardware, limiting resolution and color depth
• Peripheral additions: Wi-Fi adapter adds network connectivity despite the NES having no native networking support
