"Modder Successfully Runs Unix-Like OS on 30-Year-Old NES Console"
Originally Published 1 year ago — by TechSpot

A modder has successfully ported a Unix-like operating system resembling Linux to run on an unmodified NES, utilizing the enhanced Japan-only equivalent Famicom Disk System's extra memory and storage. The modder, decrazyo, based the OS on Little Unix (LUnix) and overcame challenges such as defining the memory map, writing new system initialization code, and creating new drivers for the keyboard and picture processing unit. Despite visual glitches and slow performance, the project demonstrates that the NES can run a Unix-style OS and was tested on a real American NES through an Everdrive ROM cartridge.
