Nintendo DS Operating System - made by fincs - Hosting generously donated by mtheall - IRC channel: #FeOS at irc.blitzed.org
Last update: February 11, 2012
FeOS is a free, open-source operating system for the Nintendo DS. Its aim is to provide a usable abstraction layer that builds on top of said platform. Because the Nintendo DS is a very resource-constrained platform, a port of a multi-platform OS is utterly pointless, even if said OS is designed for embedded platforms. Therefore, the OS must be specifically written for the DS.
FeOS nightly build - updated every minute if there's a change in the official Git repository. It also contains several of mtheall's applications and libraries.
