KOS is an unofficial development environment for the SEGA Dreamcast game console.
It was developed from scratch over the internet by a group of free software developers, and has no relation to the old Katana or WinCE development kits for the DC.
For all documentation, please look in the doc directory. Please read at least the main README file before trying to begin!
You will need to set up an environment variable file, build an SH4 and ARM cross-compiler, build KOS and optionally kos-ports.
An installation script, guide as well as programming tutorials may be found in the wiki at http://dcemulation.org/?title=Development
