The Basement
DOS Arcade
Old-school DOS chess programs, running in your browser through a JavaScript DOS emulator.
The first tab runs games published on this site with a self-hosted copy of js-dos (GPL-2.0). The second streams a catalogue from the Internet Archive, which hosts and emulates those titles itself with its own JavaScript DOS player; this site does not store or redistribute them. Shareware is meant to be passed around; the commercial classics are abandonware, which is not the same as public domain, so the Archive may remove them at any time.
