The Internet Archive has made almost 2,400 old MS-DOS games accessible. The games can be played for free here, simply using your mighty web browser. The browser-based emulator is a project still in beta, so be prepared for bugs (but isn't everything a bit buggy these days?!). Ready yourself to revisit the original Prince of Persia as well as Wolfenstein 3D, Bruce Lee and Centurion: Defender of Rome. Lovely stuff indeed!
