Fully emulated MS-DOS application. Run nostalgie applications and games...
MS-DOS is an old computer operating system popularly used in 80s and 90s in PCs.
MS-DOS is a text-based operating system, meaning that a user works with a keyboard to input data and receives output in plain text. Later on, MS-DOS often had programs using a mouse and graphics to make work more simple and quick. (Some people still believe that working without graphics is really more efficient.)
In this application, MS-DOS is fully emulated. You can use it to run older games, programs, and also develope dos applications.
