For help running MS-DOS games on modern operating systems, see the DOSBox guide.

MS-DOS is an operating system marketed by Microsoft. As a result of being distributed on IBM systems (under the name PC-DOS) it soon became immensely successful, and the platform of choice for computer games. Even after the release of Windows 95 many games were still produced primarily for MS-DOS, albeit including some additional features when run under Windows. Once DirectX gained widespread support, MS-DOS was quickly abandoned by developers.

On more modern versions of Windows many MS-DOS games will not run correctly, and, just as often, many will not run at all. One popular solution for running these games correctly is the open-source emulator DOSBox.
