RISC OS emulation software

DOSBox is a free and open-source MS-DOS emulator. It supports running programs primarily video games that are otherwise inaccessible since hardware for running a compatible disk operating system (DOS) is obsolete and generally unavailable today. It was first released in 2002, when DOS technology was becoming obsolete. Its adoption for running DOS games is relatively widespread, partly because of its use in commercial re-releases of games.

The software program VICE, standing for VersatIle Commodore Emulator, is a free and cross platform emulator for Commodore's 8-bit computers. It runs on Linux, Amiga, Unix, MS-DOS, Win32, macOS, OS/2, RISC OS, QNX, GP2X, Pandora, Dingoo A320, Syllable, and BeOS host machines. VICE is free software, released under the GNU General Public License since 2004.
