Atari800 is an Atari 8-bit computer (400, 800, and XL and XE series) and Atari 5200 game system emulator for DOS, Windows, Amiga, Atari ST, Mac, and Linux/UNIX. It includes support for Atari cartridge ROMs, popular Atari disk images files, running Atari binaries directly from the host system, and accessing the host filesystem from within the emulated Atari.
DOSBox uses SDL to emulate the PC hardware required for running old DOS games. This includes a 386 processor, an S3/Trio video card with some tweaks to allow for older display hardware like the Tandy, a Sound Blaster Pro, the PC speaker, Tandy 3-sound, CMS/GameBlaster, Disney Sound Source, and MIDI. DOS emulation is integrated. It is possible to mount local directories as drives inside the emulator.
