Free Atari Emulators

Atari ST, 800, 800XL, 130XE, 5200 (etc) Emulation

Free Atari Emulators

Are you feeling nostalgic, yearning for a taste of the good old days when you played games or learned to write your first program on an Atari computer? The free Atari emulators listed on this page allow you to revisit those days using your modern computer, be it a PC, Mac or some other machine.

The emulators listed here typically emulate the Atari ST, 800, 800xl, 130XE and 5200 machines. They usually provide emulation for a variety of Atari hardware, including joysticks, track ball, paddles, touch tablet, light pen, light gun, cassette recorder, floppy and hard disks. You will probably also need Atari ROMs (which may or may not be provided) for the machines to use the emulator. If you are able to locate standard disk images for old Atari software, like games, these emulators will also be able to load them as though the images were normal disks in the floppy drive or cassette tapes in the recorder.

ARAnyM (Windows, macOS, Linux, FreeBSD, OpenBSD, NetBSD, Solaris) New

ARAnyM, or "Atari Running on Any Machine", is a 68040 emulator. Specifically, it emulates an MC68040 with an optional MMU, an MC68881-compatible floating point unit, up to 4 GB of RAM, host-accelerated graphics, with direct access to many resources available on the host machine like sound, disk drives, CD/DVD drives, parallel port, etc. As such, it can serve as a more advanced/modern Atari machine that can run 32-bit Atari ST/TT/Falcon operating systems, and TOS/GEM applications. This is open source software, released under the GNU General Public License.

PCE/atarist (Windows, Unix-like)

PCE/atarist is an MC68000 emulator for various Atari ST and Mega ST models. At the time this entry was written, the ready-to-run downloads available emulate an Atari 520ST with TOS 1.00 and a 1040ST with TOS 1.04, although you can use your own ROMs. The emulator support TOS 1.00, 1.02, 1.04 and 2.06, up to 14MB of RAM, and can emulate all 3 video modes (though not all border effects), floppy drives, up to 7 hard disks, the serial and parallel ports, a mouse, a keyboard, and output MIDI to a standard MIDI file. At the time of writing, sound was not yet supported. Source code is available and licensed under the GNU General Public License.

Gemulator 9 Community Release and Xformer (Windows, MSDOS)

Gemulator is an open source Atari 520ST and 1040ST emulator for Windows. It can emulate the 68000, 68010, 68020, 68030 and 68040 processors and the 68881/68882 floating point co-processor. It supports compatible Atari ST and STE TOS (versions 1.0, 1.2, 1.4, 2.06), as well as MagiC, KaosTOS, and the open source EmuTOS, and can emulate a printer, modem, sound, joystick, 720K and 1.44M floppy disk drives (Atari formatted, of course), SCSI hard disks (Atari formatted), 512K to 14M of emulated memory, ST Low (320x200 16-color), ST Medium (640x200 4-color), ST High (640x400 monochrome), 800x600, 1024x768, 1280x1024, and 1600x1200 graphics, mouse, keyboard, etc. It can also emulate the Apple Macintosh II, IIci and Quadra (although if that's your interest, you may want to see the main Apple Macintosh emulators page). Old versions can even run on MS-DOS, although those versions have fewer features.

Also on that page is Xformer which emulates Atari 800, 800XL and 130XE. Different versions are available for Windows and MS-DOS.

Atari800 (Windows, Mac OS X, Linux, MSDOS, WinCE, Amiga, etc)

Atari800 emulates the Atari 800, 800XL, 130XE and 5200. It is intended to be a portable Atari emulator, and supports a variety of host platforms, including Windows, Linux, Mac OS X/PPC, BeOS, MS-DOS, WinCE, Atari TT/Falcon, Amiga, etc. It runs Atari 400, 800, 600 XL, 800 XL, 130XE and 5200 games, supports 130XE compatible memory expansions, has cycle-exact 6502 emulation, NMI interrupts, scanline-based POKEY interrupts, and ANTIC and GITA emulation, has exact POKEY registers, is able to load Atari executable and BASIC programs directly, has support for the cassette recorder, printer, raw and CAS images, stereo emulation, supports joysticks, emulates (with the mouse) paddles, Atari touch tablet, Koala pad, light pen, light gun, ST/Amiga mouse, Atari track ball, and the Atari 5200 analog controller, maps the Atari serial ports to either your real serial ports or the net, ATR, XFD, DCM, ATR.GZ, and XFD.GZ disk image support, etc. You can save the current emulation state as well as take screen shots with the emulator. This is an open source emulator that is released under the GNU General Public License.

Atari800Win PLus (Windows)

Atari800Win PLus is an Atari 8-bit emulator for Windows. It can emulate the Atari XL/XE, 5200 and probably others. Features include the ability to map the keyboard to the Atari joystick (so that you can use the keyboard when a game requires a joystick), emulate paddles, the Atari touch tablet, Koala pad, light pen, light gun, Amiga/Atari ST mouse, Atari trak-ball, joystick using the mouse, configure the memory size of your emulated machine, mounting of floppy disks (.ATR) and cassette recorders (.CAS) images, etc.

Altirra (Windows)

This is an 8-bit Atari emulator for Windows, released by the author of a well-known video capture utility. It emulates the Atari 800/800XL/130XE. It is able to handle protected disk images, like the APE (.pro) and VAPI (.atx), and preserve the original copy protection. It comes complete with SIO (serial input/output) call acceleration and burst I/O with protected disks, which allows such disks to be booted quickly. The program is open source and is licensed under the GNU General Public License.
