Atari800 is a free Atari emulator written in C. It was also the name of one of the computer models it emulates, which can make references a bit confusing.

Hardware emulated

• Atari 400, 800, 600 XL, 800XL, 130XE, 5200 Games System.
• 130XE compatible memory expansions: 320K, 576K, 1088K.
• Optional 4K RAM between 0xc000 and 0xcfff in 400/800 mode.
• Cycle-exact 6502 emulation, all unofficial instructions.
• Cycle-exact NMI interrupts, scanline-based POKEY interrupts.
• Cycle-exact ANTIC and GTIA emulation, all display modes.
• Player/Missile Graphics, exact priority control and collision detection.
• Exact POKEY registers (sound and random number generator).
• 8 disk drives, emulated at computer-to-drive communication and fast patched SIO levels.
• ATR, XFD, DCM, ATR.GZ and XFD.GZ disk images.
• Direct loading of Atari executable files and Atari BASIC programs.
• 42 cartridge types, raw and CART .
• Cassette recorder, raw and CAS images.
• Printer support.
• Files can be stored directly on your host computer via the H: device.
• Current emulation state can be saved in a state file.
• Sound support on Unix using "/dev/dsp".
• Stereo (two POKEYs) emulation.
• Joystick controller using numeric keypad.
• Real joystick support.
• Paddles, Atari touch tablet, Koala pad, light pen, light gun, ST/Amiga mouse, Atari trak-ball, joystick and Atari 5200 analog controller emulated using mouse.
• R-Time 8 emulation using host computer clock.
• Atari palette read from a file or calculated basing on user-defined parameters.
• Screen snapshots (normal and interlaced) to PCX and PNG files.
• Sound output may be written to WAV files.
• User interface on all versions supporting bitmapped graphics.
• R: device (the Atari850 serial ports) mapped to net or real serial port.
