Atari800 Installer for Linux

Use Atari800 Installer to download and build the latest source for Atari800, or to update Atari800 to its latest release version.

Atari800 is a cross-platform emulator with out-of-the-box emulation of the Atari 400, 800, 1200XL, 600XL, 800XL, 65XE, 130XE, 800XE, XE Game System, 5200 SuperSystem. Emulates Atari 1400XL and 1450XLD when their BIOS-es are installed.

Many Linux distros ship out-of-date Atari800 packages in their software repos. To get the most up-to-date and feature rich version of Atari800 we have to download and compile the source code. The new Atari800 Installer for Linux, released especially for lazy people like us, takes care of the download, configure, make, make install stuff for us.

Atari800 Installer downloads the most up-to-date stable version of Atari800 then compiles the code and installs an application icon.

The installer is menu driven. It is free. It is hosted here on Github. There is a nice screenshot below of the installer in action.

Version 4 of Atari800 ships with AltirraOS which means there is no longer a need to download the Atari BIOS-es packaged in X25 unless a specific Atari program refuses to run on AltirraOS, which is very unlikely. Our own tests suggest Atari800 with AltirraOS loads games perfectly well. We have not yet needed to revert to any other OS.

Atari800 Installer

Atari800 installer is a Linux BASH script that installs and updates the Atari800 package. Version 4 of Atari800 will use the BIOS-es defined in any previous installation’s configuration file. Any existing BIOS-es need to be unset if you want to use AltirraOS. The Installer includes an option to delete any existing Atari800 user configuration file to force Atari800 to run cleanly with AltirraOS.
