atari800 (Atari 8-bit computer emulator)

This is a free and portable Atari 8-bit computer and 5200 console
emulator, originally written by David Firth and now developed by the
Atari800 Development Team. This program is copyrighted and released
under the GPL.

This build uses SDL for audio, and SDL+OpenGL for video by default. To
build without OpenGL support (SDL software rendering only), set OPENGL=no
in the script's environment.

Starting with version 4.0.0, atari800 includes free replacements for the
system ROMs, from the Altirra project. This allows you to run most Atari
software without installing the original ROMs. However, for maximum
compatibility, you'll need the Atari system ROMs. These are packaged
on SBo as atari800_roms. After installing the ROMs, use the built-in
menu in atari800 to set the paths (/usr/share/atari800/atari800_roms/*)
and disable the built-in Altirra ROMs.

When upgrading to 4.0.0, if the Atari's display is 'washed out' (too
bright), remove your old "~/.atari800.cfg".
