Developer's Description

Atari800 emulator was written by David Firth in 1995 and released under the GPL. So it was available with full source code in C. The code was written with portability in mind and that allowed various people to create ports of Atari800 for PC, Amiga, Atari, Mac and machines running UNIX-like operating systems.
As there were no new versions of Atari800 since spring of 1997 several people (Perry McFarlane, Rich Lawrence, Thomas Richter, Radek Sterba, Robert Golias and Petr Stehlik) started updating the last available v0.8.0 source code independently. Later we all got in touch and started working together. I also contacted the original Atari800 author, David Firth, who basically agreed with me maintaining the source code and putting out source and binary releases.
Since then many new talented programmers joined the Atari800 development team and helped improving the emulator.

Raspberry Pi port is officially supported from version 3.0.0.

Note: you need to setup correct video mode for PAL/NTSC machines (proper video/audio sync and vsync).
edit /boot/config.txt

for PAL version (50 Hz) you can supply this values:
720p mode:
hdmi_group=1
hdmi_mode=19
1080p mode:
hdmi_group=1
hdmi_mode=31

for NTSC version (60 Hz):
720p mode:
hdmi_group=1
hdmi_mode=4
1080p mode:
hdmi_group=1
hdmi_mode=16
