Version 4.1.0 (2019/04/13)
Atari800 now includes Altirra BIOS-es for all emulated systems: 400/800,
XL/XE, and 5200; as well as Altirra BASIC. It is now possible to use the
emulator without providing any ROM images.
The Altirra OS-es and Altirra BASIC can now be selected by users in the
"System settings", if they want to use them. Previously Altirra OS was used
automatically only when no other OS ROMs were found.
joyhat support for all four real joysticks, configurable in CLI/cfg/TUI
All documentation specific to building Atari800 on Windows has been moved
from DOC/INSTALL to a new file, DOC/BUILD.windows. This document
has also been expanded with a new chapter covering building Atari800 using
Ability to use the built-in EmuOS firmware has been removed. Users wishing
to run Atari800 without providing OS ROMs now have an option of using the
built-in Altirra OS-es, which are compatible with much more Atari software
At the same time, it is still possible to compile a version of Atari800
without any OS ROMs built in, by means of the --disable-altirra_bios
Port specific improvements:
== Atari Falcon ==
- More Videl/screen handling fixes
- Ability to run Atari800 in an AES-less environment
- Replaced C2P with MMU friendly and faster code
- Atari800 should run on all TOS clones with XBIOS Sound API
== Android ==
- Fixed building of the Android target, broken in the previous release.
- Fixed labels on console keys (unreadable on hi-res displays)
- Fixed console keys press detection
- Fixed "right-handed joystick" trigger press
== Raspberry Pi ==
- updated build documentation
- find proper Broadcom GLes libraries
- fixed bug in GRAPHICS 9 (shifted colors)
== MS Windows ==
- updated build documentation
- updated build documentation
- it is possible to build atari800 out of source tree
- unconnected host joysticks initialized properly, fixes the MULE game
Atari800 emulator version 4.0.0
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 (please see DOC/CREDITS). This program is copyrighted and
released under the GPL (see COPYING).
Please read DOC/README, DOC/INSTALL and DOC/USAGE.
For news in this release please do read DOC/NEWS.
If you have a problem running this emulator please read DOC/FAQ first.
If the problem persists then please ask in newsgroup comp.sys.atari.8bit
or in the atari800-users mailing list (see below).
Look at DOC/BUGS before reporting something you consider a bug.
If you want to help developing Atari800 emulator you can subscribe to our
mailing list (http://lists.sourceforge.net/lists/listinfo/atari800-users).
DOC/TODO might point you in the right direction.
This version, and all versions back to 0.8.2 have been released by me (Petr
Stehlik) and are now available at Sourceforge.net (URL below). Thanks

Atari800 version 3.0.0 (released on 2013/03/03)
- Option to automatically save configuration on exit
- More settings saved in configuration:
- currently attached tape file
- cartridge settings, including currently attached cartridges
- state of R-Time 8
- system settings, including Mosaic/Axlon RAM size
- New Tape Management menu - can now create blank tape images, switch tape
to read/write in order to save additional data at the end of the current
tape image, rewind/fast forward the tape, and mark it as read-only. See
DOC/USAGE for details.
- Displaying tape position when "Show sector/block counter" is enabled.
- Reworked Cartridge Management menu - now displays filename of the
- Option to disable restarting of the machine after cartridge change.
- When attaching a cartridge from the command line, cartridge type can now
be specified using the new -cart-type and -cart2-type options.
- New cartridge types supported:
- OSS 8 KB cartridge
- OSS two chip 16 KB cartridge (043M)
- Blizzard 4 KB cartridge
- AST 32 KB cartridge
- Atrax SDX 64 KB cartridge
- Atrax SDX 128 KB cartridge
- Turbosoft 64 KB cartridge
- Turbosoft 128 KB cartridge
- Ultracart 32 KB cartridge
- Low bank 8 KB cartridge
- SIC! 128 KB cartridge
- SIC! 256 KB cartridge
- SIC! 512 KB cartridge
- Standard 2 KB cartridge
- Standard 4 KB cartridge
- Right slot 4 KB cartridge
- The configure script can now auto-detect some of the available display and
sound interfaces before compiling.
- Option to enable XEP80 added to The Emulator Settings menu.
- Emulation of the 1200XL, including console LEDs, no built-in BASIC, the
F1-F4 keys (mapped to arrow keys in the SDL version) and the on-board
- Emulation of the XE Game System, including the built-in game and
- Revamped the Select System menu (now called System Settings). Can now
select many system settings, including RAM expansions, OS and BASIC
revision, and more.
- System ROM settings moved to a separate menu. Now it stores paths to all
known official revisions of the Atari OS, the 5200 BIOS, all BASIC
revisions, and the XEGS built-in game. The OS revision to use is chosen
automatically when selecting a machine type (for example, the 400/800 OS
PAL or NTSC version is chosen depending on the selected TV system).
- 400/800: Emulation of all RAM sizes achievable with different combinations
of the CX852 and CX853 modules - from 8 to 48 KB.
- Emulation of 32/48KB memory sizes in the XL/XE mode, compatible
with memory expansions for the 600XL manufactured by RC Systems.

- Added new dialog for cartridge type selection
- UI fine tuning
- Bugfixes in cassette emulation - works reliably even for tape images with
long (> 4096 B) blocks.
- Fixes in save states - loading of save states works correctly even with an
attached bank-switched cartridge or with an Axlon/Mosaic RAM expansion.
Note 1: Format of the state files has changed. Old save states can still
be opened, but newly-created ones cannot be opened in older versions of
Note 2: Tape position is not restored on loading of save states. Do not
save state during tape loading/saving - it won't work as expected.
- "Disable BASIC when booting Atari" no longer emulates pressing of the
Option key when in the 400/800 mode.
- Fixed a bug with BASIC sometimes disabling itself when switching system
type to 400/800

- SDL version: Swapped mapping of right and middle mouse buttons, to make it
identical to the X11 and Win32 ports.

can be debugged.
- SDL version: fixed a blue border when in OpenGL BGRA32 mode.
- Minor fixes in parsing of command-line options.
- Rewritten XEP80 emulation - now more accurate and supports switching
between NTSC/PAL modes with correct aspect ratio. XEP80 emulation now
requires a charset ROM image, path to which should be set in the
XEP80_CHARSET line in the config file.
- Fixed operating system patches not working with all official revisions of
- Fixed emulation of separate ANTIC/CPU access to XE RAM when Self-Test is
- Fixed the emulator menu sometimes being displayed incorrectly (missing
