Atari800 v6.0.0 is released. Atari800 is an Atari 800, 800XL, 130XE and 5200 emulator for Unix, Amiga, MS-DOS, Atari TT/Falcon, SDL and WinCE.

Atari800 Changelog:
New features:
SDL2 support — SDL2 is now the primary SDL target. Selected automatically
when both SDL1 and SDL2 are available. Includes:
OpenGL shader support and improved rendering
SDL2 controller button configuration (map buttons to actions, D-pad UI)
Correct keyboard handling (CAPS-Lock, control letters, HELP with modifiers)
NetSIO / FujiNet support — network SIO over UDP, enabling connectivity with
FujiNet devices. Supports high-speed divisors, PROCEED signal, port sharing
(SO_REUSEADDR), and Windows (Winsock2). Configurable port via -netsio_port.
Paddle controller support (SDL2-only):
New JOY_MODE_PADDLE mode on any Atari port
Per-port configurable pot axes and fire buttons
Config keys: JOY_PORT_{0-3}PADDLE_AXES, JOY_PORT{0-3}_PADDLE_BUTTONS
Joystick configuration reorganised by Atari port (SDL2):
Each of the four Atari ports can be independently assigned an input source
(None, Keyboard 1/2, host joystick, paddle, parallel port)
New config keys: JOY_PORT_{0-3}_{MODE,PARAM,NAME}
Host joysticks opened into a flat pool, assigned by name for persistence
Automatic smart defaults: if host joysticks are detected they are assigned
to ports; otherwise port 0 defaults to keyboard
Support for J(atar)Carts & DCart cartridge types
Alternative key mapping for Atari 5200 Bounty Bob Strikes Back!
Turbo speed selection and quick save/load state
libatari800 API extensions: mount_disk(), unmount_disk(), disable_drive(),
disk activity callbacks, SIO patch control
Monitor command enhancements: summaries and error codes added
Changes:
Sound system refactored:
VOL_ONLY_SOUND code removed (was unused and poor quality)
SYNCHRONIZED_SOUND and SOUND_THIN_API now forced on
SERIO_SOUND code removed
CPU emulation refactored for readability
Delayed NMI handling implemented per Altirra Hardware Reference Manual
SDL2: Removed -joy-distinct option (no longer needed with per-port assignment)
SDL2: Removed -joyswap / Alt+J swap joysticks shortcut
SDL: window stays open while using the monitor
SDL: joystick subsystem initialized only when needed
Falcon: -interlace parameter removed (use -refresh instead)
Falcon/FireBee: switched to m68k-atari-mintelf-gcc, usound routines
CAS/XFD detection order corrected
Host device letter input validation
Bug fixes:
Fix ATX handling on command line (bug since 2009, fixes #218)
Fix XF551 Get Status command (SuperDOS 5.1 timeout, fixes #190)
Fix Corina and other size-based BIN file loading (fixes #258)
Fix harmful typo in gtia.c (fixes #163)

SAF-based storage (no more FileSelector), Material Design icons,
high-DPI console key scaling, auto-rotation, notch/cutout support,
state save/load reworked, CMake/Gradle build system,
BT and USB joysticks supported (up to four).
