Atari800MacX vs Felix

Atari800MacX is a free macOS application that emulates Atari 8-bit computers and the Atari 5200. It supports the Atari 400/800, 1200XL, XL/XE, XEGS and Atari 5200 systems, with cartridge and machine support, joystick input, full-screen or windowed display and hard-drive emulation. Save states and controller remapping are supported. A native Cocoa interface supplies preferences, menus, file associations and help, while libSDL is bundled in the application package. The emulator needs ROM image files from original Atari systems; those files are not included. Version 6.0.1 is the latest release listed, dated January 22, 2022, and requires OS X 10.12 or newer. Version 6.0.0 added support for ARM-based M1 Macs. Listed updates include synchronized sound, a graphical debugger, VAPI and PRO images, copy and paste, configuration files and a new hard-drive emulation scheme. Downloads include the application and source code. Development is described as sporadic due to work commitments.

Felix is a free Atari Lynx emulator distributed as a public GitHub repository under the MIT license. It currently builds only under Windows, with documented build routes through Visual Studio 2022 or command-line CMake; both require Visual Studio 2022, Git, and CMake. The README says it is expected to work in Wine, Parallels, and similar environments. Version 0.5.0 introduced a simple graphical interface, redefinable key mapping, and basic gamepad support. Release notes also list Lua debugging facilities, a monitor window, and commands for dumping WAV and VGM audio. Lua libraries for string, os, math, and table are included. The latest listed release is 0.6.4. Known issues in version 0.6.0 include hangs in Awesome Golf and Scrapyard Dog, crackling from audio/video synchronization, and debugging features that remain imperfect. The project is maintained through the laoo account, whose profile names Waldemar Pawlaszek and lists Wrocław.
