What Felix is

Felix is a free Atari Lynx emulator for Windows, with a simple graphical interface and support for redefining keys and using a gamepad. Its feature set also includes Lua debugging facilities and a monitor window. Audio commands can dump WAV and VGM files, and Lua libraries cover string, os, math, and table functions. The public GitHub repository identifies the project under an MIT license, and the latest release listed is version 0.6.4.

Felix currently builds only under Windows. The README says it is expected to work in Wine, Parallels, and similar environments. For a self-build, the documented options are Visual Studio 2022 or command-line CMake; either route requires Visual Studio 2022, Git, and CMake. Release notes also describe hangs in Awesome Golf and Scrapyard Dog, crackling related to audio/video synchronization, and debugging features that are not fully refined. The laoo GitHub account is maintained by Waldemar Pawlaszek, whose profile lists Wrocław.
