Felix vs Javatari

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.

Javatari is a free Atari 2600 emulator designed for the Web. Users can load cartridges in a browser, with ROMs opened from local storage, iCloud, Google Drive, Dropbox or web links. It runs in browsers tested with Chrome, Firefox and Safari, and can be installed as a WebApp on iOS, Android or desktop for offline play. Savestates can be exported and shared. Playback controls include adjustable speed, pause and frame-by-frame advance; display tools include resizing, fullscreen, screen capture and debug modes. Customizable joysticks, joykeys and touch controllers are available, with haptic feedback on mobile. NetPlay lets multiple users connect to and control one virtual console over the internet, although it does not work on Apple iOS because required WebRTC technologies are unavailable there. Performance depends on network quality. A JavaScript API supports ROM loading and console control, and games can be embedded in webpages or launched with a Javatari page link. The project repository identifies the software as licensed under AGPL-3.0.
