Gearlynx vs kat5200

Gearlynx is a free, open-source Atari Lynx emulator and debugger written in C++. It supports the commercial Lynx catalog and most homebrew and demo software, with Lynx I or Lynx II emulation selectable. Supported ROM formats include lnx, lyx, o, bin, and zip, including compressed and homebrew files. Gaming tools include save states with previews, rewind, run-ahead to reduce input latency, audio emulation, VGM recording, and EEPROM and NVRAM save files. ComLynx multiplayer connects up to eight emulator instances on one computer. The debugger provides disassembly, CPU and memory breakpoints, debug symbols, memory editing and search, hardware register views, and cartridge and video inspectors. An embedded MCP server supports AI-assisted debugging, with execution controls, memory inspection, breakpoints, screenshots, and rewind over STDIO or HTTP. Standalone builds are listed for Windows, Linux, BSD, and macOS; libretro includes Android and iOS. Gearlynx requires a BIOS. Concurrent HTTP clients control the same emulator instance and may interfere with one another.

kat5200 is a free emulator for playing games from Atari 5200 and Atari 8-bit computer systems on a personal computer. It supports Atari 5200, Atari 400, Atari 800, Atari 800 XL and Atari 800 XE systems, with builds listed for Windows, macOS, Linux and Android. The emulator does not include game ROM images or BIOS files, so users must obtain and configure them separately. Controls can use a game controller, keyboard or mouse, and multiple input entries can be assigned to an emulated function. Users can save different input profiles and assign them to games in the Launcher. The Simulate Analog option can help when a game expects controller-axis positions but the player uses a keyboard or digital controller. Initial setup offers ROM-directory scanning and options for trackball, paddle and two-stick games. Version 1.0.0 uses TOML configuration and adds per-ROM profiles. The Android version is provided as an APK, not through the Play Store, and must be sideloaded.
