Gearlynx vs Holani

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.

Holani is a free, open-source Atari Lynx emulator for Linux and Windows, released under GPL-3.0. Its cycle-stepped 65C02S emulation began from the design idea of chips’ 6502. The project can also operate as a library for other frontends and links to a libretro core for official games and homebrews. Holani-retro works with libretro frontends such as RetroArch, providing save and load states plus RetroArch cheats. Holani-gtk is a GTK4 frontend for loading cartridges and overriding ROMs. Holani-min provides a command-line interface with button mapping, display filtering, mute, and Comlynx options; multiple instances can connect through Comlynx. The project also lists holani-debug, an Atari Lynx debugger. Holani embeds the Free Lynx Boot ROM and BLL uLoader blobs, so no BIOS is required. GTK builds require Rust, Cargo, and GTK4; Windows libretro use requires the Microsoft Visual C++ 2015 Redistributable.
