Gearlynx vs z26

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.

z26 is a free, open-source Atari 2600 emulator for Linux, macOS, and Windows. The maker lists version 4.07 as the current SDL2 and OpenGL release for those systems, with Windows and Macintosh executables plus source code. A separate DOS release is listed as version 1.58. Input support covers PC and USB joysticks, gamepads, mouse, and keyboard. A mouse or PC trackball can operate trackball and paddle games; mouse input is also documented for light-gun games, while keyboard input supports driving-controller games. z26 handles several cartridge bank-switching schemes, including standard 8K and 16K, Atari Super-Chip, CBS Ram Plus, and Pitfall II. Digital sound processing has low and high settings. Developer tools include trace mode, scanline counting, and controls for disabling individual graphics objects.
