A new server you create. It is not this listing's official endpoint. Use the publisher install when you want their URL and their credentials.
LancerGearsystem is a very accurate, cross-platform Sega Master System / Game Gear / SG-1000 emulator written in C++ that runs on Windows, macOS, Linux, BSD and RetroArch, with an embedded MCP server for AI debugging and development.
This is an open source project with its ongoing development made possible thanks to the support by these awesome backers. If you find it useful, please consider sponsoring.
Don't hesitate to report bugs or ask for new features by opening an issue.
Notes:
brew trust --tap drhelius/geardomelibsdl3None in the Emulator menu. This emulates a machine without any media plugged in.Top+Bottom and Aspect Ratio Standard (4:3 DAR) in the Video menu. Game Gear will ignore any overscan settings.--portable, or create an empty file named portable.ini in the same directory as the application binary. On macOS, place the file next to the .app bundle.Link Cable in two desktop instances, select the same session, and connect both, or start each process with --link-session N. Select Auto, Gear-to-Gear, or Mark III under Protocol; the session is independent of this selection. Auto uses Gear-to-Gear for native Game Gear software and Mark III Joy-Joy for F-16 Fighting Falcon (Japan). For Mark III, Return, 1, 2, and Space are mapped to the SK-1100 keyboard. Reset the console if Mark III hardware is attached after startup. Independent instances should use separate application copies or --portable data directories so configuration, saves, and single-instance handling do not conflict.Emulator menu. When enabled, opening a ROM while another instance is running will send the ROM to the running instance instead of starting a new one.path_to_rom_file.sms it tries to load path_to_rom_file.sym. You can also load a symbol file using the GUI or the CLI. It supports sjasmplus/Pasmo (EQU), SDCC/NoICE (.noi), wla-dx and vasm/generic file formats.gearsystem [options] [rom_file] [symbol_file]
Arguments:
[rom_file] ROM file: accepts ROMs (.sms, .gg, .sg, .mv) or ZIP (.zip)
[symbol_file] Optional symbol file for debugging
Options:
-f, --fullscreen Start in fullscreen mode
-w, --windowed Start in windowed mode with menu visible
--mcp-stdio Auto-start MCP server with stdio transport
--mcp-http Auto-start MCP server with HTTP transport
--mcp-router Enable compact MCP tool routing
--mcp-http-address A HTTP bind address (default: 127.0.0.1)
--mcp-http-port N HTTP port for MCP server (default: 7777)
--headless Run without GUI (requires MCP or Link Cable)
--link-session N Connect to link cable session 1-255
--link-stall-us N Override barrier stall threshold (0=default)
--portable Store configuration and user data beside the application
-v, --version Display version information
-h, --help Display this help message
Gearsystem includes a Model Context Protocol (MCP) server that enables AI-assisted debugging through AI agents like GitHub Copilot, Claude, Codex and similar. The server provides tools for execution control, memory inspection, breakpoints, disassembly, hardware status, and more. STDIO and HTTP transports are supported, with STDIO preferred.
For complete setup instructions and tool documentation, see MCP_README.md.
Gearsystem provides Agent Skills that teach AI assistants how to effectively use the emulator for specific tasks:

If you are using Ubuntu 26.04, you can install SDL3 directly. Use the following commands to build:
sudo apt install build-essential pkg-config libsdl3-dev libgl-dev
cd platforms/linux
make
For Ubuntu 24.04, you need to build SDL3 from source first. Use the following commands to build both SDL3 and Gearsystem:
sudo apt install build-essential cmake git curl jq pkg-config \
