Missingno – Game Boy emulator and debugger

Missingno is a Game Boy emulator and debugger written in Rust.

The software is geared not just toward playing games, but also toward hardware-accurate emulation, cartridge preservation, and library management. It includes tools for working with physical cartridges through compatible hardware, alongside a modern desktop interface for organizing games, tracking activity, and inspecting low-level emulator state.

This is free and open source software.

Key Features

• Integrates a built-in debugger with code disassembly, breakpoints, CPU state inspection, VRAM visualization, audio channel inspection, and interrupt viewing.
• Manages a game library with automatic cover art, play history tracking, and save management.
• Supports keyboard and controller input, fullscreen mode, and multiple display palettes.
• Reads ROMs and save data from physical cartridges when used with a GBxCart RW device.
• Offers hardware-focused emulation with continued accuracy improvements for the Game Boy display and audio subsystems.
