Missingno is an emulator for the Game Boy, Game Boy Color, and Atari VCS (2600). It is built around faithful models of the original hardware: games look, sound, and behave as they do on the real machines, with display options that recreate the look of the original LCD and CRT screens.
The library manages your collection: cover art and metadata are fetched automatically, play sessions and screenshots are recorded, and saves are managed and backed up. Homebrew games can be browsed and downloaded from Homebrew Hub, and physical cartridges read and written with a GBxCart RW.
The integrated debugger works across every supported system, with disassembly, breakpoints, and live inspection of CPU, video, and audio state.
