FCEUX is an all-in-one NES, Famicom, and Famicom Disk System (FDS) emulator that has become the gold standard for both casual players and the Tool-Assisted Speedrun (TAS) community. On Linux, FCEUX provides a robust experience through its modern Qt-based interface, offering cross-platform parity with its Windows counterpart.

Depending on your Linux distribution, you can install FCEUX via official repositories, universal packages like Snap, or by building from the source for the latest features.

Most major Linux distributions include FCEUX in their default package managers.
