FCEUX11 is a derivative of the FCEUX NES/Famicom emulator, optimized for Windows. It inherits FCEUX's renowned emulation accuracy while delivering a polished, modern Windows-native experience powered by Qt6, with 12-language localization and a full suite of debugging and TAS tools for developers and speedrunners. Ongoing internal refactoring and performance optimization keeps the emulator efficient, smooth, and stable even under heavy load. Experimental Game Boy Advance (GBA) emulation support has been added, reusing the existing UI, save-state system, hotkeys and debugging infrastructure; GBA features are in Beta, the picture carries a watermark, and some hardware features are not yet fully implemented.
Features

- Experimental GBA Emulation (BETA): Play .gba cartridges with BIOS system calls, audio output, battery saves (.srm), save states, controller input, and integer-scaled display; the Beta watermark cannot be disabled.

- Movie Recording & TAS Editor: Record full playthroughs, replay them anytime, and export to AVI to share your best runs; frame-by-frame input editing helps you craft perfect Tool-Assisted Speedruns.
