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. Multi-language support (12 languages) and a full suite of debugging and TAS tools are built in for developers and speedrunners alike. Whether you're revisiting childhood classics or diving into ROM hacking, FCEUX11 runs your NES games smoothly and looks great doing it.

Features

  • Accurate Emulation: Full NES, Famicom, and mapper support with faithful graphics and audio, delivering the authentic 8-bit experience.
  • Save States: Save and load anywhere, anytime, with automatic state history so you never lose progress.
  • Cheats: Game Genie and raw cheat code support to tweak gameplay, unlock hidden content, or just have fun bending the rules.
  • Movie Recording: Record full playthroughs, replay them anytime, and export to AVI to share your best runs.
  • Gamepad Support: Play with keyboard or gamepad, with fully remappable inputs to suit your play style.
  • Multi-language UI (v1.11 upgrade): v1.11 (Bridge) expands the available UI languages from 3 to 12 — 简体中文、繁體中文、English、日本語、한국어、Español、Français、Deutsch、Tiếng Việt、ไทย、हिन्दी(beta)、العربية(beta). On first launch the language is auto-detected from your system locale (zh-CN / ja-JP / ar-SA, etc.), and menus/dialogs are fully retranslated the moment you switch. Arabic automatically enables right-to-left layout.
  • Custom Palettes: Load custom palette files to fine-tune color rendering and match the exact look you remember.
  • Debugging Tools: Built-in CPU/PPU debugger, hex editor, RAM search/watch, and code/data logger for ROM hacking and in-depth analysis.
  • TAS Editor: Frame-by-frame recording and precise input editing to craft perfect Tool-Assisted Speedruns.
  • Lua Scripting: Write Lua scripts to create custom on-screen displays, automate gameplay, or read memory, extending the emulator however you like.
