FlawlessNES

Beat the NES.
Prove it.

FlawlessNES turns retro NES games into bite-sized challenges with verified completions and live leaderboards. Run them in BizHawk; your scores ping the board the moment you win.

Same Google account works across the desktop app and web — your stats follow you.

  • Curated NES challenges

    Boss fights, speedruns, score targets, survival gauntlets — each one a tight scenario you can pick up and run in a couple of minutes.

  • Verified completions

    Win conditions read directly from emulator RAM. No screenshot uploads, no honor system. The challenge fires complete the instant you actually win.

  • Time-first leaderboards

    Every challenge ranks by completion time. Score breaks ties. The fastest legitimate run wins — no exceptions.
