Super Mario Bros 2
NES platformer · Free browser emulator · Mobile & desktop
Play Super Mario Bros 2 in your browser with a WebAssembly NES emulator. Pick Mario, Luigi, Peach, or Toad and climb through dream worlds with keyboard, touch, or gamepad.
Powered by EmulatorJS (WebAssembly NES core). On phones, rotate to landscape for the largest playfield and the on-screen controller.
Tap Play in the player to start. On phones and tablets, EmulatorJS shows an on-screen D-pad and A/B buttons after start. On desktop, use the keyboard map below.
How To Play
Super Mario Bros 2 (the US NES release) swaps stomp-focused platforming for pick-up-and-throw combat. Choose Mario, Luigi, Princess Toadstool, or Toad — each with different jump height and pull strength — then fight through Subcon by uprooting vegetables and hurling them at enemies.
This page runs the NES ROM in EmulatorJS with the same fceumm WebAssembly core as Super Mario Bros 1 and 3. Tap Play, then use keyboard on desktop or the built-in virtual D-pad and A/B buttons on phones.

These are EmulatorJS default mappings (same defaults as emubrowser). Open the in-player settings gear to rebind keys or show/hide the virtual gamepad.

Touch devices
Yes — it works on phones and tablets. EmulatorJS ships a built-in virtual gamepad that appears on touch browsers after the game starts. You get an on-screen D-pad plus A, B, Start, and Select. A custom D-pad overlay is not required.
Physical Bluetooth gamepads also work through the browser Gamepad API. If the virtual pad is hidden, use the gamepad icon in the emulator toolbar to toggle it.
