Punch-Out ROM Hack Creator v1.0.0

Make your own version of Mike Tyson’s Punch-Out!! (NES): change the boxers, what they say, Little Mac’s power and two-player controls, then save it to play.

  1. Load your game

    Drag your Punch-Out!! ROM onto this box, or find it in your files. It stays in your browser and is never uploaded.

    No ROM loaded
  2. Make it yours

    Change whatever you want: pick a preset on Home, or edit the boxers, Little Mac, the Randomizer and more in the tabs on the left.

  3. Play it or share it

    Play it now right here, with sound and a controller. Just for you: save the new ROM for your emulator. To share your creation: save the BPS patch and send it to a friend.

    1. Open Rom Patcher JS, a free site that works right in the browser.
    2. Pick their own copy of Mike Tyson’s Punch-Out!! (NES, US) as the ROM file.
    3. Pick your .bps file as the patch, then press Apply patch.
    4. Play the new file on an emulator or a flash cart.
