Super Mario Bros.: Sonic the Hedgehog is a ROM hack for the Nintendo Entertainment System that substitutes Mario with Sonic the Hedgehog while maintaining the original gameplay. In this version, Sonic runs continuously without player input. All text references have been altered to feature Sonic, and Toad now provides gameplay tips. The hack requires the Lunar IPS tool to apply to a Super Mario Bros. ROM.
