Tip: If you make a change to your ROM that you regret, just go to File > Restore > Restore ROM to Previous State in the menu. From there, you can select a restore point and revert your ROM to a previous state.

Super Mario World Hacks
Welcome to the hack archive of SMW Central. The BPS patches in the ZIPs are the hacks; to play the hacks, apply the patches to a clean, American Super Mario World ROM using Floating IPS. We do not provide ROMs here, nor do we link to them. For more information, see our FAQ or the forums.
