Super Mario World Remastered Plus Guide

Super Mario World Remastered Plus needs an original standalone Super Mario World SNES ROM.

Do not use Super Mario All-Stars + Super Mario World, Super Mario Advance 2 ROMs.

What You Need​

  • Super Mario World Remastered Plus installed in Xbox Dev Mode
  • Your own legally dumped Super Mario World SNES ROM
  • Xbox Device Portal access

First Launch​

Launch the game once before uploading the ROM.

The game will tell you that the ROM needs to be placed in the game’s LocalState folder and renamed to:

baserom.sfc

Close the game after this message appears.

Uploading the ROM​

Rename your Super Mario World ROM to:

baserom.sfc

Open Xbox Device Portal and go to:

User Folders > LocalAppData > Super Mario World Remastered Plus > LocalState

Upload baserom.sfc directly into LocalState.

The final layout should be:

LocalState
└── baserom.sfc

Do not put the ROM inside a folder.
