⚠ Note: This is a fan modification. You need a legal copy of New Super Mario Bros. Wii to use it, as well as a homebrew-enabled Wii or Wii U.
What does mean in this context? Unlike a Switch game, Newer Super Mario Bros. Wii 130 is designed for a home console. But "portable" here refers to: newer super mario bros wii 130 wbfs portable
