The Super Mario Bros. Movie 64 DS

New Super Mario Land is a recreation of Super Mario Land (Game Boy) using New Super Mario Bros. (Nintendo DS) assets and released for the SNES, with pseudo-3D graphics and a new co-op multiplayer mode.

This is a complete hack of Super Mario World. Don't expect any new graphics here; this game is all about the level design. All the levels and worlds are new, and some of the worlds have themes not present in the original game, such as a water world and an ice world.

Released in 2022 on PlayStation, by Mauk 696.
