In 2015, a fan remake of "Super Mario 64" was created in Unity, called "Super Mario 64 HD". The project was later taken down due to a copyright claim by Nintendo. In 2019, fans decompiled the original ROM image into C source code, allowing the game to be unofficially ported to any system and run natively, rather than through emulation. The following year saw the creation of an unofficial Windows port, with support for widescreen displays and 4K visuals. Nintendo subsequently enlisted a lawfirm to remove videos of the ported game and its listings from various websites. A direct sequel tentatively titled "Super Mario 64 2" was planned for the Nintendo 64DD. In July 1996 Nintendo insiders stated that Miyamoto was assembling a team to work on a "Super Mario 64" sequel, consisting mostly of developers who had worked on the original "Super Mario 64". Miyamoto mentioned at E3's 1997 convention that he was "just getting started" on the project. In May 1999, "Super Mario 64 2" was reported to be released in late 1999; however, the game was canceled due to the commercial failure of the 64DD, as well as lack of progress in the game's development. Instead, "Super Mario 64" was followed by other 3D "Mario" games on subsequent Nintendo systems, such as "Super Mario Sunshine" for the GameCube and "Super Mario Galaxy" for the Wii. These games built on "Super Mario 64"s core design of enhancement items and open-ended gameplay. "Super Mario Galaxy 2" features a remake of "Mario 64"s Whomp's Fortress level. Later 3D games, namely "Super Mario 3D Land" and "Super Mario 3D World", while keeping many of "Super Mario 64"s core gameplay elements, departed from the game's open-ended design and focused more on platforming reminiscent of 2D games. The Nintendo Switch game "Super Mario Odyssey" returns to "Super Mario 64"s open design.
