Reported Switch 2 Game Ports Show the Compromises of Running on Original Switch

A developer has reportedly demonstrated Mario Kart World and Pokémon Pokopia running on the original Nintendo Switch, offering an unusual example of the experiments emerging around Switch 2 modding. According to Wccftech’s November 3 report, X user @touhoufagyuri shared videos of both games, although the code is being withheld.

The demonstrations come with substantial qualifications: both reportedly use an overclocked console, and the footage does not establish how either project would behave throughout a complete playthrough.

Getting the games running required trade-offs

For Mario Kart World, Wccftech describes a progression from barely running to a more playable demonstration. Reported changes include prebaked shaders, forced level-of-detail settings, reduced resolution and other unspecified optimizations. Stuttering remains visible, according to the report, while substantial portions of the free-roam experience have been cut down.

Pokémon Pokopia reportedly required a reduction to 720p. Wccftech says the developer’s 1080p configuration delivered only 10–15 frames per second. A subsequent 30fps cap reportedly addressed uneven frame pacing seen when performance hovered around 35fps. Those figures describe the reported demonstrations; they do not establish consistent performance across the game.

Display-only projects, with no public code

Wccftech attributes the lack of a public release to the developer’s stated legal concerns. The developer describes the projects as demonstrations and directs people to purchase the official games.

For followers of Switch 2 homebrew and modding, the footage’s interest lies in the technical compromises involved. It should be treated as a limited demonstration rather than evidence that these games can reliably replace their official versions on older hardware.
