A Windows Forum report published October 5, 2026 describes an unofficial Super Mario Bros. Wonder demo running on Windows without a conventional emulator. The project is not publicly downloadable, its implementation and performance have not been independently verified, and Nintendo’s reaction is unknown. Nintendo officially lists the game for Nintendo Switch.
What the reported Windows demo does
Windows Forum says a developer using the name Belmante demonstrated the game on Windows using static recompilation of its code and a graphics layer that translates NVN to Vulkan. The report characterizes this approach as running natively on PC rather than using a conventional emulator. Those technical details are attributed to the report and developer; the project’s code and implementation have not been independently examined. Windows Forum’s October 5, 2026 report

How well did it run?
The report says the demo ran at approximately 60 frames per second on one laptop with an RTX 3050. That is a reported result for a single demonstration, not an independently verified benchmark or a prediction of performance on other PCs. The same report notes minor graphical glitches and occasional frame-rate drops. Windows Forum
Can you download the PC port?
No public download is reported. The project repository is private, and the report gives no release date. Without access to the demo or repository, readers cannot reproduce the demonstration or assess compatibility on their own hardware. Windows Forum and its related report

Is Super Mario Bros. Wonder officially available on PC?
No. Nintendo’s official pages list Super Mario Bros. Wonder for Nintendo Switch and offer a physical edition; the Nintendo Store lists its release date as October 20, 2023 and names Nintendo as publisher and developer. The unofficial Windows demonstration is not an announced PC release, and buying the Switch game does not provide access to it. Nintendo’s official game site · Nintendo Store listing
Nintendo Support lists version 1.2.1, released April 15, 2026, with adjustments and fixes for the Nintendo Switch 2 Edition. That update information concerns the official console version, not the Windows demo. Nintendo Support update history

Has Nintendo responded?
The claim that Nintendo “probably isn’t happy” is speculation. The available reporting establishes no Nintendo response or action concerning this specific project, so the company’s reaction is unknown.
What the report does—and does not—establish
- Reported: a Windows demonstration described as using static recompilation and NVN-to-Vulkan translation.
- Reported, not independently measured: approximately 60 FPS on one RTX 3050 laptop, alongside glitches and occasional drops.
- Not established: public availability, a release schedule, reproducible performance, broad hardware compatibility, or independent verification of the code and implementation.
There are no verified public PC builds to compare. The report also does not establish how any future distribution would handle copyrighted game files. Treat the story as an account of a private demo, not as a downloadable port or a confirmed PC launch.
