Super Mario 3D All-Stars - Leaked Online | Nintendo Switch News | NintendoReporters

 [![Super Mario 3D All-Stars – Leaked Online](https://www.nintendoreporters.com/storage/files/super-mario-3d-all-stars-leaked-online.jpeg "Super Mario 3D All-Stars – Leaked Online")](https://www.nintendoreporters.com/storage/files/super-mario-3d-all-stars-leaked-online.jpeg)Super Mario 3D All-Stars, the collection of classic 3D Mario titles announced for his 35th anniversary, leaked online.

The news comes via well-known Nintendo Switch dataminer OatmealDome, who claims that the game has been dumped on the internet, just a few days before its official launch of September 18th.

## [](#emulated)Emulated

Although there aren’t that many spoilers to be shared, Oatmealdome did apparently manage to decipher a few interesting details about how the port was handled:

> Galaxy in particular is really interesting. It appears they recompiled the original code to run natively on the Switch CPU, but everything else (GPU/Audio) is running in the emulator.
>
> Interesting trick!

> Other minor tidbits…
>
> The project codename might be "Stardust". There also might be a sub-codename for Galaxy – "Shigeru".
>
> The menu that lets you choose games is made with LunchPack (engine used by Splatoon / Mario Maker / Animal Crossing).

Still I am looking forward to this release regardless.

But emulators … does this mean these in house emulators are going to offer something for Nintendo Switch Online?
