The official update for The Mummy Demastered on Nintendo Switch Go to product viewer dialog for this item.

The Switch will contact Nintendo’s servers, compare your installed version to the latest available, and download any missing patches. As of 2025, the most current version for The Mummy Demastered is version 1.0.3 (though always check for newer).

Digital Store: Available on the Nintendo eShop for approximately £17.99 / $19.99 (prices often drop during sales).

When WayForward released The Mummy Demastered alongside the ill-fated 2017 Tom Cruise film, few expected it to become a modern Metroidvania classic. However, years later, it remains a staple for Nintendo Switch owners. Whether you are looking for the latest eShop update, managing your NSP files, or wondering how the game performs after its major technical patches, this guide covers everything you need to know about keeping your version up to date.

Check your Purchase History in the Nintendo Account portal to verify ownership.

For Nintendo Switch owners, the game became a cult favorite, but like many digital titles, it required post-launch polish. This brings us to the specific, often searched terminology regarding its digital lifecycle: the NSP update and the eShop upd (update) process.

The Switch version launched alongside other platforms but received several post-launch patches to address framerate dips and loading times—common issues in the original release.

Important: Installing an update NSP that is not signed for your console (i.e., downloaded from the internet) requires sigpatches. Without them, the Switch will refuse to launch the updated title. Additionally, connecting to Nintendo’s servers with a modified console can lead to a ban. Use DNS blocking (like 90DNS) or keep the console in airplane mode.

However, if you are a homebrew enthusiast managing your own backups, understanding the NSP update process is valuable—just remember to source files responsibly and never connect a pirated copy to Nintendo’s online services.
