Yes. Absolutely. Whether you own the game on cartridge or digitally from the eShop, updating to version 1.0.3 is mandatory for a stable experience. The "NSP update" scene is a dangerous detour for a free, legitimate patch.
If you are searching for "the mummy demastered switch nsp update eshop upd" because you cannot access the official eShop (due to a banned console or region lock), your only safe recourse is to buy the game legally. The game is frequently on sale for under $10 USD. At that price, the peace of mind—and the ability to enjoy the eerie, pixelated corridors without crashes—is well worth it.
Final Rating for the Updated Switch Version: 8.5/10
The Mummy Demastered, patched to 1.0.3, is one of the finest metroidvanias on the Switch. Just get it from the eShop, not from a shady NSP link.

The Mummy Demastered has received a major optimization update on the Nintendo Switch eShop.
The 16-bit-style Metroidvania from WayForward—based on the 2017 film—faced initial criticism regarding its punishing corpse-run mechanic and late-game performance issues. This official software update addresses those complaints directly to create a much smoother experience.
The following guide breaks down the patch notes, how to safely update the game, and the impact it has on the digital installation files. 📜 Official Patch Notes the mummy demastered switch nsp update eshop upd
The developer rolled out a substantial patch targeted at QoL (Quality of Life) and overall game balance.
Performance Boost: Severe frame rate drops during late-game combat have been ironed out.
Faster Load Times: The initial boot-up and screen-transition times are drastically reduced.
Rebalanced Death Mechanic: The game’s notorious "Dark Souls" style death mechanic has been tuned. Undead agents (your former corpses) now have fairly balanced health based on the gear they hold.
Full Health on Recovery: Health packs reclaimed from your former undead self will now default to full rather than spawning you in at critical health.
Combat Tuning: Boss HP and the spawn frequency of annoying minor enemies like ravens and bats have been rebalanced.
HD Rumble: The Switch edition now natively features immersive HD Rumble support. 🛠️ How to Update via Nintendo eShop Have you updated your copy of The Mummy Demastered
Whether you own the official eShop digital version or are looking to tie the update file to an existing system backup (such as an .nsp file), applying the update is straightforward. Method 1: Automatic Internet Update Ensure your console is connected to the internet. Highlight The Mummy Demastered icon on your HOME menu.
Press the + (Plus) button on your Joy-Con to open the options menu. Select Software Update and click Via the Internet. Method 2: Manual Update via NSP File (For Modded Consoles)
If you are managing your library via custom firmware backups (NSP files) and need to update your game manually:
Obtain the specific Update NSP file corresponding to the latest version of The Mummy Demastered.
Ensure the Title ID of the update matches your base game region (US, EU, or JPN).
Use a homebrew title manager (such as DBI or Tinfoil) to install the update NSP on top of your existing game.
Do not delete your original base game NSP; updates only overwrite the necessary system files, not the game itself. ⚠️ File Size & Precautions Which of those would you like
File Size: The base game is roughly 785 MB, with the update patch adding a marginal amount to the total footprint.
Save Data: Updating through official channels or authorized title managers will not erase your save progress. Your cloud saves remain backed up if you have an active Nintendo Switch Online membership. The Mummy Demastered Just Got A Large New Update
