If you are running the game via an emulator like Yuzu or Ryujinx, or using custom firmware on hardware, the NSP format is often the most stable for applying patches.
To ensure the game works properly, you must install the official game update file (typically provided as an NSP).
The most common reason the "update work" fails is due to a mismatch between the base game file and the update file.
Skylanders Imaginators remains one of the most unique titles on the Nintendo Switch due to its hybrid "toys-to-life" mechanics. Unlike other platforms, the Switch version allows players to scan and store their physical figures directly onto the console for digital, on-the-go play.
