Located at Jubilife Village’s Training Grounds, this mode lets you battle waves of wardens and trainers. It is the only way to rematch certain characters and obtain rare evolution items.

What is an NSP Update? (A Quick Primer)

Before diving into the specifics, let’s clarify the terminology. An NSP is a raw, unmodified dump of a digital game file directly from Nintendo’s servers. An NSP Update is a separate file that layers new data (DLC, patches, fixes) on top of the base game.

For Pokémon Legends: Arceus, the base game (usually labeled Pokemon Legends Arceus [BASE]) is unplayable at its v1.0.0 state without the Day 1 patch. Consequently, the NSP UPDATE is non-negotiable for a stable experience.

Installation Order for Emulators (Ryujinx / Yuzu) or CFW (Atmosphere/SX OS):

  1. Base Game: Load or install Pokemon Legends Arceus [BASE] [01001F5010DFA000].
  2. Update: Install Pokemon Legends Arceus [UPDATE] [v1.1.1] [01001F5010DFA800].nsp.
    • Note the slightly different Title ID for the update. The last digit changes from 0 to 8.
  3. DLC (Optional): There is no paid DLC for this game, but the "Daybreak" update acts as a free DLC. No separate unlocker is needed.
