To confirm the update is working:

Highlight the game icon on the Switch dashboard.
Press the + (Plus) button.
Navigate to Manage Software -> Check for Update (if online) or simply look at the version number displayed on the screen.

Base NSP Title ID: 0100B0A00B604000 (US version) – Make note of this.

UPD v1.0.2 – Added full Vol.2 ROM set inside the update itself (unusual – updates normally don’t include gigabytes of game data). This allowed clever repackers to release a single "UPD + unlock" NSP.
UPD v1.0.3+ – Minor stability, leaderboard fixes.

The key takeaway: The update NSP for Arcade PAC is unusually large (1–2 GB) because it contains the actual arcade ROMs for both museums. The base NSP is just a shell (~200 MB).
