, you must manually install both the update and DLC files. Go to File > Install Files to NAND , then select your update NSP followed by your DLC NSP. Verify Add-ons:
After installation, right-click the game in your library and select Properties
. Ensure the boxes for the update and specific DLC packs (like the Character Pass or Gear 5 Luffy) are checked. Merging Files:
To simplify the process and avoid separate installs, you can use tools like NSC Builder Swiss Army Knife (SAC)
to merge the base game, update, and DLC into a single NSP or XCI file. Troubleshooting Common Issues Region Mismatch:
A frequent cause for DLC not "working" or appearing in-game is a region mismatch between the base game (e.g., US) and the DLC/update (e.g., EU). Both must share the same region code to function. Update Requirement: Many DLC characters, such as those in Character Pack 8
, require a specific minimum game update version to be recognized. Always install the latest update NSP before the DLC. Switch 2 Compatibility: Note that the Switch 2 Edition Upgrade
may not be compatible with original Switch online play, and some users have reported DLC packs (like Pack 8) not appearing on the newer console edition without re-downloading through the official store. Are you running this on original hardware with custom firmware or on a PC emulator like Ryujinx or Yuzu?
