2. Platform and File Format Terminology

Conclusion

One Piece: Pirate Warriors 4 remains a fantastic musou title, and understanding NSPs, updates, and DLC is useful for archival or personal backup purposes. However, the phrase “exclusive” in piracy scene releases is rarely legitimate. For the safest, most complete experience—including online co-op and proper updates—purchase the game officially. If you choose to emulate, always follow the legal route: dump your own cartridge or digital purchase.

How Updates and DLC are Structured

If you acquire legitimate NSP/update/DLC files (by dumping your own purchased copy), they must be installed in order:

  1. Install Base NSP.
  2. Install Update NSP (latest version first – updates are cumulative).
  3. Install each DLC NSP (order usually doesn’t matter, but some require a minimum update version).

On emulators, you simply load the base NSP, then use the emulator’s “Install File” feature to add updates and DLC NSPs. On a modded Switch, you would use tools like Atmosphere + Goldleaf or DBI.

2.1. Understanding "NSP"

The term "NSP" stands for Nintendo Submission Package. It is the file format used by the Nintendo Switch operating system to install games, updates, and DLC.

  • Unlike a traditional "ROM" (Read-Only Memory), which typically refers to a dump of a cartridge (XCI format for Switch), an NSP file is essentially an eShop container.
  • An NSP file contains the game executable, assets, and metadata required for the Switch to recognize and play the software.

What is an NSP?

In the Nintendo Switch scene, NSP stands for Nintendo Submission Package. It is a file format used for digital games, updates, and DLC directly from the Nintendo eShop. An NSP contains the exact data that would be installed to a Switch’s internal memory or SD card.

  • Base Game NSP – The core game files (e.g., One Piece Pirate Warriors 4.nsp).
  • Update NSP – Patch files (e.g., v1.2.0, v1.3.0, v1.4.0) that add features, fix bugs, or enable compatibility with newer DLC.
  • DLC NSP – Additional content packs (characters, scenarios, costumes) that are locked behind purchase keys.

These files are commonly used with PC Switch emulators such as Ryujinx (now discontinued but still in circulation) or Yuzu (also discontinued). Some users also install them on modded (custom firmware) Switch consoles.

Part 7: The Future – What “Exclusive” Means for Pirate Warriors 4

As of late 2025, One Piece Pirate Warriors 4 has received its final content update. However, the term “exclusive” continues to evolve:

  • Switch Exclusive Feature: The handheld version has an exclusive “Local Co-op” mode using two Joy-Cons, which is not available on PlayStation or PC without third-party tools.
  • Shueisha Exclusive Skins: In Japan, certain manga-color alternate costumes (like “Onigashima Battle Worn”) were exclusive to the Shonen Jump eShop. These are the rarest DLCs to find in NSP format.
  • Emulator Exclusives: PC emulators allow “mod exclusives” – for example, a mod that replaces Roger’s cutscene model with a fully playable Gol D. Roger, something never officially released.
