Pokémon: Let’s Go, Pikachu! for Nintendo Switch: How to Get the NSP, XCI, and Updates Working
Released as a vibrant reimagining of the classic Pokémon Yellow, Pokémon: Let’s Go, Pikachu! brought the Kanto region to the Nintendo Switch with HD graphics and integrated Pokémon GO mechanics. For enthusiasts in the emulation and modding community, getting the game running smoothly requires understanding the specific file formats like NSP and XCI, as well as how to apply necessary updates (UPD).
In this guide, we’ll break down everything you need to know to get Pokémon: Let’s Go, Pikachu! working on your hardware or emulator. Understanding the Formats: NSP vs. XCI
When looking for Switch game files, you’ll encounter two primary formats:
XCI (NX Card Image): This is a raw dump of the physical game cartridge. It’s often preferred by users of the SX OS or those who want a "plug-and-play" experience that mimics inserting a physical cart.
NSP (Nintendo Submission Package): This is the format used for digital eShop titles. NSPs are generally easier to install directly onto the Switch’s internal storage or SD card using installers like Tinfoil or Goldleaf.
Which should you choose? For Pokémon: Let’s Go, Pikachu!, both work perfectly. However, if you are using an emulator like Yuzu or Ryujinx, NSPs are often slightly more convenient for managing updates and DLC. How to Install Updates (UPD)
To ensure the game is "working" without crashes or bugs, you must apply the latest updates. Game updates are almost always distributed as NSP files, regardless of whether your base game is XCI or NSP.
On Hardware: Use an installer (like Tinfoil) to "push" the update NSP onto your console.
On Emulator: In Yuzu or Ryujinx, go to File > Install Files to NAND and select your Update NSP. This will patch your version (e.g., from v1.0.0 to v1.0.2). Step-by-Step: Getting the Game to Work
If you are struggling to get the game to boot, follow this checklist: 1. Verify Your Keys (Prod.keys)
Switch games are encrypted. Whether you are using a modded console or an emulator, you need the latest prod.keys file dumped from a Switch. If your keys are outdated, Pokémon: Let’s Go, Pikachu! may show a black screen or fail to launch. 2. Clear Shader Cache (For Emulator Users)
If the game hangs during the opening cinematic of Pikachu, it’s likely a shader compilation issue. Try clearing your shader cache or enabling "Vulkan" as the graphics API in your settings for better stability. 3. Controller Configuration
Unlike traditional Pokémon games, Let’s Go was designed for single Joy-Con play or the Poké Ball Plus. Handheld Mode: Works like a standard game.
Docked Mode: You must emulate a "Pro Controller" or "Dual Joy-Cons" in your settings. Note that the game does not support the Pro Controller officially, so emulators often have to "trick" the game into thinking a Joy-Con is being used. Common Fixes for "Not Working" Issues
Infinite Loading Screen: This is usually caused by a missing update or corrupted firmware files. Ensure you have the latest System Firmware (HOS) files installed in your emulator's system folder. pokemon lets go pikachu switch nsp xci upd work
Low FPS: Let’s Go, Pikachu! is surprisingly demanding in forested areas like Viridian Forest. Ensure "Undocked Mode" is selected in your emulator to lower the resolution and boost performance.
Softlocks during Catching: If your motion controls aren't configured, you might get stuck in the catching screen. Map your "Shake" or "Gyro" controls to a button to ensure you can throw Poké Balls properly. Conclusion
Getting Pokémon: Let’s Go, Pikachu! working via NSP or XCI is a straightforward process once you have the right updates and keys. Whether you're revisiting Kanto for the nostalgia or trying to complete your Pokédex by transferring Mons from your phone, following the steps above ensures a smooth, crash-free experience.
Pro Tip: Always keep your UPD files separate from your base game files to make troubleshooting easier if a patch ever becomes corrupted!

As of 2026, Pokémon: Let's Go, Pikachu! is considered one of the most stable titles for both hardware and emulation.
On Modified Hardware: Both XCI and NSP formats work flawlessly on Switch consoles running Atmosphere or similar CFW. On Emulators:
Graphics: The game runs at a stable 30 FPS or 60 FPS (with mods).
Controls: Since the original game relies heavily on motion controls (the "flick" to catch Pokémon), emulators require you to map these to a mouse or a controller's gyro sensor.
Connectivity: Linking to Pokémon GO or using the "Poké Ball Plus" accessory typically requires specific hardware passthrough or Bluetooth configurations that can be finicky. Summary of the Workflow
To get the game "working" in a modern setup, the standard path is:
Obtain the Base Game: Usually a large (~4GB) XCI or NSP file. Obtain the Update: A smaller NSP file (v1.0.2). Install/Load:
Console: Install both via a title manager (like Tinfoil or DBI).
Emulator: Add the base game to your library and right-click to "Install to NAND" or "Manage Title Updates" to apply the UPD file.
Note: Downloading these files from unofficial sources constitutes digital piracy. It is always recommended to use your own legally purchased software by dumping the files from your own console.
