on a modded Nintendo Switch and your DLCs or the IT Expansion update aren't showing up (or you're getting errors when installing the NSPs), here is a quick guide to getting everything working. Why this happens:

Update (released July 2022) added a staggering number of new parts, including:

Installing just this file leaves you with a bare-bones game prone to launch bugs. 2. The Update File (v1.x.x)

PC Building Simulator features DLC packs that add new content, such as custom parts, cases, and game modes. The DLC packs are available for purchase on the Nintendo eShop and can be downloaded and installed through the console's built-in software update system.

Drag and drop your PC Building Simulator base game NSP, the latest update file, and the DLC NSPs into the folder simultaneously.

If you have already installed the game and are facing black screens or instant crashes, use these proven fixes.

: Scan your files for integrity errors to ensure the download wasn't corrupted during transfer. If you want to optimize your setup further, let me know: Which custom firmware (Atmosphère, SX OS, etc.) you use. The specific error code or message you see. Your current firmware version .

They act as digital "keys" unlocking content already hidden inside the update files.

By following these steps, you should be able to resolve the DLC and update issues in PC Building Simulator on Nintendo Switch.

Ensure your Custom Firmware (CFW) like Atmosphere has the latest signature patches. Without these, the Switch cannot verify the "fake" tickets associated with NSP DLCs.

Always ensure your Update file is installed after the base NSP but before you attempt to launch the DLC content. 2. The "Signature" and "Amiibo" Error Fix

Check your game title on the Switch home screen by pressing the + button. Check the version number. If it says 1.0.0 , your update failed to install. Re-install the latest update NSP. The DLC keys will automatically activate once the game updates.

: Obtain NSC Builder or Switch Army Knife (SAK).

: Use the built-in Switch utility to ensure files weren't damaged during transfer. Go to System Settings > Data Management > Manage Software , select the game, and choose [Check for Corrupt Data] Update System Firmware
