Fix: Ensure you are selecting the Base Game NSP. If you use a tool like Steam ROM Manager, check that it hasn't accidentally targeted the update file instead of the main game.

• Ryujinx: Go to File > Open Applet and try to install the NSP again. Check the console log (View > Console). Look for lines containing Program NCA. If the emulator says "Missing ticket" or "Missing key," this error can be a false flag. Ensure your prod.keys and title.keys are up to date.
• Legacy Yuzu: Use the "Install Files to NAND" option. If you get the error, right-click on the game in the game list (if listed) and select "Remove." Then install the base game NSP only, followed by updates.

Fix: Ensure your prod.keys are up to date and placed in the correct directory (e.g., the bin folder for SAC or the keys folder for Yuzu/Ryujinx).
