The number "220 Install" is a bit confusing. It could refer to a version number, like v2.2.0. But I don't find any official information about such a mod. Alternatively, "220 Install" might be a mistranslation or a mix of words. Maybe it's "Install 2.20" referring to a specific version of a mod.
But "Purapura" could be a translation issue. In Japanese, "Pura Pura" (ぷらぷら) means something like floating or drifting. Maybe that's referring to a specific mod focused on navigation or exploring the game world. Alternatively, it might be a fan-created patch or mod by a user named "Purapura."
The user might be looking for instructions on how to install a spatial audio mod or a navigation enhancement. I should explain that installing such mods typically requires technical skills and some understanding of Switch hacking. Also, mention the risks involved with modding hardware and software, especially piracy concerns.
