Next, I should outline the steps to download and install the game. The user might be in a country where it's not available on the eShop, so they need an alternative. They would download the NSP file, extract it from RAR if necessary, and then transfer it to their Switch via a method like using Tinfoil with a firmware exploit or using tools like Goldleaf.

Another thing is that the RAR file might contain the NSP, which is the installable package. The user would need to extract the RAR to get the NSP file, then use a tool like Tinfoil to install it to the switch.

I need to mention the necessary tools: RAR Extractor, Tinfoil or Goldleaf for installation, and a USB cable. Also, the Switch must be on firmware 10.4.0 for the update 104RAR. Maybe the user is on an older firmware and needs to update their system, but that's a gray area. I should mention the risks of using homebrew and the importance of backing up personal data.

I should also mention that using these methods may brick the console if done incorrectly, so following trusted guides is crucial. Maybe recommend using a USB drive formatted as FAT32 for transferring files due to size limitations.

Also, check if there are any known issues with installing this specific game. Maybe community forums talk about issues with specific firmware versions. Including those could help troubleshoot potential problems.
