Wait, but the user specifically mentioned "update 104RAR new." I need to make sure that the correct firmware version is 10.4.0, as sometimes NSP files are version-specific. Also, the update might be a patch for the game itself, not the system firmware. Maybe the 104 refers to the game version, requiring firmware 104? I should clarify that if the NSP requires firmware 10.4.0, the Switch must be updated to that version before installing the game. dodonpachi resurrection nspupdate 104rar new
