So I have decided to install SSBU on my switch before release date, WITHOUT getting banned by Nintendo. I was planning on (I am on latest firmware with burnt fuses) backing up my 100% clean nand, removing wifi connections (before backing up nand), install CFW with no autoRCM, install SSBU without every getting out of airplane mode (besides Bluetooth), play it, then when I'm done I would remove the game from my SD card, then restore my nand. If I follow this procedure, I should in theory be able to play early, and not get banned, albeit losing my progress after I restore my nand.
