So you don't think Nintendo will make a distinction between a shared cert that has been shared over popular piracy sites/torrents which have been downloaded/used 1000's of times vs someone buying and dumping a cart cert that may get used a few times?
Nintendo are not going to kill off used switch sales by banning tons of used carts because that would be a disaster for a number of game chains and cause endless issues...
Edit: Ok so according to this youtube vid
https://www.youtube.com/watch?time_continue=293&v=waJxvBBAc84 they aren't banning anything but instead being able to detect a cart isn't being loaded via the game slot which makes sense.
So the issue seems to be to trick the switch into thinking dumped carts loading off internal or microsd are coming from the game slot,not sure if that sounds possible?
