I was doubtful of this before any actual videos came out, but now I’m impressed by how they got past the cartridge protection system.
As for the reinsertion of the cartridge, as others have said, just don’t put 20 games on there and you’re fine.
I never understood people that liked having that many games at once… You definitely aren’t playing all of those.
I find the dumper is a weird accessory, as all it takes is one person with cfw and the nx tool to upload all the id’s and everyone else can use it. (of course, not for online, but if you don’t care about online, then it’s great)
Cry more, coward
