Gotcha. Thanks for the leads.I only tested the card with the kernel the seller supplied which was extra bad. But I would imagine that games like pokemon black/white 2, the games that use nand saving and some other games like Smurfs 2/ Cars 2/ Tangled/ Toy Story 3 etc might cause issues.
Indeed, you raised some fair points. I've seen people pay for modding despite knowing of the guide. And the possibility of sharing a cart might be appealing, especially if getting multiple.Presonally I don't see 3DS modding as very accessible. There are too many steps involved for my taste. And ofc some people don't want to mod their system/ want to use the cards in a moment where modding is not an option (e.g. with friends in the holidays etc)
