Hello ! First, I'm sorry I know M3 adapter are no longer supported but It figured the M3i Zero work on O3DS, but I've seen eveyrone saying it don't. Could someone explain to me why does it work on my 3DS ? thanks

Is your 3DS hacked and running a CFW?

That's the reason why it works. Luma3DS removes the TWL signature checks and allows flashcarts that previously ran on the 3DS to work again.Huh, yes Luma3DS this could be the reason why it works right ?

It's cool, I personally always suggest asking questions over sitting them.Ok, I understand now sorry for this thread and thanks for your help !
