I know that is impossible t find this kind of key.. is harder than find the key to that .rar from the infame youtube video..
is was just wondering if it was a single shot to all systems or is a mission impossible..
can't you emulate a fake eshop using dns or router firewall rules?
IF the 3ds get generic data from the eshop and later encript it..
it can download anything from a fake eshop..
