I wonder why. why you have to be to force 6.2? at the end if you connect a 3ds firmware type the 5.0x with those MAC Address .. must meet other mii the same .. No? why should not meet them? is simply connected via a router / accesspoint (via PC) to specific network .. you might as well do it with other fimware .. and my question is summary: okay firmware 5.0x? - 5.1? thanks ..
