Renamed ROM to 3dz?
There is a few threads already about smash bros. online not working. From memory it's nothing to do with the ROM region (if you are having the same problem, that is)
Hey, I am from Aus too and am trying to sort out the same thing. The update is in the e-shop under recent arrivals, just go there and download that and your game should be 1.02 version. As for the error when going online, I have received the same message, but I think it is from having header information that is not quite right for the region, so I will be trying a few different headers today, someone else may have to confirm that is the error message you get with the wrong header.
Yeah.
I'll have a look
I'll try a few different headers now and let you know if I find one that works.
Got mine to work using the gateway to dump another one of my legit games and then put that header in, so definitely that error is from a header which won't work. The header that worked for me in the end was 45F80090.
Alright, got it working, but the lag is insane. Oh well
