you need headers to play online. Without it, you'll have no unique ID when going online.
You can't go online without a header, you need that unique ID so that you'll show up as something other than an invisible blank ghost.
Sky3DS users don't have a way to dump headers like Gateway users can. They have to rely on 9.0 3DS to use the Gateway exploit. You can borrow a friend's 3DS to use it for this if they're still on 9.2 or lower.
Gateway is the same, you need a header to play online and they have it quite easy to patch their games.
The headers can be of any one game. You can then use that one header for all your online games. The purpose is to not go online with the same header more than one at a time. So using your own header guarantees that only one of that header will go online. Just keep the game you use for it's header and never get rid of it or let anyone go online with it at the same time as you.
so i admit that i dont know much about the headers. Im coming from old school gba and stuff.Thats when i was around lol.
this 3ds and encrypted stuff is a tad weird to me. (i understood the playstation stuff tho)
So lets see if i understand this.
Each game cart is giving a different CardId?
So if i had 2 copies of SuperSmashBro they both would have different ids correct??? as in 1 could be 0001 and the other 0008
So if nintendo see that cardID 0001 is online on two different system at once, it would flag it in the system.
With no header it would show up and user XXX playing BLANK since there is no cardID. and the system would flag that due to it being and error.
So what we would want to do is copy the cardID from an old game and inject it to all the roms on your sky3ds.
So when you go online it will display that your online playing that old game and nintendo system will think everything is ok?
Someone please correct me where im wrong. i am trying to get and understanding of all this.
Also do these header effect save data? I would love to tranfer my original cart saves to the sky3 roms
