not really just put the launcher.dat onto the root of your microsd card and load it with either cubic ninja or zelda oot.Is there a tutorial out there?
Follow the tutorial I linked down to the T.I did that and loaded up zelda but gateway didn't come up?
Or he can downgrade to 4.2 (not sure if new3ds can) and use pasta with savedatafiler to install the save needed.Keep in mind, you need an old 3ds or 2ds that can already use gateway in order to inject the gateway save file into your copy of OOT, that or a 3ds save dongle like it states in the manual.
*Kinda useless info since you likely don't have it* With Cubic Ninja, you just download the save directly to the game via QR scan & internet connection.
Its cheaper to buy an R4i save dongle.I don't have another 3ds that can support gateway, looks like I need to find a cubic ninja game..
There are people here who will install mset on a N3DS if you send it to them, if you don't have your own CN or OOT/save dongle.
