pretty sure this is exactly the same as the gateway im going to assume your trying to set up emunand or "nand emulate" as mt calls it follow the instructions on par until you get to the part where you update your emunand/nand-emulate boot into the MT mode where it says MT3D 4.5.10 on the bottom right of the top screen if it says MT3D in that menu your good to setup your net...test it then go into the other settings..to be super safe make sure it has the MT3d 4.5.10 on the top screen again then go to other settings..scroll all the way to the right and update your system..DO NOT exit the settings menu after setting up your net as it will boot up into your real nand..stay in the settings menu while in emunand and follow with the update in the settings menu this seems to be the correct way to do it and ive done it on both a 3ds and a 3ds xl with a gateway (mt is a clone only with multirom support) so its the same thing (sorry if my explanations are a bit odd been a long day
