I followed the steps found on Gateway 3DS's site, but I can't get it to work. My N3DS has fw 9.0.0-20E. I used DevMenu.3ds found in the SDK-2.3.4-folder (SDK.DevKit.3DSWare.3DS.INTERNAL-BigBlueBox). Everytime I try Settings -> Profile -> Nintendo DS profile I am taking to where I can edit my profile, not to the Gateway 3DS menu or Gateway 3DS mode. I tried to do the install procedure again and DevMenu tells me that mset_eur.cia is already installed. Anyone else have this problem and/or is there a solution?
