i have a old 3DS Xl on 9.2 and i followed the following steps(i didnt use the bluecard) 1) Copy the Gateway 3DS 3.2.0 ULTRA Launcher.dat to your New 3DS microSD card 2) Copy mset_<region>.cia to your New 3DS microSD card (where <region> is your console region) 3) Copy "DevMenu.3ds" to your Gateway 3DS microSD card. 4) Boot into the Gateway menu with your preferred entrypoint (Zelda or Cubic Ninja) 5) Select the new "NVRAM INSTALL" option from the menu, proceed with installation. 6) Once installed, boot into Gateway mode and launch DevMenu.3ds from the multirom menu (press SELECT) 7) Start DevMenu and import mset_<region>.cia from your SD card. 8) Reboot console and verify you can now boot into Gateway mode with the classic System Settings DS Profile method. (Settings -> Profile -> Nintendo DS profile) 9) Enjoy! No more cartridge swapping required to use Gateway 3DS on New 3DS! :-) i pretty sure i done all of them above but when i go into DS profile, nothing happen? is this feature for N3DS only? and old 3ds still have to use the browser exploit?
