what do you mean by use them? install them? on which nand
download the FIRMS.7z from the AuReiNAND github page and grab Firmware90.bin from the A9LH folder in the 7z then put that in the Aurei folder with where firmware.bin is at.
set SysNAND to boot (check updated sysnand mode and use 9.0 Firm as default use in AuReiNAND via holding select on bootup). (the 3ds will now boot to SysNAND 9.2 by default to work with Gateway)
after you do this, place LAUNCHER.DAT on the root of your SD Card from "GW-ULTRA-3-7-1-BETA.zip" on the Gateway website.
the lase step is to follow the steps in this zip https://gbatemp.net/attachments/gateway-cia-v1-1-7z.42248/
---------------------
afterward, launching Gateway is as easy as putting the cart in, turning on the 3DS power, then launching the Gateway CIA from the home menu.
The Gateway Launcher should take over and boot into EmuNAND.
