Is it safe to use the Gateway 2.0b2 files to create an EmuNand on a 4.5 3DS with either a Supercard DStwo or a R4i RTS 3DS (www.r4ids.cn)? My two systems have never been used except to update to 4.5 via cartridge. I don't want to play any roms, I just need to get a stable EmuNand, update to 7.1, and download the Zelda Four Swords DSiware game and the Bravely Default demo. I don't even plan on playing the downloaded games for a while (until at least the version 2.0 of the Gateway software is released). I'm just going to back everything up and then put everything away for at least a few months.
