Hacking Emulation Should I install forwarders on syscfw?

[meng_]

basically what the title says, for context i bought a switch premodded and i do not plan on connecting it to the internet, however the previous guy that modded it did not include emummc, so i'm asking if i should install or should i not.
also is there a way to backup the nand without too much hassle? i sadly do not have 30-ish gb to spare

Need about 30GB of space if you want to backup NAND.
