Is it possible to backup my 3ds friend codes list and friend code and restore it onto another system?
Yes, you can either use Decrypt9's option to dump friendsave.bin then restore it to another 3DS using the inject option or you can use GodMode9 to copy 1:/data/$[SYSID0]/sysdata/00010032/00000000 from one console to another. You may beed to fix the CMAC after (which is done by press A on the 00000000 file and choosing Calculate CMAC if the option is there).Is it possible to backup my 3ds friend codes list and friend code and restore it onto another system?
