Hacking EmuNAND : thinks to do before ?

[alucard_xs]

Hi

I'm gonna install emunand on my SD card but I've got some questions before :

1) I was using my switch with Reinx before and I've got 4 backups (nsp installed) on my SD card, does the emunand installation erase my sdcard ?

2) is a NAND backup mandatory with SX OS ? I've got already a NAND backup (backuped before playing with NSPs with ReinX), maybe it 's enough (and better as it was brand new).

3) can I transfer the NINTENDO directory (with all my installed NSP from an old SDcard to a new one ?), will it still work after emunand installed ?

4) should I format my console before installing emunand (all my NSP are installed on my SD card, nothing on my sysNAND)


Thanks
