I have a 4.5 3DS XL with GW. SYSNand is backed up on my PC but I didn't set up EMUNAND yet. - a 4GB SD card is enough to install .cia-s with small content(no full games)? - When I go emunand will my sysnand saves be useless or it can be copied to the SD card? - If i want to update the GW launcher the process is old EMUNAND->old SYSNAND -> new SYSNAND -> new EMUNAND?
