ok, thats a bunch of questions… there is already space on the sdcard for patches - yes you can use wifi to transfer - see the organelle manual
yes, the sdcard can be ‘expanded’ to 64gb, using disk/gparted.
i think this is covered in this thread at the end… its a bit technical, but i think info is there…
(unfortunately, at the moment there is not really an easier way)
id try to avoid usb, its much easier to use wifi/sdcard
start the WIFI in AP (access point) mode, then you can connect directly to it.
from there the browser gives you the option to create a wifi network.
should be in the manual iirc.
depends a little on which patch, but for most patches (excluding orac), simply select ‘save new’ from menu (under storage)
you can later rename this patch in using the file manager browser
sorry this is a bit terse, but lots of questions… if you need more details on some feel free to ask for details where needed.
