First of all, it’s incredibly easy to mod it, and it’s something that, since the shop shut down, is necessary to have new experiences on it. Here’s a link to the site I used to mod my new Nintendo 2ds.
I just donated mine and there doesn’t seem to be one. Try to go to a computer store, SD card adapters aren’t very expensive these days.
P.S. I just remembered it uploads automatically if you’re connected to the internet
It needs to be doable through the device’s settings.
Eg. An android phone has the option to rename how it appears to other devices, while a speaker can’t do that
That’s Microsoft for you
