1. exFAT (its a 128GB card)
2. "Removable Disk (G)"
3. Yes. And I just recopied them over as well
4. No. I seen the option last night, but have not tried it. Now, I can't even get to the menu
5. Nothing. I put the jig in and place the Switch into RCM, connect it to Windows, launch payload via TegraRCMSmash, then a black CMD screen appears/disappears. Switch screen stays black.
I've never had this much trouble before updating to 5.1.0
6. No. But i will then report back
