I had the Tegra keys and title keys issue with the latest version (v1.2), and no matter what I did it just wouldn't work. But after trying with the v1.1 it worked just fine
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
