after I got hiya installed I could copy it back in settings from sd to system.
auto
also when I installed with the guide it told me to open unlaunch through the homebrew launcher but that just froze it. So I renamed unlaunch boot.nds and it worked until I got to loading fat.
I wanted to see the height limit so I pillared up and after a long long time it crashed but it was a very good time until it did. when it crashed it didn't save to be expected.
