Oh I didn't realize I could just yours, nor where it is. And I did take screenshots but this site won't let me upload file or share links.
This is my absolute first time messing with this stuff, I followed the 3ds.guide and successfully have my 3ds ready and I have my SOSTOT game cartridge, so all that's left is figuring out how to install this hack :0 I apologize for the inconvenience
EDIT: okay I re-read and I think I understand! oops hehe, going to try "that iso site", thank you for your patience and hard work!
