Hmm... I don't know how possible this is. But how your machine is setup, would it be possible to have an ModMii kind of way to fetch needed tools etc. for downgrading, updating things? It would be perfect to sync with
https://3ds.guide/ for anyone who are totally new. I know this isn't something you should go for now. It's just a general question.
ModMii for those who don't know. It's a program made for the Wii that you used on your computer. It downloaded all you needed, made a guide etc. so you just followed.
