I am going to experiment with this later.
I have a O3DS on 9.5.0-22, so I can use the browser exploit to install OoT3DHax.
I also have a Powersaves dongle. They use to be easy to get at Gamestop or Target. I got mine when it first hit the stores.
Anyways, I will be backing up my O3DS 10.1.0-27 OoT3DHax save and seeing if this method indeed does work when restoring a OoT3DHax save.
If so, I will share it with y'all who have Powersaves.
Mind sharing that O3DS 10.1.0-27 OoT3DHax save? I'm assuming you own a US cart and I'd like to try this method myself on my O3DS of the same firmware. If it works, I'll try to make Powersaves files with hax applied to other firmwares the hax is capable of exploiting.
Can somebody confirm is this works? looks like i found a gold mine in this p?ost thank you but yeah, i guess this is the only method i have since i can't acccess to the launcher.
Also i wanted to ask, wich file did you download? the one from the link avove or this "Second-degree Hax installer for 3DS"? thanks again i guess i'll try this method! i'm 9.9-26u do you think it'll work?
EDIT-
Well nvm is it necessary to have that Powersave thing? ugh looks like i'll never gonna use homebrew again ;____;
You'd need some sort of way to apply save backups onto the cart and most people use Powersaves for that. I don't know if it'll work out the same for other generic 3DS cart save dongle but I wish you the best of luck with that.
