nope, there is no legit OOT cia dumps as it was never included as a pre-installed bundle....damn you 25th anniversary console coming with the cart
Isn't OoT 3D sold on the eShop, though? I imagine if you had an emuNAND set up you could buy it there, make a legit CIA via FunkyCIA and then install it to your sysNAND. The problem then becomes does the exploit even work with the eShop version? If it does, I imagine it'll be pulled and fixed pretty quickly..
