From what I've heard, it should be possible to port Ninjhax/RegionFOUR from OOT. If nobody here wants to take on the challenge, I could try.
Edit: Would this be something people want? No promises, but I'll attempt.
RegionFOUR already works with OOT, but you have to compile it yourself and only works with n3ds... I complied one and never worked on my o3ds....well it kinnda loads but loads so fast and returned to the home menu in a flash
I would love to see a port of ninjahax for OTT and rejionfour for o3ds
