From the moment I started playing OoT 3D, I knew right away that is was just the same exact game with updated visuals. It's a very sloppy port in that sense(as in, they couldn't hide that fact). Then there's all of the glitches from the original game, like you said, from the original. If it was an entirely new game, they would not be there. So, I do not see why it WOULDN'T be possible to mod for the game, and something makes me doubt they changed anything with the dlists. Honestly, when the time comes we have great 3DS emulation, and OoT 3D is discovered to be modifiable(no doubt by you or anyone else here on the GCN), I expect some awesome stuff from you. Like, really awesome stuff, that you can only do when you're Zeth. :3
