Porting =/= Remaking
I admit it's quite confusing, especially when there are a mix of then, like Zelda OOT 3D, Starfox 64 etc
Porting means getting the original source code of the game and changng it to adapt the new device's needs.
Remaking means make the game from ground-zero, so you won't use the original source code, probably there will be new textures, new 3D models, and maybe enchacements.
Zelda OOT 3D uses the original source-code, but almost every face has been remodeled, there are many retextures, so it's kind a mix.
One could say it's a remake, other could say it's an enchanced port, but I think it doesn't make much difference.
