Did not find a thread about this, but it looks seriously great: Link to the showcase
I'm not up to date with OoT ROM hacking, but I'm amazed with how much the creators were able to change in this game for this. They went as far as allowing quick change of Tunics/Boots with the DPAD. The music is also sounding pretty good, and I like how they managed to capture OoT's music style so well (although some compositions seems to be based on other Zelda songs)
I also like how low key they have been with the project, making it less likely for Nintendo to shut it down. Though I'm not helping them much by sharing it here.
