All Of The Zelda Wind Waker HD Features Are Now Backported To the Gamecube Recompile
Still WIP, but there's been some huge performance increases and other updates too since last week. There's now the option if you have an HD Wii U disk to use all of the HD textures from it, the ambient occlusion, lighting, shadows, etc. https://github.com/elliotttate/Wind-Waker-Recomp
