It's normal if you see 80% of the levels not scaled.
It doesn't cover everything (the game dumps dozens and dozens of tiles of different colors every once in a while, so I would have to play the entire game while dumping to be sure I got everything). Environments, characters and a few remaining weapon icons upscaled with xBRZ x5 as an experiment. Many HUD and menu elements from the Wind Waker texture pack, as well as some effects. Some textures made by me (using high resolution artworks as the source).
Luckily, it shares a bunch of textures with Zelda Wind Waker, so I could make use of them for this pack.
While I was doing aspect ratio mods for this game and others, I suddenly wanted to make a texture pack for this game.
