Texture Packs not loading all the way

[phly95]

I'm using Hypatia's Wind Waker mod and I'm not getting all the greatness I've seen in the screenshots.

here are the results I get

As you can see, some UI elements load fine, but the water and the sail are pixelated, even though I see it clearly on the screenshots.
Is this a glitch in my dolphin or a problem with the texture packs. Hypatia did note that Dolphin had issues with the textures on the start screen which I hope gets fixed, but I'm having problems with the stuff that is supposed to show.

Make sure you're using the same texture cache setting the creator was using – I'd assume they were using the default "fast" setting, but play around with it if necessary. (Also make sure you're using OpenGL, apparently D3D(11) has issues with replacement textures.)

...I tried this out myself (Dolphin 3.5-663, old shitty OpenGL) and I got the high-res sail texture, but some other textures were replaced with the wrong texture, e.g. the white highlights on the waves being replaced with blue rectangles (thus the sea looks entirely blue, but at a certain angle you just see those blue rectangles sticking out a bit). Seems that the issues may be different per-computer or per-settings or whatever. (oh god I'm too lazy to actually properly diagnose this kind of shit)
