What is the pack you use? Does it use DDS BC7? Or is it PNG? I don't know if Ishiiruka supports DDS BC7 yet.
It should be sufficient to only use the first three characters to name your texture pack folders. For example SB4E01 could just be named SB4.
You should also use the latest development of Dolphin instead of 5.0. Download the latest development build and unpack it somewhere and you are ready to go. It has been a while since 5.0 and the newer development builds support newer features as well a ton of improvements.
