Help with supermario galaxy texture mod

[Barack91]

Hi guys, I'm having trouble lately using the supermario galaxy hd texture mod found in this site.
I have done all that I could understand to do like:
1 Using the latest ishikura
2 Put the folder in user/documents/dolphin emulator/load/texture/RMGE01
3 checked the use custom textures etc

what else should I do?
I'm using textures efb copies with cache enabled and accuracy set to the fastest and I'm not particularly sure of that choice

Thanks to all in advance
