So I downloaded mcpatcher so I could use Gerudoku. I checked all boxes, chose the "Gerudoku" texture and put it 16x16, when I tested Minecraft, and all the default textures were replaced with the Gerudoku textures,I read about the patcher in the forum and it said this would only happen if I had it on any other texture pack the last time I was on, and I had it on default.
