1. Download GERUDOKU.zip
2. Download the latest version of Xau's HD texture fix patcher
3. Run mcpatcher-1.1.9_04.exe (make sure the Minecraft client isn't running)
4. Click "Browse" next to "Texture Pack" and double-click GERUDOKU.zip
5. Under "Options", check everything (if you don't want johnsmith's custom lava and want to use the default, don't check "Custom Lava")
6. Click "Patch"
7. Close any of the windows you opened during this installation
8. Run the Minecraft client. The GERUDOKU texture pack should now be correctly installed with working animated water/lava/fire and no graphical glitches.
NOTE: If you're still getting a blackscreen on load after following these instructions, you may have to delete the "bin" folder in the /.minecraft/ directory and run the minecraft client again to redownload a fresh copy. After that you should be able to patch everything successfully and load the game without blackscreening.
If THAT doesn't work, try placing GERUDOKU.zip in the /.minecraft/texturepacks/ folder and loading it through minecraft's texture switcher. Then exit minecraft and follow the instructions above (steps 1-<object class="emojione" data="
