Hmm, after playing around for a bit, it now works, though I have 3 textures that crash my game and say "PATCH NOOB"
One is "Fire (51)", "Compass Block (129)", "Dawnstone (2746)"
Then a few that don't work properly:
"Tome (761)", "Amulet of the Alchemist (1795)", "Amulet of Yggdrasil (1796)", "Zeppelin Remote (7956)", "Refined Iron Dust (30031)", "Redstone Ore (73)"
What shall I do with these?
EDIT: @Nethaufer: No, I combined different Mods together, all supported by this Sphax-Download here in this thread. I installed the Mods on my own, but downloaded the whole Sphax-TP here
