Hi there,
I'm running Minecraft 1.4.6 and using Minecraft Forge 489 + OptiFine Ultra A2. I downloaded Shaders Mod from here: http://files.minecraft-modding.de/index.php?a=download&q=96 and paste the files into minecraft.jar. If I don't use Magic Launcher / any mods and only put the Shedar mod in it it works, but if I add MC Forge it says incompatible (Magic Launcher says that)
