The Spawner GUI.zip file you have requested: Modifications / Risugamis Mods / v1701 / Minecraft Mod - Spawner GUI Beta 1.7_01 - 8.56kb is not available. Perhaps try browsing all files for the game Minecraft and upload any files you want to share or are missing. This is the only information we could locate:
Adds a GUI to all mob spawners, that will allow you to pick what mob to spawn. Mining spawners are reallowed. You can disable spawners with redstone as well. Should be compatible with all mobs, but don't expect the mobs with special spawn conditions to work everywhere. Animals require grass, Monsters require darkness, Slimes require being in their special chunks, and 0-16 depth. Requires ModLoader.
