Condensed Blocks is a modification to Minecraft that adds extra blocks created with 9 x 9 stacks of items, enabling users to store more items in the same inventory space. Includes support by default for IndustrialCraft 2, Modular Force Field System, BuildCraft, Forestry and Railcraft.

Condensed Blocks currently uses the individual mod config files to gain the IDs to use, rather than refer to the item in full. As such, those with ID Resolver need to change all IDs used by the mods to their original defaults.
