OreCompress and PlateCompress are now merged into one. With it came a significant code rewrite which greatly simplified the process of adding new ores; generalizing the mod behavior. If you want to change mod settings, please do it before starting the game. I did test changing the settings of existing game and it worked as far as i could tell.

This mod lets you compress and decompress ores and plates. 20 items into 1 dense cube of resource. You need an assembler to compress and decompress. Some of them can be smelted or used as fuel.
Cheaty? Maybe a little in the sense that to transport ores around your base you need 20 times less robots. But it comes at a cost of more logistics complexion. By default the process of smelting with compressed recipes is lossy, but slightly faster. You will also get more fuel energy out of a single piece of coal. But use of this mod may increase your game performance in megabase scale.
