the format of the recipes is this: slot1/slot2/slot3/slot4/slot5/slot6/slot7/slot8/slot9/result/ct/cn/ ct = custom texture cn = custom name items are separated with / because it's the supported format for the crafting system. this format makes it really easy to add recipes to the game with custom name and texture options, adding the opportunity to make mods for this Minecraft recreation. This does have support for blocks too, the renderer just does not support rendering them. anything can work basically.
