In this video I will attempt to downgrade a Minecraft Java world through all the versions. Starting from the latest version and going all the way back to the First infinite world version inf2010227. During this experiment we will encounter chunk corruption, deleted blocks, chunk deletion, world regeneration, and storage version changes, showing how Minecraft's world format has changed over time and how compatible different versions are with each other.
