DarkRooms
Java mod listed for Minecraft 1.20–1.21. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
This mod brings back the old dark room mechanics that was primarily used to generate EMC, it does this by making it that when grass is bonemealed, if the light level is 0, it drops the grass / flowers instead of planting them.
