Persistent Redstone Logic Mod brings programmable Lua computers into your Minecraft world with full state persistence. Unlike traditional machines that reset when chunks unload, this mod keeps computer programs running across chunk reloads and server restarts. You can write custom scripts, build automated control setups, and connect devices through dedicated cables and peripheral blocks. It runs a lightweight environment that keeps memory usage low while processing scripts smoothly.
