Sophisticated Storage Plus
Java mod listed for Minecraft 1.20–1.21. Downloads from the MC Java Mods app on Android.
Allow Sophisticated Storage's Barrel/Chest/Shulker Box to exceed the default limits of 180 inventory slots and 10 upgrade slots via config, which means…
I don't know my version or loader
Sophisticated Storage is a great mod, but even if you tweak the inventory slot count in its config file, it caps at 180 — which might not be enough for some players.
This addon uses Mixin to significantly raise the config limits for both inventory slots and upgrade slots. Now, you can have an ultra-large barrel/chest/shulker box!
First, you need to launch the game once to activate this mod.
After that, you'll notice that the inventory slot limit in sophisticatedstorage-server.toml is no longer capped at 180.
Warning: Do not stuff too many items into an ultra-large container — this may lead to severe lag, crashes, or potential world corruption. Use with caution!
