Sophisticated Backpacks is a great mod, but even if you tweak the inventory slot count in its config file, it caps at 144 — which might not be enough for some players. Inspired by The Fool modpack, this addon uses Mixin to significantly raise the config limits for both inventory slots and upgrade slots. Now, you can have an ultra-large backpack!

First, you need to launch the game once to activate this mod. After that, you'll notice that the inventory slot limit in sophisticatedbackpacks-server.toml is no longer capped at 144. Also, changes to the backpack's inventory slot count will only apply to newly obtained backpacks.

Warning: Do not stuff too many items into an ultra-large backpack — this may lead to severe lag, crashes, or potential world corruption. Use with caution!
