Backpack Plus: Sophisticated Backpacks Addon

Sophisticated Backpacks mod offers an excellent backpack system, but even when adjusting settings, the maximum slot count is limited to 144 — which might not be enough for some players. This addon, inspired by The Fool modpack, uses Mixin technology to dramatically increase limits for both storage slots and upgrade slots. Now you can create a truly massive backpack!

To get started, you need to launch the game once with the mod installed. After that, you'll find that the slot limit in the sophisticatedbackpacks-server.toml file no longer applies. It's important to note that changes to slot count only apply to new backpacks you obtain after installing the mod.

Warning: It's not recommended to fill an ultra-large backpack with excessive amounts of items — this can cause significant lag, lead to game crashes, or even world corruption. Use with caution!
