Where it goes
Is StackUpUp required on the client, server, or both?
The project page does not say whether this file belongs on the client, dedicated server, or both.

Install Forgelin-Continuous, MixinBooter first. We found matching files for this game-version and loader setup.

About this project
What does StackUpUp add?
StackUpUp is a Minecraft 1.12.2 mod that raises item stack limits beyond 64 with a new rule-based system.
It is derived from StackUp, but focuses on a cleaner 1.12.2-only rewrite with better support for metadata-based items such as GregTech CEu materials, OreDictionary matching, and modern MixinBooter-based compatibility patches.
Main features:
- Raise stack sizes beyond vanilla limits
- Match rules by item, mod, ore dictionary, metadata, and size
- Better support for same-ID different-meta items
- Cleaner large stack count display and tooltip info
- Built for Minecraft 1.12.2 only
