Resin Bundle Pins
Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Resin Bundle Pins
A simple add-on to Bundle Pins that adds support for resin pins to 1.21.1 with resin from Vanilla Backport.
The following extra files are also available:
- assets : resourcepack for the client to display the pin
- data : datapack for the server to register & craft the pin
- merged : resourcepack & datapack (assets & data) unified in one file, can be used interchangeably by client & server, but still needs to be on both!
