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.

📦 ResourcePack to Mod Library (RPtMLib)

RPtM is a lightweight Fabric utility that lets you bundle multiple resource packs directly into a single mod JAR. It uses the registerBuiltinResourcePack API to register assets as "Built-in" packs. You can use RPtM Converter to turn your resource packs to mods. All generated mods will be needing this library mod.

In Modrinth people tend to download mods over datapacks and resource packs. So i build that mod for people who suffer from that.

🛠️ Why use this?

Internal Loading: Packaged assets stay inside the JAR—no more messy folders.
Automatic Detection: If any RPtM mod is installed it will work without hustle.
Version Agnostic: Built to work on 1.20+.
Zero Bloat: No heavy dependencies or performance hits.
Mod Compatibility: Works with Respackopts natively.
Open Source: Both RPtMLib and RPtM Converter source code available on GitHub.
