Pylon

Pylon allows legacy Minecraft versions to run with LWJGL 3. It replaces the outdated windowing system with SDL 3, and serves as a library for mods.

Installation

IMPORTANT:

On versions older than 1.6 a deAWT mod is required. LegacyFix is recommended.

Forge

Depending on the game version:

  • 1.3 or older: Follow Other.
  • 1.4: Put the mod jar into the .minecraft/coremods folder.
  • 1.5 or newer: Put the mod jar into the .minecraft/mods folder.

Fabric

Put the mod jar into the .minecraft/mods folder.

Other

If you are playing on Vanilla or using an older mod loader (like Risugami's), you need to install Pylon as a Java Agent.

Pylon can also be put in place of LWJGL2 directly, but game patches won't be available.
