Phosphor Legacy Forge

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Forge only.

Minecraft 1.9.4–1.11.2Newest
Minecraft 1.8.8–1.8.9

⬇ Download for 1.9.4–1.11.2 ⬇ Download for 1.8.8–1.8.9

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.

Phosphor Legacy Forge

This is a port of JellySquid's Phosphor mod to Forge 1.8.9 and 1.9.4-1.11.2 .

Mod Compatibility

Tested with OptiFine, Dynamic Lights, LiteLoader, Essential, Patcher and other coremods.

This mod has included mixin 0.7.11; Should works fine with other mixin 0.7 mods.

If it crashes with LiteLoader, make sure LiteLoader was in mods folder and loads AFTER mixin 0.7/0.8 mods. DO NOT install LiteLoader with Forge as a lib !

Not compatible with Legacy SpongeForge. Due to SpongeForge causes weird invalid mixins crashes and uses extremely outdated mixin versions.
