About this project
What does Legacy4J add?

Legacy4J is a mod about nostalgia of old 4J Studios Minecraft Legacy Edition. The main objective of this mod is remake every aspect of Legacy Console Edition in 1:1 for Java Edition versions, adding its exclusive features, and bringing it to modern versions.
This includes an accurate controller support, the control tooltips, the crafting menu, the creative flight, the gamma shader, the scaling, the HUD, and more!

Not only that, but several QOL features have been added in addition to those already present in the Legacy Edition, such as Resource Albums, Global Packs, World Templates, an integrated Mods screen, options related to terrain fog and more. You can see more about this on the project wiki!
