Mash-Up Addon for Legacy4J
The Mash-Up Addon is an addon to the Legacy4J mod which implements all of the Mash-Up worlds into the mod.
Notice
This includes JUST the worlds! Not any of the texture packs! You may check out Festive Mash-Up or the Halloween Mash-Up by BrandonItaly, or the Fallout Mash-Up by RedRain0o0 for some of the textures.
FAQ
- Will you be adding the resource packs from the mash-ups to the world files?
Maybe in the future, but not now. The file size would be >500mb and I would rather have that job be for people with more experience than me.
