I don't know my version or loader
Ever wanted to enjoy a classic 1996 platformer in a completely new way? Now you can!
Retro64 lets you play as your favorite plumber within your Minecraft world. Run, jump, and ground-pound enemies, exactly how it is in the real game!
This uses the SM64 decomp project to give you an 1:1 simulation of the original game's physics.

FAQ
Does this mod work with shaders (optifine)?
No, shaders are currently not supported. Additionally, any mod that modifies Minecraft's rendering is not supported. Examples of such mods are OptiFine, Sodium, ImmediatelyFast, etc.
Is this mod compatible with this [other mod]?
I doubt it, but I'll try to add compatibility with other mods in the future, although it's not a priority at the moment.
Is there Multiplayer support?
Yes, but it's very work in progress. If you want the best experience, I suggest playing in singleplayer for now!
