About this project
What does Beta Days add?

Do you want to take a trip down memory lane? This mod is for you if you would like to emulate Minecraft Beta functionality and features inside of modern Minecraft.
For even more nostalgia, we recommend pairing this with any resource pack (try our Minecraft Beta resource pack - Legacy Default) that adds old textures and sounds, and this mod with Beta+ by therealMRBURGERUS, which is a replica of the old Beta and Alpha generator. You could use old seeds with it like Glacier and worstseedever.
🛠️ Features
Old Hud
Gives the classic HUD, removing the hunger bar, and adjusting the position of the armor bar. Enabling this is only the aesthetic of the HUD. You may want to disable hunger, which will make food give you health when eaten.

Enable Beta Main Menu
This will replace your main menu with the one from beta with minor tweaks. The version number is at the top left, and the background is the classic tiling dirt background.

Classic Beta Style Bow
Allows you to shoot the bow without having to recharge, just like in beta.

Disable Nether Fog
Disables the Nether fog and allows you to see more clearly and far in the Nether.

Disable 1.9+ Combat System
Spam click with your weapons to your heart's content. The classic system is back. I can hear your mice now!
Disable Sprinting
Useful if you want to capture the beta experience. This also disables the new swimming in 1.14.4+.
Disable Hunger
Useful if you want to capture the beta experience. This will make food give you health points instead of hunger points and will be eaten instantly.
Disable Experience Drops
Useful if you want to capture the beta experience. Killing mobs will stop them from dropping XP.
Custom Dimension Messages
Will display classic messages on the loading screen like “Entering the Nether” and “Entering the End,” just how beta did it back in the day.
… And More!
