Overview

This mod restores and fixes the hidden multiplayer functionality for Minecraft Alpha versions 1.0.5 through 1.0.14. During this era of development, multiplayer was often disabled or locked behind "invite codes." This patch re-enables the Multiplayer button and allows you to connect to any server using a standard IP address.

Features

  • Multiplayer Unlocked: Re-enables the Multiplayer button on the main menu.
  • Invite Bypass: Removes the requirement for a secret invite code; simply type your IP and connect.
  • IP Saving: Your last entered server address is now saved to your options file for easier access.
