How to use this website to play Minecraft

NOTE: This is a rough, incomplete, draft of the guide until such a time when I can provide a complete reference.


  1. Sign up for a Retrocraft.net account
    1. The username of this account must be the username you use in-game
    2. The username does not have to be your official Mojang/Minecraft username however...
      1. ... if it is not your official username, you must use offline mode to set your usename (more on that later)
      2. ... if you change you Mojang/Minecraft username, you will need to use offline mode too as retrocraft usernames can't be changed!
  2. Download MultiMC client

Minecraft Alpha/Beta

  1. Open MultiMC and create an instance for the version you wish to play (refer to MultiMC guides for more help on this)
  2. Edit the instance and go to "Settings"
  3. Tick "Java/JVM Arguments" and paste the following code in there:
    -Dhttp.proxyHost=retrocraft.net -Dhttp.proxyPort=80
  4. Launch and play!
