Offline mode for Minecraft 1.5.X - 1.6.X+ - MCOpenLauncher Updates Here

[Kaise123]

This post is reserved for updates to McOpenLauncher. As soon as I find out about a new version, I'll update this post.

As of now, The latest McOpenLauncher known is: 1.2.5
And the download links for this version:
Windows EXE (V1.2.5 for Minecraft 1.5.2-1.6.4+)
Universal JAR (V1.2.5 for Minecraft 1.5.2-1.6.4+)

Download the Windows EXE if you are running Windows, Otherwise use the Jar. Requires Java 6/1.6 or above, and should work on Windows XP, Vista (If your lucky), 7, 8.

The launcher will work for snapshot versions, and should be compatible with any future versions of Minecraft above the current 1.6.4.

McOpenLauncher is an offline mode/'cracked'* launcher for Minecraft versions 1.5 onwards, based on Mojang's new Minecraft launcher. I am not the creator of this launcher.

For anyone without a premium Minecraft account who wants to play the Minecraft 1.6 snapshots, Here is a patched 2013w16a launcher. You just enter a username and pick the snapshot you want to use.

You MUST extract all the files in the archive to run it, Just open 'MCOpenLauncher' to open it. Enjoy

Same version is still working with everything up to 13w22a tested.

If only Sparamoule cracked the launcher so that you could also play it on pure LAN (i.e. without an internet connection).
On start it contacts the server to retrieve a list with the current minecraft versions, but you're only able to choose a version when connected to the internet =/

Anywho: props to Sparamoule and Kaise123 for the share! =)

edit: You can play without internet if putting all the needed files together and running the jar using javaw incl. parameters

update: Unfortunately the latest snapshot 13w23a doesn't work with MCOpenLauncher 0.7, Mojang have updated theirs to 0.8.3 =(

Thanks! I'm excited for horse racing in the server when it's public and is ready for multiplayer!
