I decided I should cross post this here from MinecraftForum.net

MCLauncher is a tool where you can launch any version of Minecraft (as long as you have the JAR) without having to set up a completely new environment.

There is a list view of all the JARs you have in the JAR folder. You select on and press "Launch". this will launch minecraft and you play that version.



"minecraft.jar" (the launcher) will automagically download if it is not in the folder when you open the application. You will also need to place your (or another) .minecraft folder inside the root of the program. Finally you need a folder called "jar" where the actual game jars are located.

here is the link to the download: http://xvicario.us/getfile.php?f=mclauncher-install.exe

Please comment

edit: And I just made a new Icon, what do you think of it?

I should have 1.3.1 maybe here...

Nice icon. This looks pretty handy, but I can't seem to find my old jars This will be helpful when I want to play older custom maps.

Wow, didn't even notice that, the link is fixed! Yeah its .NET so if you have Mono you can use that. I'll have a Linux build (a mono wrapped linux executable) in a bit. I have work in a half hour so I may release a linux executable after work (I work for 5 hours).

edit: actually it will not work in Mono right now because it uses a batch script. I'll upload a Linux version with a shiny new bash script after work.

It doesn't matter the location of the folder.  The batch script sets %APPDATA% to the current directory.  The mono wrapped application is a native linux executable, no mono required.  Its just that the application is a tad large (well not really large, but it won't be tiny).

I have no access to the source code right now.  Its not complicated at all.  Copy a JAR from the jar folder to the .minecraft/bin folder. Then call a script that launches minecraft.

edit: if anyone would mind writing a batch script for me that changes the location of the .minecraft folder to CD i could release a version right now for linux.

I could make interface things like buttons but make them similar to MC's GUI if you need those.
I've got both 1.8 prereleases on my HD.

This looks like a nice program, I've been collecting legal Minecraft's jars (with and without various mods) since 1.5.
The download link appears to be broken though, due to an ellipsis being inserted into it. I most likely wouldn't be able to use it anyway since it looks like a Windows-only program and I'm using Linux.

If you have a good CPU, search for "minecraft water shader", that's a great mod.

Why would you want to play an old version?

Why would you want to play an old version?

Historical Purposes and discontinued mods.
