As some people may know, I've been making my own custom launcher for a long time now, primarily for my Minecraft server, but I'm glad to post the latest version publicly!

(I make WorldEdit, WorldGuard, and some other mods for Minecraft.)

What am I looking at?

This is a custom Minecraft launcher that allows you to one-click install mods, letting you enable and re-order them at any time. It is small and just as easy to use as the official launcher, and it's really clean.

So what's this about mods?

• Install both ModLoader and non-ModLoader mods easily, both the same way, by clicking "Install" and choosing the file.
  
• Never touch META-INF or minecraft.jar. Just click, select the mod .zip, and then install.
  
• You don't need a custom mod made for the launcher. The launcher tries to be smart and figures how the .zip is organized on its own.

Wait! There's more to it:

• Easily change Java RAM usage options and other game-related settings.
  
• Switch between multiple Minecraft accounts and remember their passwords.
  
• Switch between different configurations, each with different settings.
  
• Switch between different .jar files to run, each with different lists of mods.
  
• Quick to load, clean news display. Can be disabled anyway.
  
• Quickly connect to servers you use by right clicking the Play button*.
  
• Supports updating Minecraft, downloading only files that were updated.
  
• Having problems? Open the console and view error messages. It won't close if Minecraft dies.
  
• Supports digital signature verification for everything, making sure all the files you download with the launcher were not tampered with.
  
• More options to be found in the options dialog.
  
• Open source! Don't trust some Internet person giving you a launcher? Compile it yourself.

*Currently requires manually editing the configuration file.

Download:

FOR THE TIME BEING, please get "developer versions" from
http://build.sk89q.c...b/SKMCLauncher/

OLD VERSIONS:

• v3.1.5 - .EXE for
  
• v3.1.5 - .JAR for
  
• v3.1.5 - .APP coming soon for

If you find it useful, you can pay for some coffee! Find the source code on GitHub.

NOTE: If the .exe gives you a virus warning, use the .jar. The .exe simply wraps around the .jar and that is considered suspicious by some particularly trigger happy anti-virus programs.

How do I install a mod?

Open the "Addons" window, click "Install...", and select the .zip or .jar that you have downloaded.

• This works for most mods, but if a mod doesn't work, please post about it here.
  
• You may need to still extract files to your Minecraft folder for some mods.
  
• Be sure to put mods that are depended on by others (like ModLoader) near the top of the list.
  
• If a mod uses an installer, try the version without an uninstaller.

It is possible to add files to minecraft.jar (the old way of installing mods) in addition to setting up addons in the launcher, but minecraft.jar mods will always be overridden by any addons in the launcher (as far as the .class files go).

Technical Information:

• Mods are loaded on the classpath directly from the original .jar or .zip. All mod archive files are placed in addons/<jar name>/ within the Minecraft folder.
  
• For .zips where the .class files are placed in some sub-directory of the .zip, the files will be moved up (including any resources in adjacent folders) to be at root.
  
• Package sealing and package certificate checks have all been disabled.
  
• The launcher primarily works through a custom classloader that disables various class loading mechanics and uses some compatibility code to get ModLoader mods to load. This means that minecraft.jar is never modified.

Changes:

• v3.1.1: Fixed some mod installation issues.

You've done it again sk89q! You are truly one of the better people in the minecraft community.

[gretar123]

Awesome!

[fuzetsu490]

Looks great!
This is definitely my default launcher from now on.

[md_5]

Downloading now, I hope it lives up to my expectations, looks really good

EDIT: And yes it does, amazing job sk, I will be sure to make some pull requests.

EDIT AGAIN: It works really well and I look forward to working with sk89q to iron out the bugs and make it even better.

I love that it's stripped down graphically compared to magic launcher. One thing that is missed is that magic launcher does some checks in the addons for possible incompatibilities. Other than that, it looks like a favorable replacement.

THANK YOU!!!!!!!!!!!!!!

[sk89q]

I posted v3.1.1 which fixed some issues with some mods not being properly scanned.

[citricsquid]

impressive work!

Nice launcher, thanks.

Suggestion: A 'launch maximised' option (not full screen). I always play in a maximised window so I can still see my taskbar.

Possible bug: I tried out the full screen option and not only did it not launch in full screen, but after I maximised the window the game continued to play in a small part of the window in the bottom left of the screen.

Do mods that modify things outside of minecraft.jar work properly?
E.G. MAtmos' files in resources and the like.

[Puremin0rez]

Whenever I make a new configuration, logging in will just stay at "Connecting to login.minecraft.net" forever. It does NOT do this on the default configuration.

[snowy007]

It works nice.
Both modloader and the Worldedit CUI are installed fine.

But then.. there is this other mod. The Water shader mod.(http://www.minecraft...ader-alpha-v5b/)
This mod does not only require files to be added to the minecraft.jar but also requires you to add the included 'shaders' folder to your 'bin' folder. So just for information, this mod and perhaps other mods that require more than changing the minecraft.jar are incompatible with the mod installer of this launcher.
Don't know if this is possible or easy to include, but i just thought i'd let you know.

[Jekyll]

this is great! I hope this can replace the batch-scripts I use
for switching configuration files and login-credentials before launch

(we play with different accounts and settings on the same computer, so I basically have folders with sets of all the different config-files and overwrite the 'real' file with it's person-specific counterpart when starting the script, launch the jar, and write back the changes to the person-specific file after minecraft has closed sucessfully)

[JeremyisBetter]

How do I use the two different .jars on only one config?
EDIT: Never mind, I figured it out by myself but thanks for the awesome launcher

I'll look into having that added. The fullscreen option is passed directly to Minecraft, so maybe Minecraft doesn't take it well (anymore?).

You'd have to extract the files manually but it should work.

The launch thread must be crashing. I'll have to look into it.

I'm hoping to rectify this shortly, so you can intervene when necessary (without getting too dirty) to get a given mod installed.
