MultiMC is currently the recommended launcher for installing mods on legacy Minecraft. Download

• Many separate instances can easily be created for almost any version.
• Mods and their install order can be adjusted with no class dragging required.
• Logs for both MC and mods are easy to find and feature one click upload for debugging.

Notes:

• Does not completely override minecraft directory, so some mods will still look in .minecraft for config/resources.

PyMCL is a new launcher that allows you to install legacy modpacks automatically. Download
Currently available packs include AetherMP, Technic Pack, AdventureCraft and more.

Notes:

• Relatively unstable compared to MultiMC.
