XUPWUP's League of Legends patcher

Features

• On-the-fly archive building
• Multithreaded downloading
• Repair functionality
• Archive purging
  Removing all unneeded files from archives. This reduces the size of your install directory to more or less the same size as a clean install.
• Bundled Maestro server
• Self patching
• Supports EUW, NA, EUNE, BR, LAN, LAS, JP, OCE and PBE

Another important thing is speed. The patcher provided by Riot takes about 90 minutes to do a clean install. My patcher can do the same thing in 7 minutes (both on a 10MiB/s connection).

Requirements

• You must have Java installed.
• If you use this patcher to do a clean install, you may need to run Microsoft's DirectX installer.

Downloads

Decompress all files in the directory where you want LoL installed. The files should be in the same directory as the RADS directory. If no such directory exists, one will be created. You can put it in your old LoL directory, and it should work fine.

• Windows, Mac, Linux (4.1 MiB)

Acknowledgements

• Arcadestorm, for his help in figuring out the maestro protocol. Furthermore, his unfinished and abandoned League of Legends patcher was very useful for figuring out how everything worked.

FAQ

• Why is your patcher faster than riot's patcher?
  Mostly because I build the RAF archives on the fly, instead of downloading everything and then packing it into RAF files.
• Is your patcher open source?
  Yes!
• Why java?
  I like java.
