Intro

Q: What is the goal of this project?

A: The goal of the GameServer project is to act as a server emulator for League of Legends version 4.20 (sln 0.0.1.67, project 0.0.1.7), or Preseason 5.

Q: Why choose v4.20?

A: v4.20 was the last version of League before Riot began rigorous work to encrypt their packet structure, specifically in game replays, which hindered this project's predecessor, IntWars in its efforts to provide a sandbox for the most current version of League. Thus, the version before major packet encryption was chosen as a base for LeagueSandbox, the (unofficial) successor to IntWars.

Q: What makes packet encryption so important?

A: When developing the GameServer, it was decided that the official League v4.20 GameClient (what users run to play the game) would be used to connect to the server. Because of this, it was required that the packets the GameClient was built for be emulated as well. To do so, extensive research was done on League Replay Files (LRF), which housed all the information sent from server to client during a match. When encryption was introduced, no only did it put a strain on the replay tools, as they were unable to handle the encryption, but it also meant all replays after v4.20 were severely corrupted, and research was halted as a result.
