# MapleStory2: reconstructing server packet structures

> Maple2 reconstructs a MapleStory2 server in C# and investigates the client's expected server-to-client packet layouts. Its PacketStructureResolver sends partial packets, uses client error reports to refine their structure, and saves the results for the server implementation.
