ACEmulator: Asheron's Call server emulator

ACEmulator rebuilds the Asheron's Call MMORPG server in C#, aiming to reproduce the game world as it was when the official servers closed in January 2017. The source implements the client network protocol (packets, game actions, events and messages), physics, world objects and a loader for the client's .dat files, backed by MySQL or MariaDB. Server options switch individual retail behaviours, such as door holding and fast buffing, on or off.
