## Overview

This repository provides Episode 6 support for Shaiya through injected client and server-side DLLs, plus a login hook and database-facing components. The visible server entry point installs packet, user, item, and world hooks and loads game configuration; the login hook parameterizes a login procedure call. The client tree contains input, player/world, camera, chat, and skill modules, but their runtime connections are not shown in the excerpts. Several relationships are therefore omitted rather than inferred.

Main entry points: [`sdev/src/main.cpp`](https://github.com/kurtekat/shaiya-episode-6/blob/main/sdev/src/main.cpp) (Hook Startup), [`sdev-login/src/main.cpp`](https://github.com/kurtekat/shaiya-episode-6/blob/main/sdev-login/src/main.cpp) (Login Hook), [`sdev-login/include/shaiya/SDatabase.cpp`](https://github.com/kurtekat/shaiya-episode-6/blob/main/sdev-login/include/shaiya/SDatabase.cpp) (Login SQL API), [`sdev-client/src/dllmain.cpp`](https://github.com/kurtekat/shaiya-episode-6/blob/main/sdev-client/src/dllmain.cpp) (Client DLL Entry)
