Rhisis is an experimental FlyFF emulator built with C# and .NET Core 3.0

Rhisis

Rhisis is a FlyForFun V15 emulator built with C# 7 and the .NET Core Framework 3.0.

This project has been created for learning purposes about the network and game logic problematics on the server-side. We choose to use the Sylver.Network to manage our server connecitions because it provides a clients management system and also a robust packet management system entirely customisable.
