Fácil amigos este fue un anti speed que inplemente hace muchos años en mi sourcer y lo tenía desactivado pero he visto mucha gente que anda usando hack así que lo volví a activar lo comparto para quienes les interese tenerlo en su sourcer directamente y no en el loader ya que en el loader se puede pasar desapercivido con un poco de cónocimiento
En mi caso yo lo tengo en el PacketHandler.cs que mi sourcer es un poco vieja y maneja dicha estructura a qui el código:
