"""
This script launches a Multiplayer "Multiworld" Mystery Game
.yaml files for all participating players should be placed in a /Players folder.
For every player a mystery game is rolled and a ROM created.
After generation the server is automatically launched.
It is still up to the host to forward the correct port (38281 by default) and distribute the roms to the players.
Regular Mystery has to work for this first, such as a ALTTP Base ROM and Enemizer Setup.
A guide can be found here: https://docs.google.com/document/d/19FoqUkuyStMqhOq8uGiocskMo1KMjOW4nEeG81xrKoI/edit
Configuration can be found in host.yaml
