This small windows PC app notifies you when someone is hosting an arcade game via Netplay on Retroarch so you can join anyway you want (using Retroarch, CloudBox or any other frontend you use).
For better compatibility it only notifies about games that are:
Connectable
Password free
Retroarch 1.20 / 1.21
FinalBurn Neo v1.0.0.03
It also allows you to add nicknames to a "friend" list, the app will use a different sound for those.
To easily join or host any game at any time you can simply use the free no config/account required frontend CloudBox Arcade! details and download link here: https://www.patreon.com/posts/cloudbox-arcade-139880506
