* There will be issues with specific games or devices.
* Not all games work but most do.
* For games that do work you may have to try different video plugins
* Not all video plugins will work with every device and there could be glitches.

The netplay server is only supported in the pro version. To play games over the internet it requires a router with UPnP and being connected to the router. No UPnP is required to play games locally in the same WiFi network.
