Before you go writing a negative review on how the server “Won’t communicate with your iPod” first read up on how to find an IP address. It does NOT find your computer automatically. You are supposed to enter in your IP address while on the same network. If you don’t know how to do this, google it. 

As for the Windows version having troubles with the D-pad, this is a limitation of the development software that is again temporary - it is unable to interpret the regular arrow keys, and instead must use the arrow keys on the number pad. While most emulators are ok with this, some like FCE ultra and Kega Fusion only will respond to the regular arrows. To remedy this map the d-pad to the numberpad arrows until the new version is released.
