This is the netplay menu for connecting to another server as a client.
Manual entry - input the IP of the server you wish to connect to, and then specify the port numbers. Fields must be right-aligned. For example, 126.96.36.199 would be input like so: 026.098.124.136. Same goes for the port numbers.
Choose from list - selects a server to connect to from locally stored entries that you have specified.
Edit list - inputs a server's information, detailed below
These are the fields to specify upon editing your server list. Left and right will switch pages; up to 32 can be set. Numbers can be input as-is, for example you would use 188.8.131.52 without adding unnecessary zeroes. Put a name or something to differentiate which server it is in the comment field. Once you're finished go back and choose select from list and you will be able to more easily connect to the server in the future.
