Okay, so I would like to know how would u do a multiplayer game with someone? My son who is also a member newbie of this site told me that it would be the same way as when you do multiplayer on a gameboy...in which this is about multiplayer on the gameboy games. Well, I have never really played a gameboy, and I never knew how to do on it either. But if it is the same I would like to know how to do it, and the type of equipment or whatever that I would need with it.  
                       Thank you,

michaelbad : To play with someone else, you must go to the retro game room, find a game (can't be any Gameboy games), scroll down and click create a netplay session. People will then be able to join your session and play with you.

Actually, newbies can't create netplay sessions. They can't even join other people's netplay sessions unless they purchase a netplay ticket (from the Item Shop -> Accessories). You'll have to become regular members for this to work.

Regular members can join any open netplay sessions but cannot create them unless they have purchased the Netplay Ticket (see my above note on that).

So basically one of you will need a netplay ticket and you'll both want to be regular members for this to work. Then the one with the ticket creates and the other joins.

Of course if you got onto the same computer, you could do multiplayer locally by one of you using the player 1 controls for the emulator and the other using player 2's. This tends to work out better if at least one of you are using a controller, because sharing a keyboard would be difficult.
