*Internet requirements are very light: any DSL or Cable internet connection should do. However, the internet demands rapidly increase as more players are added.

*Game disc images between players must have matching region and game revision. ISO, WBFS and other compression formats are OK. The player who do not have a game on one's end will face the "Game not found" error message. The game must be added to Dolphin game list if hasn't already.

*If hosting behind a firewall or router, port forwarding will be necessary. Dolphin operates on a Peer to Peer architecture, meaning that there is no master server. Instead you must manually setup and host games with people beforehand. This allows Dolphin's netplay to have the lowest possible latency.

*The player will need to ensure that all firewalls allow Dolphin to send and receive packets.
*All players should use the same Dolphin build, preferably the latest development build from [http://dolphin-emu.org http://dolphin-emu.org]. It is favorable to have a dedicated Dolphin profile for Netplay for the special settings and save files. It can be isolated from your main Dolphin profile by using [[Controlling the Global User Directory#Disable the Global User Directory for a Specific Build with "portable.txt"|"portable.txt"]] or create a [[Controlling the Global User Directory#Use a Shortcut to Use a Specific User Directory for a Specific Build|special shortcut]].

*Deterministic Dualcore Netplay is now merged into master. While compatibility is not perfect, it should allow more games to synchronize on dualcore with three exceptions. Games that require Skip EFB Access to CPU, Store EFB Copies to Texture Only and/or Disable XFB unchecked will are not guaranteed to sync up.  There are exceptions to this, but single core is recommended in games that require those settings. As well, some games are not compatible with deterministic dualcore netplay and will hang.  Disabling Dualcore will provide better compatibility but lower performance.

=== Becoming a host ===
In order to host, the player need to ensure that all firewalls allow Dolphin to send and receive packets. On top of that, if a computer is on a router, a port must be forwarded. For more instructions on how to handle specific routers, try [http://portforward.com/ portforward.com].
