User:P.i./Brawl Online Guide

This guide explains how to play Super Smash Bros. Brawl online, either on a personal computer using Dolphin, or on a Wii or Wii U using Wiimmfi.

Dolphin netplay guide (PC)
First, make sure all players have the current netplay Dolphin build.


 * Netplay Dolphin for Windows
 * Netplay Dolphin for Mac
 * Netplay Dolphin for Linux

Note: Both players must use the exact same Dolphin version (cross-platform is fine). Note for Mac users: The current build of Dolphin struggles to work on Macs using an Apple CPU (M1 or M2), due to the build being designed for Intel CPUs. If your Mac has an Intel CPU, Dolphin will work but if you have an M1/M2 CPU, Dolphin may have issues.

You must also have a Brawl ISO. You can back up your own copy legally. Do not ask where to download ISOs.

In order to add the game to Dolphin, either move the .iso file to the Dolphin "Games" folder, or go to Dolphin Configuration -> Paths and add the game's folder there.

Ensure your game backup is correct by verifying the MD5 checksum in Dolphin. These are the valid MD5 hashes:
 * 1) Right click the game in Dolphin's game list and go to Properties.
 * 2) Go to the Info tab.
 * 3) Next to "MD5 Checksum", click "Compute". This will take a a couple minutes.
 * 1.01: d18726e6dfdc8bdbdad540b561051087
 * 1.02: 52ce7160ced2505ad5e397477d0ea4fe

You can also compute the checksum of every player's game at once from the Netplay window.

If you have Brawl version 1.02, you can use this patcher to convert it to version 1.01.

Many configuration options in Dolphin must be specified exactly in order for netplay to work and to minimize desyncs. The Netplay Dolphin links above should mostly be preconfigured, but you might have to double check some settings.

Additional settings (no screenshots):
 * "Insert SD card" under Dolphin Configuration -> Wii should be off.
 * If necessary, add the directory containing the Brawl ISO in under Dolphin Configuration -> Paths.
 * Turn on "Scaled EFB Copy" under Graphics Configuration -> Enhancements.

For controllers, most players use real GameCube controllers with an adapter.
 * General Dolphin controller guide
 * SmashLadder controller guide

Netplay settings (no screenshot):

Every time you use Dolphin netplay, you must set the "Minimum Buffer" to approximately ping (in ms) / 8. Common values range from 4 (extremely good) to 20 (transatlantic lag). If the game isn't hitting 60 fps, try raising the buffer. Lower values are better, but if the buffer is too low the game won't run smoothly.

Spectating can be done by having a third person join the game, and clicking "Assign Controller Ports" to remove the spectator's port (this will prevent the spectator from causing lag for the other players). Spectators should not host.

Recording replays can be done by checking the "Record input" box. These files can only be played back in Dolphin, but they are very small and recording them has no performance impact.

Wiimmfi guide (Wii/Wii U)
In order to play online on a Wii or Wii U, go into the Wii internet settings and put 95.217.77.181 as the Primary DNS.


 * 1) Go into Wii Options -> Wii Settings -> Internet -> Connection Settings -> Change Settings.
 * 2) Go to the "Auto-Obtain DNS" screen.
 * 3) Put 95.217.77.181 as the "Primary DNS".
 * 4) Leave the Secondary DNS as "000.000.000.000".
 * 5) Click "Confirm".
 * 6) Click "Save".

For a video tutorial, see How to play Mario Kart Wii online on Wiimmfi with JUST a custom DNS (Wii/WiiU, no Homebrew, no SD). There are also other methods of loading Wiimmfi.

To use a wired connection on Wii or Wii U, see the lag guide (wired connection section).

For mods, transferring replays, etc., you will need a 2GB SD card. Larger SD cards are not compatible with the Wii without mods.
 * Transcend 2 GB SD Flash Memory Card (TS2GSDC) (amazon.com)

Wiimmfi should work with your existing Brawl save file. However, if you don't have everything unlocked, you can follow these steps (by SmashBoards member pidgezero_one):
 * 1) Erase your Brawl save from your wii. You can do this in the wii system menu. You do NOT need to format your wii.
 * 2) Download the save file here: http://www.mediafire.com/file/zuq8cnbx18n7lnq/brawlsave.zip
 * 3) Put the "private" folder to the root of your SD card
 * 4) put the SD card in the Wii
 * 5) go to Wii settings from the home menu > Data management > Save data > Wii > SD card, and copy or move the file onto your Wii.
 * 6) You now have a brand new, never-before-wified save file! (Thanks swordgard!)

Here is a small set of recommended basic Gecko codes for Wiimmfi. These codes aren't necessary, but they make the game more playable or convenient. They won't cause desyncs even if your opponent doesn't have them. (Note: these codes aren't used on Dolphin netplay.)

Playing between Dolphin and Wiimmfi (optional)
Dolphin is not allowed on Wiimmfi without dumping the NAND data from a real Wii or Wii U.

Once you have dumped the NAND:
 * 1) Download the Auto Wiimmfi Patcher and extract it
 * 2) Make a complete copy of the Dolphin directory and rename it "Dolphin-Wiimmfi" or such
 * 3) Start Dolphin-Wiimmfi
 * 4) Right click the Brawl ISO, go to Properties, and turn off the "Global Brawl Netplay Settings" and the "Disable Challenger Approaches" codes
 * 5) Right click the Brawl ISO in Dolphin and select "Set as default ISO"
 * 6) Go into the Dolphin config and add a path to the Wiimmfi Patcher directory (which should contain a file "boot.dol")
 * 7) Start boot.dol to play. Once Brawl starts, go to Nintendo WFC on the main menu.

Connection issues
If you can't join a game or others can't join your game in Dolphin, you may be using a different Dolphin version.

If you try hosting a game and other people can't join your game (on Dolphin or Wiimmfi), you may need to turn on port forwarding or DMZ on your router. On Dolphin, you can set the port to 2626 and forward this port on your router. Or try having the other person host.

If you get a connection error on Wiimmfi, check the meaning of the error code here.

If you join a game, but have "Status: game missing" by your name in Dolphin netplay, you either need to add the game folder's path in Dolphin Configuration, or verify the game's MD5 checksum to make sure you have the right version.

If your game has the wrong MD5 checksum, either you have the wrong version, or it could be corrupted. Compressed or .nkit format versions do not work on netplay.

If the game runs choppy in Dolphin, first raise the "minimum buffer" if you are in netplay. If that doesn't help, try testing offline. You might have to reduce the graphical settings or get a faster computer.

If you have bad lag, see the lag guide (troubleshooting section).

If your game desyncs (you and the other player see different things happening in the game), it might be caused by mismatched mods or codes (on Wiimmfi or Dolphin), or by mismatched settings in Dolphin. Try turning off any mods. On Dolphin, refer to the settings above. Desyncs can be caused by either player, so try playing other people in order to tell. It's rare, but sometimes correctly configured Dolphin or even Wiimmfi will desync and all you can do is restart the game.
