[PC/Dolphin] Tatsunoko vs. Capcom: Ultimate All-Stars - Online Netplay Setup Guide
This guide explains how to play Tatsunoko vs. Capcom: Ultimate All-Stars online using Dolphin Emulator's Netplay feature.
The game's original Nintendo Wi-Fi Connection service is no longer available. Dolphin Netplay provides an alternative method by allowing the game's local multiplayer mode to be played between computers over the internet.
For this guide, we recommend using GameCube controller emulation whenever possible because Tatsunoko vs. Capcom supports GameCube controllers and this provides a relatively straightforward configuration for Dolphin Netplay.
==================================================
WHAT YOU WILL NEED
==================================================
ΓÇó Dolphin Emulator for desktop
ΓÇó Your own legally dumped copy of Tatsunoko vs. Capcom: Ultimate All-Stars
ΓÇó A controller or other configured input device
ΓÇó A stable internet connection
ΓÇó Another player using the same Dolphin version and matching game version
==================================================
IMPORTANT GAME FILE NOTICE
==================================================
Dolphin does not provide commercial Wii game images.
SGAWeb does not host, distribute, or provide download links to copyrighted Wii game images, ISOs, ROMs, or other copyrighted game files.
Each player should obtain and dump their own copy of Tatsunoko vs. Capcom: Ultimate All-Stars.
This tutorial covers only Dolphin Emulator configuration and Netplay.
==================================================
STEP 1 - DOWNLOAD DOLPHIN
==================================================
Download Dolphin Emulator from the official Dolphin website:
Dolphin Emulator - Official Website
Install or extract Dolphin according to the instructions for your operating system.
All players participating in Netplay should use the same Dolphin version.
Using different Dolphin versions can prevent Netplay from working correctly or cause synchronization problems.
==================================================
STEP 2 - ADD TATSUNOKO VS. CAPCOM TO DOLPHIN
==================================================
Add your legally dumped copy of:
Tatsunoko vs. Capcom: Ultimate All-Stars
to Dolphin's game library.
Launch the game normally before attempting Netplay.
Make sure that:
ΓÇó The game starts correctly.
ΓÇó Gameplay runs at normal speed.
ΓÇó Your controller works.
ΓÇó There are no major graphical or performance problems.
Dolphin currently lists Tatsunoko vs. Capcom: Ultimate All-Stars as having excellent compatibility and the game normally does not require special settings.
==================================================
STEP 3 - MAKE SURE BOTH PLAYERS' COPIES MATCH
==================================================
This is extremely important for Dolphin Netplay.
Every player should use:
ΓÇó The same Dolphin version
ΓÇó The same game region
ΓÇó The same game revision
ΓÇó Preferably identical game dumps
For example, do not have one player using the North American version while another player uses the European version.
Dolphin includes checksum functionality that can help players verify that their game files match.
Mismatched files or emulator configurations can cause desynchronization during Netplay.
==================================================
STEP 4 - CONFIGURE YOUR CONTROLLER
==================================================
Open Dolphin and select:
Controllers
Tatsunoko vs. Capcom supports GameCube controllers, Wii Remotes, and other controller configurations.
For this Netplay guide, using an emulated GameCube controller is recommended when possible.
Configure:
GameCube Controller Port 1
as:
Standard Controller
Then configure your physical controller or keyboard.
Test your buttons before starting Netplay.
Each player should configure their own controller locally.
When one player is using each computer, Dolphin can automatically assign each participant's configured controller to the appropriate Netplay controller port.
==================================================
STEP 5 - OPEN DOLPHIN NETPLAY
==================================================
From Dolphin's main menu select:
Tools -> Start NetPlay
Depending on your Dolphin version, you may see options for:
ΓÇó Hosting
ΓÇó Connecting
ΓÇó Traversal Server
ΓÇó Direct Connection
ΓÇó Netplay Server Browser
For most players, the Traversal Server is the easiest place to begin because it can often establish connections without manually configuring router port forwarding.
==================================================
STEP 6 - HOST A NETPLAY SESSION
==================================================
One player must act as the host.
From the Netplay window:
1. Select the Host tab.
2. Select Tatsunoko vs. Capcom: Ultimate All-Stars.
3. Choose the Traversal Server connection method.
4. Start the Netplay room.
Dolphin will provide the host with a traversal code.
Send this code privately to the other player.
The traversal code allows the other player to connect to your Netplay session without requiring you to publicly share your IP address.
==================================================
STEP 7 - JOIN A NETPLAY SESSION
==================================================
The second player should open:
Tools -> Start NetPlay
Select the connection/join option and choose the Traversal Server method.
Enter the traversal code supplied by the host.
Once connected, both players should appear in the Netplay room.
Do not launch the game separately.
Wait for the host to start the game through the Netplay window.
==================================================
STEP 8 - CHECK CONTROLLER ASSIGNMENTS
==================================================
Before starting the game, the host should verify the Netplay controller assignments.
For a normal two-player match:
Player 1 -> Controller Port 1
Player 2 -> Controller Port 2
Dolphin normally handles standard controller assignments automatically when each player is connecting from a separate computer.
Both players should confirm that their controls work correctly after the game starts.
==================================================
STEP 9 - CONFIGURE THE NETPLAY BUFFER
==================================================
Dolphin Netplay uses an input buffer to compensate for network latency.
If the buffer is too low, gameplay may stutter or slow down.
Dolphin's documentation provides a useful starting point of approximately:
1 buffer unit for every 15 ms of latency per client.
For example, a two-player connection around 50 ms may work around:
3-4 buffer
This is only a starting point.
Increase or decrease the buffer depending on connection quality and game performance.
==================================================
STEP 10 - START TATSUNOKO VS. CAPCOM
==================================================
Once both players are connected and controllers are assigned, the host can start the game.
Navigate to the game's local multiplayer/VS mode.
Because Dolphin Netplay synchronizes the local multiplayer session between the participating computers, you do not need to use Tatsunoko vs. Capcom's original Nintendo Wi-Fi Connection menu.
Choose your characters and begin the match.
==================================================
TROUBLESHOOTING DESYNCS
==================================================
A desync occurs when the players' emulators stop representing the same game state.
If this happens, verify:
ΓÇó Both players use the exact same Dolphin version.
ΓÇó Both players use the same game region and revision.
ΓÇó Both players have matching game dumps.
ΓÇó Players have not enabled conflicting emulator settings or modifications.
Dolphin's Netplay Checksum feature can be used to verify matching game files.
Keeping Dolphin close to its default configuration is recommended when initially setting up Netplay.
==================================================
CONNECTION TROUBLESHOOTING
==================================================
If another player cannot connect:
ΓÇó Allow Dolphin through your operating system firewall.
ΓÇó Try the Traversal Server connection method.
ΓÇó Restart Dolphin and recreate the Netplay room.
ΓÇó Verify both players are using compatible Dolphin versions.
ΓÇó Check whether either player's network uses a Strict NAT.
Some Strict NAT configurations may prevent the Traversal Server from establishing the connection.
In those situations, the host may need to configure port forwarding and use Dolphin's Direct Connection option.
Router configuration varies by manufacturer, so consult the documentation for your particular router if port forwarding becomes necessary.
==================================================
NETWORK PERFORMANCE
==================================================
For the best Netplay experience:
ΓÇó Use Ethernet instead of Wi-Fi when possible.
ΓÇó Avoid large downloads or uploads while playing.
ΓÇó Choose a host with a reliable internet connection.
ΓÇó Keep the Netplay buffer appropriate for the players' latency.
Network latency directly affects how responsive Netplay can feel.
==================================================
ORIGINAL ONLINE SERVICE NOTICE
==================================================
Tatsunoko vs. Capcom: Ultimate All-Stars originally included Nintendo Wi-Fi Connection multiplayer.
That original online service was discontinued in 2014.
This tutorial does not attempt to reconnect to the original Nintendo Wi-Fi Connection service.
Instead, Dolphin Netplay synchronizes the game's local multiplayer mode over the internet.
