Mario Kart: Double Dash!! on Dolphin Emulator is a blast, especially with friends. But how many players can actually join the race? The short answer: up to 4 players locally on one PC, just like the original GameCube. With online features through Dolphin’s netplay, you can also race with friends over the internet. This guide explains everything in simple terms so you can set up multiplayer fast and start drifting!
TL;DR: Mario Kart: Double Dash!! supports up to 4 local players on Dolphin Emulator. You can connect multiple controllers to one PC for split-screen racing. Dolphin also supports online multiplayer through netplay, letting you race with friends remotely. Setup is easy, and performance depends on your PC and settings.
How Many Players Can Play at Once?
Let’s keep it simple.
- 1 Player – Solo Grand Prix, Time Trials, or VS Mode.
- 2 Players – Split-screen multiplayer.
- 3 Players – Three-way split-screen.
- 4 Players – Four-way split-screen chaos.
The maximum number of players is 4 at the same time. This is exactly how it worked on the original Nintendo GameCube.
Dolphin Emulator does not increase this limit. It simply emulates the GameCube system. So, no 8-player race mods by default. Four racers. One screen. Total mayhem.
Local Multiplayer on Dolphin Emulator
Playing locally means everyone is in the same room. One PC. One screen (or TV). Multiple controllers.
What You Need
- A PC strong enough to run Dolphin smoothly
- Dolphin Emulator installed
- A Mario Kart: Double Dash!! game file (ISO or physical copy dumped legally)
- Up to 4 controllers
Controller Options
You have choices here. That’s the fun part.
- GameCube controller with adapter – Feels authentic.
- Xbox controller – Easy and comfortable.
- PlayStation controller – Works great.
- Keyboard – Not ideal, but possible.
Dolphin lets you configure each controller individually. You simply:
- Open Dolphin.
- Click on Controllers.
- Assign each port (Port 1–4) to a controller.
- Map the buttons.
Done. Now you are ready for multiplayer.
Does Split-Screen Affect Performance?
Yes. It can.
Here’s why. When you play with 4 players, the screen is split into four sections. That means your PC is rendering four camera views at the same time.
This requires more power.
If your PC is older or low-end, you might notice:
- Frame drops
- Small stutters
- Audio crackling
To improve performance, you can:
- Lower the internal resolution
- Disable anti-aliasing
- Close background apps
- Enable Dolphin’s performance hacks
A modern mid-range PC usually handles 4-player split-screen without issues.
Online Multiplayer with Netplay
Here’s where things get exciting.
Dolphin Emulator supports something called Netplay. This allows you to play with friends over the internet.
Even though Double Dash!! was not originally online, Dolphin makes it possible.
How Many Players Online?
You can have up to 4 players in the same race using netplay.
The total number is still limited to four because that’s how the game was designed.
You can mix setups too. For example:
- 2 players on one PC + 2 players on another PC
- 1 player per PC across four different locations
As long as the total racers equal four or less, it works.
How to Set Up Netplay
- Open Dolphin.
- Click Tools → Start Netplay.
- Host a session or join a session.
- Share the room ID with friends.
- Make sure everyone uses the same game version.
Stable internet is important. A wired connection is better than Wi-Fi.
Best Setup for 4-Player Fun
If you want the ultimate Double Dash!! party experience, try this:
- Connect your PC to a large TV.
- Use 4 GameCube controllers.
- Enable 1080p internal resolution.
- Use widescreen cheat codes (optional).
This keeps the retro feel while making the game look sharper.
Comparison Chart: Local vs Online Multiplayer
| Feature | Local Multiplayer | Online Netplay |
|---|---|---|
| Max Players | 4 | 4 |
| Internet Required | No | Yes |
| Same Screen | Yes (Split-screen) | No (Each player on own screen) |
| Setup Difficulty | Easy | Moderate |
| Best For | Parties and family nights | Playing with distant friends |
Can You Play with More Than 4 Players?
Short answer: No.
The game engine only supports four racers on screen at once.
Even if your PC is extremely powerful, the limit is coded into the game.
Some players rotate controllers between races. Others set up tournament brackets. That’s how you include more friends in the fun.
Tips for Smooth Multiplayer Sessions
Want zero drama and maximum fun? Follow these tips:
- Use wired controllers to reduce input lag.
- Test controllers before guests arrive.
- Save your controller profiles in Dolphin.
- Enable “Skip EFB Access from CPU” for performance boost.
- Use a wired internet connection for netplay.
Small adjustments make a big difference.
Is Multiplayer Still Fun Today?
Absolutely.
Mario Kart: Double Dash!! is special because of its two-characters-per-kart mechanic.
One player drives. The other throws items.
In multiplayer, this opens up crazy strategies:
- Switch positions mid-race.
- Chain special items unique to character pairs.
- Coordinate attacks in tight corners.
It feels different from other Mario Kart games. More teamwork. More shouting. More laughing.
