Experience Super Mario Sunshine like never before with a 10-player online mode and new multiplayer features.
Super Mario Sunshine online mod brings 10-player multiplayer and hide-and-seek for a fresh take on the GameCube classic.
A New Era for Super Mario Sunshine Multiplayer
What if you could romp through Isle Delfino with nine friends in tow? That’s not just a pipe dream anymore—thanks to a bold new mod, Super Mario Sunshine’s sun-soaked world is now a bustling multiplayer playground. I’ll admit, when I first heard about the idea of a 10-player online mode for this GameCube classic, I was both giddy and skeptical. Could it really work? How would the platforming mayhem play out with that many Marios (and not-Marios) sprinting about?

Better Super Mario Sunshine Online: What’s New?
Jumping straight into the action, the new modification is called Better Super Mario Sunshine Online, crafted by modder Daytendo 64. This isn’t some quick patch or a mere curiosity—it’s a full-blown overhaul. With it, you and up to nine pals can tackle Sunshine’s story together, or, if you’re feeling sneaky, face off in a dedicated hide-and-seek mode.
I have to admit, my first impression was that this would be a technical mess. After all, Super Mario Sunshine was never meant to juggle so many players online. But the mod manages some impressive feats of synchronization.
How Multiplayer Works: Co-op and Hide-and-Seek
The co-op mode isn’t just a cosmetic add-on. The mod actively syncs up your progress: collected Shine Sprites and Blue Coins, changes to Delfino Plaza, and even story progression carry over for everyone. Even better, if a friend joins late, the game catches them up automatically, avoiding that awkward “wait, what’s going on?” moment.

But the real hidden gem here? Hide-and-seek. At the start of each round, the seeker can be chosen manually or by the game, and the hiders have precious seconds to find a perfect spot somewhere in the map. Want things a little less predictable? The next round’s map can be randomized, so you’re never quite sure where you’ll be dashing off to next.
And if you want to see the chaos in action, check out the release trailer (it perfectly captures the energy and unpredictability):
Fifteen Playable Characters, and Not Just Mario
One of the most surprising delights: the roster. Sure, Mario’s here (it’d be weird if he wasn’t), but you can also slip into the shoes of Waluigi, Sonic, and Shadow. That’s right—Sonic in Super Mario Sunshine! Seeing those familiar faces from across gaming sprinting around Isle Delfino is both hilarious and strangely fitting.
“The modder also brought in a slew of fixes and tweaks to polish the whole experience.”
— Daytendo 64
Of course, it’s not just about adding new faces. Daytendo 64 has patched up a slew of network bugs and tightened up the gameplay, making the whole experience feel smoother than you’d expect from a fan-made expansion.
Why Create a New Mod? The Story Behind the Project
Every good mod has an origin story, and this one’s no exception. Daytendo 64 started this project after feeling let down by the previous multiplayer effort, Super Mario Sunshine Online. That mod had suffered from a lack of updates, unstable connections, and a frustrating number of bugs. Rather than wait for someone else to fix things, Daytendo rolled up their sleeves and started anew.
It’s a bold move, and I found myself rooting for this underdog project, especially given how ambitious it is to overhaul a game from 2002 with modern online play.
How to Play: Requirements and Setup
Curious to try it for yourself? Here’s what you need:
- A PC with the Dolphin emulator.
- A copy of the GameCube version of Super Mario Sunshine (NTSC-U—the American release only).
- The Better Super Mario Sunshine Online mod, downloadable from GameBanana.
- Either Radmin VPN for easy connection or some port forwarding wizardry if you’re feeling tech-savvy.
It’s worth noting—there’s a little technical barrier for entry here. I did wonder if that would put off some less tech-inclined players. Still, for fans hungry for something fresh in their favorite vacation-themed platformer, it’s definitely worth the effort.
Fan Mods and the Joy of Multiplayer Revivals
This isn’t the first time fans have breathed new multiplayer life into a beloved classic. In fact, there’s a growing trend of modders adding co-op and versus modes to games that launched in the single-player era. For instance, someone previously made a three-player co-op mod for The Lost Vikings on SNES.
These projects aren’t always perfect—sometimes multiplayer can feel bolted on, or technical hiccups get in the way of fun. I was wary that this Sunshine mod might fall into that trap, but it’s clear the developer genuinely cares about playability. Still, I did run into a minor issue with connection stability during my first session, though a quick restart seemed to solve it.
The Verdict: Sunshine With Friends—Worth the Hype?
Wrapping up my time with Better Super Mario Sunshine Online, I found myself pleasantly surprised. Sure, the occasional glitch or hiccup reminded me that this is a labor of love, not a polished commercial release. But the simple joy of exploring classic levels with a crowd of familiar and unexpected characters more than made up for it.
I went in doubtful, braced for chaos, but ended up seeing a side of Isle Delfino I never expected: one where laughter, friendly sabotage, and wild multiplayer antics steal the spotlight from the sun itself.
Conclusion
With the Better Super Mario Sunshine Online mod, a game that once felt like a solitary summer vacation evolves into a lively group adventure. Not every moment is seamless, but even the rough edges can make for lasting memories. Have you tried multiplayer mods for your favorite classics, or does this inspire you to dive in for the first time?
