One of the biggest draws of this project is that it is a PC exclusive. Unlike official Nintendo titles locked behind console hardware, this fan game is designed specifically for computer play. This allows for:
For many fans, this represents the "definitive" way to play a fan-made Mario title, offering a level of freedom that console restrictions often prohibit.

Mario Multiverse (occasionally known as Super Fanmade Mario Bros.
) is a highly ambitious fan project developed primarily by neoarc. Designed as a PC-exclusive expansion of the "Mario Maker" concept, it allows players to create and share levels using assets from nearly every era of the franchise. The Story of the Game’s Development
The project began as a hobbyist endeavor by neoarc, who coded the engine from scratch to avoid technical limitations found in official Nintendo level editors. For years, the game remained in a "perpetual" closed beta, leading many in the community to believe it would never see a broad public release. This exclusivity fueled its legendary status among fans. However, on April 10, 2025, the first public demo was finally released, followed by subsequent updates that added new features like "Mario Singleverse" (offline mode) and "Demo Stage World". Key Features and Gameplay
Massive Game Styles: Unlike official games, it includes styles from Super Mario Land, Super Mario Land 2, Super Mario Bros. Special, and even an 8-bit Super Mario Odyssey theme.
Enemy & Theme Maker: Players can design their own pixel art for enemies, define unique AI behaviors, and create entirely custom themes.
Multitude of Characters: The game supports a wide variety of playable characters beyond Mario and Luigi, including characters with unique physics like Donkey Kong's "Jumpman" and various power-up forms like Penguin and Frog Mario.
Expansive Asset Library: As of early 2023, the game featured over 518 themes across 22 different gamestyles. How to Play and Download
While the game is technically PC exclusive (supporting Windows, with Linux/macOS support via Wine), obtaining it requires caution.
Official Public Demo: The safest way to play is through the public demos released periodically on the developer's official channels and the Mario Multiverse Discord.
Warning Against Leaks: The developer actively bans users caught downloading leaked or unofficial versions, as these files may also contain malware.
PC Requirements: Because the game is built for modern PCs to handle complex custom elements, it generally requires a Windows environment to run natively. Mario Multiverse by marioicecream - Itch.io
The fan game you are looking for, Mario Multiverse (also known as Super Fanmade Mario Bros.
or SFMB), is a popular PC-exclusive project developed by neoarc. It is designed as a massive level-creation tool that goes beyond Super Mario Maker by including elements from almost every major title in the franchise, including Super Mario Land and New Super Mario Bros.. How to Access and Play
While the full game was in a private beta phase for years, there are now public ways to experience it:
Public Demo: A public demo was officially released on April 10, 2025. You can find links and community updates through the official Neoarc YouTube channel or the project's Public Discord Server.
Mario Singleverse: An updated public demo that includes a "Demo Stage World" and a theme maker, allowing you to play and create without a full beta invite.
Browser-Based Creator: A simplified version titled "Mario Multiverse - A Platformer Creator" is available to play instantly via TurboWarp. Key Game Features One of the biggest draws of this project
Massive Variety: Includes 22 game styles and over 500 themes, ranging from 8-bit Super Mario Odyssey to Sonic.
Customization: Features a deep level editor with support for custom pixel art, enemy behavior presets (like Goombas), and multi-form transformations.
Exclusive Content: Includes items and power-ups not found in official Nintendo releases, as well as unique NPCs for storytelling. Important Safety Note
Be cautious of "leaked" versions or unofficial download sites (like certain Softendo links). Developers have warned that these may contain viruses and can result in a permanent ban from future official beta testing. Stick to the Official Reddit Community for verified download mirrors. This Super Mario Fan Game is INSANE!
Mario Multiverse is the ultimate tribute to the history of the Mushroom Kingdom. It is a massive, fan-driven project that expands the boundaries of traditional platforming. This guide explores what makes this PC-exclusive title a must-play for fans of the franchise. The Evolution of Fanmade Mario Games
The modding community has spent decades perfecting the art of the custom platformer. While official tools like Super Mario Maker gave players a taste of creation, they often felt limited by console hardware and strict building rules. Mario Multiverse was born from a desire to break those chains. It offers a level of depth and customisation that surpasses official releases, providing a sandbox that spans every era of Mario’s history. Why Mario Multiverse Stands Out
Unlike many clones, this project is built on a custom engine designed for pixel-perfect physics. It feels exactly like the classics while offering modern features that enhance the experience. Vast Asset Library
The game includes assets from Super Mario Bros., SMB3, Super Mario World, and even modern titles. You can mix and match themes to create levels that were previously impossible. Exclusive PC Features
By focusing on the PC, the developers utilized higher processing power to allow for more sprites on screen, complex scripting, and massive level layouts. It supports a wide range of controllers, ensuring that classic feel is preserved. Advanced Level Editor
The "Multiverse" name comes from the sheer scale of the editor. Creators can change gravity, implement custom power-ups, and design multi-layered worlds. It is a playground for both casual builders and hardcore designers. The Download and Installation Process
Finding a safe version of a fanmade project can be tricky. Because these are community-led efforts, they aren’t hosted on standard storefronts. Step 1: Locate the Community Hub
Most updates and legitimate download links are shared through official Discord servers or dedicated community forums. This ensures you are getting the latest build with the most recent bug fixes. Step 2: System Requirements
Since it is a PC exclusive, you don't need a high-end rig. Most modern laptops and desktops can run the game smoothly, though a dedicated GPU helps when playing levels with thousands of custom objects. Step 3: Controller Setup
While keyboard play is supported, the best way to experience Mario Multiverse is with a SNES-style or modern Pro Controller. Most versions include plug-and-play support for USB gamepads. Staying Safe Online
When searching for a Mario Multiverse download, always prioritize community-verified links. Avoid third-party "mirror" sites that require suspicious installers. The Mario fan community is very active in policing fake links to protect players from malware. The Future of the Multiverse
Mario Multiverse is constantly evolving. With a dedicated team of fans adding new themes, enemies, and mechanics, the game offers near-infinite replayability. Whether you want to play through thousands of community-made levels or build your own masterpiece, this PC exclusive is the definitive way to celebrate the legacy of Super Mario Bros.
Nintendo has a notorious history of issuing DMCA takedowns for fan games (see AM2R and Peach’s Untold Tale). Because PC is an open platform, developers can release the game anonymously via torrents, Discord servers, and file hosting sites without going through a digital storefront.
Furthermore, the technical scope of Mario Multiverse requires hardware that exceeds the Switch’s capabilities. The fan game utilizes real-time lighting, high-poly models, and particle effects that would cause a console to crash. It is PC exclusive because only a gaming PC (or Steam Deck) has the horsepower to render the "Multiverse" chaos smoothly.

The Mario Multiverse public demo is available for download on PC as of April 10, 2025. Developed primarily by neoarc, this fan-made project (also known as Super Fanmade Mario Bros.
) features a massive collection of level themes, custom pixel art, and physics engines that go beyond the official Super Mario Maker series. Key Features of the Public Demo
Comprehensive Level Maker: Includes diverse themes, background colors, and a wide array of items like power-ups, keys, and "gizmos" (magnets, trampolines, doors).
Custom Enemy & Boss Design: Users can create unique 2D versions of enemies, such as Wamps and mining-hat Goombas, and even build custom bosses.
Demo Stage World: Allows players to test levels directly without needing to download individual files.
Custom Themes: Features the ability for users to create and import their own entire game themes. Important Download & Access Notes
While the public demo was released in 2025, the full version of the game remains in a closed beta to avoid copyright issues and server overloads.
The cursor blinked in the command prompt window, a small white underscore against the black void. Leo held his breath, his finger hovering over the 'Enter' key.
He wasn’t installing a standard game. He wasn’t looking for Super Mario Odyssey or Wonder. He was after a legend. A myth whispered about in the deepest trenches of retro-gaming forums, on obscure Discord servers that required three-factor authentication just to peek inside.
They called it the "Multiverse Build."
The legend was simple: In the late 2000s, a disgruntled developer at Nintendo allegedly coded a prototype engine that allowed for infinite procedural generation. It wasn't just a level editor; it was a universe simulator. It supposedly linked the NES era, the SNES era, the 3D era, and the modern HD era into one seamless, chaotic reality. It was never released. It was scrubbed from existence.
Until tonight.
Leo had found the link on a board that had gone offline five minutes after he copied the text. The filename was a jumble of hexadecimal code, but the description was clear:
MARIO_MULTIVERSE_SUPER_FANMADE_MARIO_BROS_DOWNLOAD_PC_EXCLUSIVE.exe SIZE: 4.2 GB (Compressed) WARNING: HARDWARE REQUIREMENTS UNKNOWN. PLAY AT OWN RISK.
"PC Exclusive," Leo muttered, grinning. "Of course. No console could handle this."
He hit Enter.
The extraction process was violent. His high-end rig, usually quiet as a mouse, roared. The fans spun up to a jet-engine pitch. The progress bar didn't move linearly; it jittered, glitched, and occasionally flashed images—a sprite of Mario from Super Mario Bros. 3, a texture of a Goomba from 64, a polygon of Princess Peach from Sunshine.
Finally, a prompt appeared: READY PLAYER ONE? [Y/N]
Leo typed 'Y'.
The screen went black. Then, a sound. Not the cheerful "It’s-a me, Mario!" but a distorted, echoing version of the coin-collecting sound, stretched out until it sounded like a synth note. The Mario Multiverse public demo is available for
The game launched.
There were no menus. No "Start Game," no "Options." Leo’s character—a pixel-perfect sprite of 8-bit Mario—dropped directly into a world that made his eyes hurt.
He was standing on a green pipe, but the pipe wasn't drawn; it was a photo-realistic 3D model. The ground beneath him was the beige blocks of the original 1985 game, but the background was the shifting water of Super Mario World, overlaid with the starry sky of Galaxy.
"Whoa," Leo whispered.
He tapped the 'D' key to move right.
The transition was seamless. As Mario walked, he changed. Crossing an invisible threshold, the 8-bit sprite stretched, gained shading, and became the 16-bit Mario from World. A few steps later, he popped into a low-poly 3D model, sliding on a slippery ice physics engine that felt exactly like Mario 64.
This was the Multiverse. It wasn't a rom-hack; it was a DNA splice of gaming history.
Leo encountered his first enemy. It was a Goomba, but it was wrong. It had the shape of a modern Goomba, but the face of the original 8-bit sprite, pixelated and angry. It charged him.
Leo instinctively jumped, but the physics were shifting. The gravity had changed to the heavy pull of Galaxy. He floated too high, hovering over the enemy, and landed with a thwomp sound effect from Mario Bros. Arcade.
Then, the text box appeared. It wasn't the usual polite dialogue. The font was jagged, red.
SECTOR: NULL. ANOMALY DETECTED. UNIVERSE INTEGRITY: 42%.
"Is this a story mode?" Leo wondered, pushing forward.
He reached a castle. It wasn't the usual flat facade. It was a terrifying fusion of Princess Peach’s Castle from 64 and the menacing fortresses of Mario Maker. He walked through the painting that served as a door.
Inside, the game broke.
Leo’s screen fractured. He was suddenly in a first-person perspective—a view never seen in a mainline Mario game. He was looking down a corridor of infinite doors.
He opened the first door. World 1-1. Perfect. Pristine. He opened the second. World 1-1. But it was underwater. The Goombas swam awkwardly. He opened the third. World 1-1. But the graphics were hyper-realistic. The pipes were rusted metal; the bricks were crumbling stone. The realism was uncanny, almost frightening.
He stepped into this third world. The "PC Exclusive" tag suddenly made sense. The lighting was ray
