Mario in Elden Ring, Minecraft in GTA: How These Mods Work

All that time choosing the right weapon for Radagon of the Golden Order, and somebody decides to send Mario in with a ground pound. We get together for our weekday gaming nights to have fun, and experimenting with mods is part of that. Seeing people build Minecraft walls in Los Santos and swing through Gotham as Spider-Man showed us how far these experiments were going, so we knew we had to cover them on TGK, figure out how they work, who’s making them, and what we can try.

Quick Answer

In Minecraft × GTA V, both games run on the same PC, with a Fabric mod in Minecraft and a ScriptHookV plugin in GTA exchanging camera positions, controls and gameplay events through a local connection called a WebSocket. ReShade combines their graphics, while the plugin creates solid obstacles in GTA wherever you place Minecraft blocks, so cars can really hit your walls.

ER Mario brings Mario’s movement into Elden Ring through the me3 mod loader and libsm64, a software library that runs his original physics and animations. The mod supplies information about Elden Ring’s floors and walls so his jumps respond to the world around him, while his attacks are connected to its enemies. Coding agents can help write and fix that connecting code, with projects such as Universal Modder providing tools, instructions and previous findings for them to work from.

Why people keep sharing these videos

You know what Minecraft looks like, and you know what usually happens in GTA, so seeing the police fighting Minecraft mobs makes sense immediately. The same goes for Spider-Man swinging through Gotham or CJ grinding along a rail with Skate 3’s controls. You can understand the appeal without knowing anything about how a game engine works.

Seeing the idea work makes you wonder what else could be combined, and the next clip might answer that with something even stranger. We enjoy messing around with games, so it’s easy to see why these videos keep getting passed around our group.

Which mashups can you try?

How we checked: We checked the creators’ documentation, release pages and setup requirements on 11 October 2026. Our TGK mod experiments prompted this feature; for these specific releases, we’re reporting from the original projects’ documentation and haven’t run our own play tests.

The Awesome Game Mashups catalogue is a useful place to find more examples. It distinguishes releases from experimental code and unconfirmed sightings, so you can follow an interesting clip back to something more useful than another repost.

Mario in Elden Ring

Deltaroo’s ER Mario brings across Super Mario 64’s triple jumps, wall kicks, long jumps and ground pounds. Mario can punch and kick enemies, throw them, and swing staggered bosses around by the tail. He also gets the familiar eight-part health meter, coins and Lakitu camera, while Elden Ring’s usual character stats don’t determine his health or damage.

That gives you a different set of options in a world built around the Tarnished. Walls and ledges become places to try Mario’s moves, and ground-pounding an enemy is a fairly big departure from choosing another sword. The setting remains Elden Ring, so don’t expect a collection of imported Mario levels.

The mod uses libsm64, which makes Mario’s movement and animation code available to other software. It receives information about Elden Ring’s floors, walls and other solid surfaces so Mario can move against them properly. The Tarnished remains underneath as a hidden stand-in, keeping doors, graces, menus and saves working.

There’s a 0.4.2 download, released on 9 October 2026, that uses the me3 mod loader and builds Mario’s assets from the player’s US Super Mario 64 ROM. It runs offline with a separate save, and the creator lists some fairly funny problems alongside the technical ones: cutscenes can show a crumpled Mario with the Tarnished’s head, while shadows and some collisions still need work.

Minecraft in GTA V

Build a Minecraft wall in Los Santos and GTA’s traffic can collide with it, while Minecraft mobs can fight the police and a TNT blast can trigger an explosion in GTA. Rehan Remade’s project also connects arrows to bullets, fireworks to rockets and elytra flight to GTA’s camera.

Both games are running at the same time. Minecraft handles its own gameplay, while the connection lines up the cameras and draws its blocks and creatures into GTA’s view. It also creates physical obstacles in GTA where the blocks are, which lets the cars and pedestrians react to something that began in Minecraft.

That explains why this is more involved than putting Steve’s model into GTA. The two games have to agree on where things are and what happens when they meet, otherwise a wall might look solid while a car drives straight through it.

The original project targets GTA V Legacy and comes with source code and build instructions. utku67’s downloadable Enhanced adaptation credits Rehan’s work and lists its own supported GTA and Minecraft versions. Check which edition you own before choosing one, because the Legacy and Enhanced setups are different.

Spider-Man in Gotham

luki-1’s ArkWeb lets Spider-Man swing, run along walls, crawl and launch himself through Gotham from Batman: Arkham Knight. Gotham already has the buildings and atmosphere, and giving it Spider-Man’s movement is a combination we’d happily spend time experimenting with.

Spider-Man Remastered runs alongside Arkham Knight, using information about Gotham’s solid surfaces so the movement can respond to its buildings. Spider-Man is then drawn into Arkham Knight’s picture. Fights use Arkham’s combat system, with Batman’s poses transferred onto Spider-Man, so you’re getting a mix of the two games’ systems.

The creator’s demonstration is worth starting with before considering the setup. This is an experimental source project with build instructions, and it requires the documented Spider-Man version, a controller and a PC that can run both games. The creator also lists collision gaps and lighting mismatches, so the video shouldn’t be taken as a promise that every part of Gotham behaves perfectly.

Minecraft in Skyrim, skating in GTA and blocks in MW2

SkyCraft, by chasmlol, lets you place blocks, dig into Skyrim’s terrain and fight its NPCs with Minecraft weapons. Skyrim continues running its world and quests, while Minecraft supplies its own movement, inventory and building. The NPCs can fight back and interact with the blocks, which makes the idea more interesting than dropping blocky scenery into a scene.

Its 0.1.2 release is downloadable, though some scripted sections and quest interactions cause problems. The creator recommends avoiding Skyrim’s standard Helgen opening, and several Skyrim menus and abilities aren’t available while Minecraft is controlling the player.

For something different, ryglizzy’s GTA San AnSkateas gives CJ Skate 3’s movement, tricks, grinds and bails in San Andreas. Streets you already know become places to look for skating lines, which is a good reason to spend another evening in an old game. The v1.1 download needs classic PC San Andreas, rather than the Definitive Edition, and the player’s own Skate 3 files.

Then there’s chasmlol’s 2010 Rust Rewrite Mashup, which combines the original Modern Warfare 2 from 2009 with a Minecraft world and an optional skating mode. You can shoot blocks apart, collect them and build again, or get onto a board. It uses IW4L, a rewritten engine that reads assets from the player’s MW2 installation, so its approach differs from running two complete games together.

How do these mods work?

Changing a character’s appearance is usually the simplest kind of crossover: the costume changes while the original game still controls how the character moves and fights. Importing a model or map brings in more material, though showing a building on screen doesn’t automatically give it solid walls or working doors.

Gameplay also needs rules for how fast you rise and fall during a jump, how a grind follows a rail, or how a block stops something that hits it. Modders can recreate those rules, reuse existing code or connect games that already run them.

Some projects change the original game while it’s running, while others use a separate engine to load its files. The examples above take several of these approaches, which is why “they put one game inside another” is a useful description of the result without being much of an explanation.

Reverse engineering means studying how an existing program works when you don’t have its original development source code. For these mashups, that can involve finding where a game stores movement or collision information, then working out how another program can read or use it.

Where AI helps

Universal Modder, created by Rehan Remade, collects tools, instructions and shared findings for coding agents to use when working on games. Its workflow includes identifying the engine, making a small change, testing it and documenting what worked.

An agent can help explain unfamiliar code, write a connection between two systems, fix a build error or investigate why a character keeps falling through a surface. That can help someone who has an idea and is still learning the tools get further with it, though the creator still has to test the controls, check the interactions and decide whether it’s fun to play.

There’s also a lot of previous work behind the clips. ER Mario credits libsm64, the Super Mario 64 decompilation team and its Elden Ring tools, while Universal Modder credits existing loaders, research tools and game communities. Keep those names attached to the results, along with the person who made the particular mashup.

We expect more people to try making their own mashups as the tools and instructions become easier to use. If you’re interested in the coding agents themselves, our AI model ranking covers that side of things.

The appeal of doing it yourself

There’s a bit of “fuck you, we’ll make it ourselves” in this, and we like that part of gaming. A studio chooses what to sell and support; players can still have ideas that sit well outside its plans. Someone wants to skate around San Andreas, so they work out how to make it happen without waiting for an official crossover.

The “gaming has changed forever” captions are overdoing it, especially when they suggest big publishers never expected players to get this far. Counter-Strike began as a Half-Life mod in 1999, and the FiveM and RedM team joined Rockstar in 2023. These companies have had decades to see what players build around their games.

Their willingness to accept a particular project is another question. Rockstar’s current single-player support page directs modders to its terms and mod guidelines, and a fan project involving somebody else’s characters brings in another rights holder. We can enjoy the freedom behind a crossover without pretending its creators have received permission from every company involved.

An old game can get another use through a new movement system, and public code and documentation let somebody else continue the experiment. That contributes to preservation by keeping knowledge of how games work available, even when the original studio has moved on.

Final Verdict

We’re enjoying these mashups because they give us more things to do with games we already know. I want to see how Minecraft’s building changes Los Santos, how Mario handles Elden Ring’s world and what skating adds to San Andreas, even if an early version has a few things broken.

We’re on the side of people making these strange ideas playable and sharing how they did it. Follow the original creators, see what they’ve made available and try something that appeals to you, because there’s plenty here to enjoy even while the projects are still being worked on.

FAQ

Is this kind of game modding legal?

It depends on the project, the permissions involved and the law where you live. Buying both games or releasing a mod for free doesn’t settle the copyright question: the U.S. Copyright Office explains that adapting protected work generally requires permission, with fair use assessed case by case. Bypassing access protections can also raise separate legal questions. A licence for a modder’s original code doesn’t give you rights to Nintendo’s or Rockstar’s assets, so follow the publishers’ policies and avoid treating a public download as proof of authorisation.

Can using one get my account banned?

Online use can put your account at risk. Rockstar says modding in its online games can lead to account suspension, and ER Mario explicitly tells players to stay offline. Keep these experiments out of ordinary online sessions and follow each project’s instructions about launchers, anti-cheat and saves.

Can I try these on PS5, Xbox or a handheld?

The projects covered here document PC setups, and a console copy doesn’t give you an installation route for them. A handheld needs to support the required operating system and mod tools, with enough performance for the particular setup. Running two games together is a different demand from playing either one alone, so check those requirements before buying something from our gaming handheld guide.

Should I back up my save first?

Make a separate copy before experimenting, especially if you’re using a long-running save you care about. ER Mario uses its own save file, while ArkWeb’s documented setup includes backing up the Arkham Knight save. Follow the original instructions and keep your backup outside the files you’re changing, so you have something to return to if the setup goes wrong.

Do I need an AI subscription to play?

Check the individual setup, because using AI to help build a mod doesn’t mean you need an AI subscription whenever you launch it. ER Mario provides a download that uses me3, for example. ArkWeb’s guide recommends an agent-assisted setup using Claude Code through a paid Claude plan, alongside public build instructions. The requirements depend on the route you choose.
