FAQ

Are AI merge games real or fake?

Many are real. The MW2, Skate 3 and Minecraft mashup, SkyCraft and Mario in Elden Ring all have public code and downloads on GitHub. Some viral clips, including the original Minecraft in Elden Ring video, have never been released. Every entry on this site is labelled Playable, Build it yourself or Video only.

Do I need to own both games?

Almost always, yes. Legitimate mashup mods never include game files. They read the files from your own installed copies, the same way Garry’s Mod needed other Source games back in 2004. Each mashup page lists exactly which games, versions and platforms you need.

Is it safe to download AI game mashups?

Only from the creator’s own repository. Fake look-alike repositories appeared within days of the trend. We link the official page for every project and never re-upload anything. Back up your saves before installing, and never run an unsigned .exe from an account created the same week.

Can I get banned for playing these mods?

Not if you stay offline. Most mashups only run with anti-cheat switched off, and the creators are explicit that they must never be taken online. Games such as Elden Ring and GTA V can ban accounts that join online play with modified files.

Do AI merge games work on Mac?

Most are Windows only, because the host games are Windows PC games. The Minecraft Crossover Bridge is the exception: it runs Minecraft inside Elden Ring or Monster Hunter World on Apple Silicon Macs through CrossOver. Use the finder and pick Mac.

Can I merge two games myself with AI?

Yes, if you are patient. Tools like Claude Code with the open-source universal-modder toolkit can identify a game’s engine, decompile it and build a mod. You still need to own the games and to judge what feels right. The AI cannot. Read the step-by-step guide.

Are AI game mashups legal?

It is a grey area. Reverse engineering for compatibility is allowed in some places, but distributing a publisher’s files or characters is not, and publishers can demand takedowns. Fans who rebuilt GTA 3 and Vice City were hit with a DMCA takedown in 2021. That is why every project here asks you to bring your own games.

I made a mashup. Can you list it?

Yes. Send us the official repository or video link. We read the README, check what you need to own, and add it with the right status label. We never list projects that bundle game files.Email us

Playable · Engine transplant

Mario in Elden Ring (ER Mario)

Play Elden Ring as Mario with Super Mario 64's real movement and moves.

Official download

★ 152 · updated Oct 6, 2026 · v0.4.0

Links to the creator's own GitHub page, checked Oct 7, 2026. We never host or re-upload files, and no game files are included. Re-uploads and look-alike repos can carry malware.

ER Mario swaps the Tarnished for Mario. Triple jumps, wall kicks, long jumps and ground pounds all work on Elden Ring’s terrain, punches hurt enemies, and you can grab a staggered boss by the tail and swing it like Bowser.

How it works

The mod loads a small Rust DLL into Elden Ring through the me3 mod loader. Inside it runs libsm64, a library built from the community’s Super Mario 64 decompilation, fed with Elden Ring’s live collision. The Tarnished stays in the game invisibly and follows Mario, so doors, Sites of Grace, menus and saves keep working. That is an engine transplant: one game’s movement engine running inside another.

What changes

Your stats stop mattering. Every punch takes a fixed share of an enemy’s health, Mario always has SM64’s eight-wedge health meter, and stamina and equip load are ignored. It is a different way to play, not a power mod.

What you need

  • Elden Ring on Steam.
  • Your own Super Mario 64 ROM (US version). Mario’s textures, sounds and animations are generated from it on your PC.
  • The me3 mod loader.

Install in short

  1. Install me3.
  2. Download the ER-Mario zip from the official GitHub releases and unzip it somewhere writable, such as Documents.
  3. Put your ROM in the ER-Mario folder and double-click er-mario.me3.
  4. On first launch the mod sets itself up from the ROM; when it says Setup complete, restart the game the same way. Start a new character, because the mod uses its own save.

Stay offline

me3 launches the game offline with Easy Anti-Cheat off. The creator is explicit: never play this mod online. Streamers need window or display capture for the HUD to show.

Known issues

You can occasionally clip through elevators, cutscenes show a crumpled Mario with the Tarnished’s head, and Mario’s shadow can flicker in some light. The mod is still a work in progress and updates often.
