You saw Minecraft running inside Mario 64.Now it's a launcher. Type the idea. Press Play.

Crossover is the launcher and the AI agent behind every video on my channel. Name a game you own, say what should happen. It builds the mod, installs it, starts the game and checks it actually works. Zero coding.

The agent runs on

Plus: 15 classic console games rebuilt for PC, played from your own copy.

On it. Swapping the boss model, keeping his moveset, scaling him 40x. Want him to fetch the sword?
Reply to Claude…↑

Whatever's in your head. Type it the way you'd text a friend and play it the same night.

Or don't.

give me 10 crossover ideas i could build tonight
    Ask anything↑

    No idea at all? The AI pitches ten. You pick the one that makes you laugh. It builds that one.

    The launcher

    One window.
    Every crossover.

    This is the real app, running on my PC. Mashups, rebuilt classics and your own mods in one library. Every one installs with a click and gets tested before it calls itself ready.

    Mashups. Press Play.

    Two games in one session. It sets up the second game, finds your copy, starts both. Mario 64 in Minecraft installs in about a minute.

    Classics, rebuilt for PC.

    Ocarina of Time, Majora's Mask, Mario 64, Banjo, Halo and more, running natively. You bring your own copy, the launcher does the rest.

    Not there yet? Type it.

    Game, idea, Build it. The agent opens, does the work, and the result lands in your library with a Play button.

    What happened in September

    Games used to be locked.
    Now the AI picks the lock for you.

    Last year

    • Modding meant reading machine code, hex editors and years of forum threads.
    • Moving one character between two engines took an expert months.
    • A few thousand people on Earth could pull it off.

    Now

    • The AI finds the engine and digs out the parts that matter.
    • It makes the textures, models and sounds on its own.
    • It launches the game and checks its own work.
    • You just say what you want, in normal words.

    Every comment section asks how. This is how.

    The museum of impossible crossovers

    Nine games that shouldn't exist.

    Each one was locked shut a year ago. Each one started as a single line you could type on your phone.

    How it works

    Three moves. Same three every time.

    You type the idea in the launcher. The agent finds the way into the game, builds it and tests it. Then you play, and steer it like you'd text a friend.

    It reads the engine, picks the route, writes the code, makes the assets. You watch it work.

    3Play it. Steer it.
    make the web swing faster

    It launches the game and tests itself first. Then it's yours: "bigger jump", "night mode", "add my dog".

    The vault

    The classics,
    rebuilt for PC.

    Fans took these games apart line by line and rebuilt them as real PC games: widescreen, high frame rates, mods, online co-op. The launcher installs the builds and plays them from your own copy.

    Bring your own copy. It takes care of the rest.

    Cartridge

    A USB cart reader copies your N64 or SNES cartridge to a file. The guide shows which reader and the two clicks it takes.

    Disc

    Copy the files off your Xbox or PS2 disc once. The launcher knows which files it needs and where they go.

    PC

    Diablo, Sonic Mania, RollerCoaster Tycoon: point it at your Steam or GOG install.

    It searches your PC, checks the file's fingerprint, fixes the byte order and puts it where the game expects it. No game data ever comes from us.

    What's inside

    Open the chest.

    Hover or tap any slot. The top rows are Crossover. The bottom rows are the tools it drives for you.
