r/Disney_Infinity

Disney Infinity 3.0 has local split-screen co-op on consoles, but it shipped disabled on the PC port. I've been reverse-engineering the game and got it working again as a small, reversible mod. 🎉

⚠️ This is an early release (v1). It works, but it still has rough edges (see "Known issues" below). I'm sharing it now so people can try it and send feedback — bug reports, crashes, and "it worked great in X world" are all super helpful. 🙏

What it does

• Restores local 2-player split-screen co-op on PC — in the Toy Box AND in Play Sets (story worlds).
• Player 2 joins by pressing START on a second controller. Split screen, each player on their own gamepad.
• Player 2 can change character on the fly: RB = next, LB = previous (controller 2).
• It only offers characters valid for the current world (e.g. in the Inside Out Play Set you only cycle the Inside Out cast). It auto-detects every character loaded and auto-fixes Player 2 if they join a Play Set with a character that doesn't belong there.

How to use it

1. Copy the files into your game folder (where DisneyInfinity3.exe is).
2. With the game closed, run INSTALL.bat.
3. Launch via Steam, load a world, plug in controller 2, press START on it.
4. To remove it, run UNINSTALL.bat (or verify files on Steam).

How it works (for the curious)
It's a proxy bink2w32.dll: it forwards all the game's Bink video calls to the original DLL, and in the background it calls the game's own drop-in function + installs tiny in-memory hooks to set up the second player and split screen. Character validation uses the game's own in-engine Lua VM (it hooks lua_pcall to ask the game Player_IsCharacterValid for the current world). It doesn't modify the .exe and doesn't touch saves, online or achievements — fully reversible.

Known issues (v1) — help me test these!

• Occasional crash when Player 2 joins. The "spawn" step is a bit flaky right now. If it crashes on join, just relaunch and press START again — it usually works on the next try.
• After P2 changes character, Player 1 may briefly look like a hologram/ghost — P2 just taps START once to refresh P1.
• Re-joining P2 after leaving to a different world doesn't work yet in the same session — restart the game to re-join.
• If a character model ever shows up "white/untextured", cycle to another one with RB/LB.

I'm actively working on these for v1.1, so detailed reports (which world, what you did, did it crash on join or later) are gold.

(Heads up: the Nexus file may be pending its automatic malware review for a bit — normal for mods with a compiled DLL — so use the GitHub link meanwhile.)

Huge thanks to LucasLhomme (a.k.a. crabe_crabe) — his CrabeLoader and DisneyInfinity-SplitScreenMods projects made the Player 2 "join" (controller + viewport + split) and the Lua API mapping possible. This mod builds on his work with his permission:

• https://github.com/LucasLhomme/CrabeLoader

Requirements: Disney Infinity 3.0: Gold Edition (Steam) + 2 Xbox-style (XInput) controllers. Thanks for testing, and let me know how it goes! 🙌

Early build — works in Toy Box and Play Sets. You'll see Player 2 join, the per-world character picker (RB/LB), and the current rough edges (P1 hologram → tap START to refresh; occasional crash on join → relaunch). Feedback welcome! Links in the post.

My thing is to bring this back it’s also gotta make sense to DISNEY. since they decided it would be a good idea to sell all their IPs to Fortnite. Fortnite is literally gonna die at some point that game does not have a good life span compared to Roblox. The game needs to be live service with a new subscription yearly/monthly for toy box exclusive content and a brand new Disney Hub A COMPLETE DIGITAL OVERHAUL. Where you can make your Toy box Avatar. Invite your friends create custom games like “Paintball,” but your avatar has to available only to launch toybox games. Toybox exclusive story mode and outside content will revolve around the big IPs. Like “Star Wars, marvel and Disney originals,” see but they are missing all their own profit by letting somebody else make their money? Like you can sell characters costumes and accessories all on your own and MAKE WAY more money to use to make better Disney content for your own fans. I want to go into a Disney Hub and play Disney original songs again that I grew up with and listen to “Jessie,” intro theme or watch an episode with my friends as my avatar! Those specific wonderland niches aren’t even being made anymore when they could have easily switched to digital INSTEAD. And just sold figures on the side….Disney lacks trust in itself honestly. I miss Disney infinity so bad I wish the game team would just try to hear us out.

Is the game still fun as an adult?
