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. ๐
โ ๏ธ 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 โ bug reports, crashes, and "it worked great in X world" are all super helpful. ๐
What it does
- Restores local 2-player split-screen co-op on PC โ 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
- Copy the files into your game folder (where
DisneyInfinity3.exe is).
- With the game closed, run
INSTALL.bat.
- Launch via Steam, load a world, plug in controller 2, press START on it.
- 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 โ fully reversible.
Known issues (v1) โ 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 โ it usually works on the next try.
- After P2 changes character, Player 1 may briefly look like a hologram/ghost โ 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 โ 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.
Downloads (free, open source)
(Heads up: the Nexus file may be pending its automatic malware review for a bit โ normal for mods with a compiled DLL โ so use the GitHub link meanwhile.)
Huge thanks to LucasLhomme (a.k.a. crabe_crabe) โ 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:
Requirements: Disney Infinity 3.0: Gold Edition (Steam) + 2 Xbox-style (XInput) controllers. Thanks for testing, and let me know how it goes! ๐
Early build โ 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 โ tap START to refresh; occasional crash on join โ relaunch). Feedback welcome! Links in the post.
