The full story
In Disney Infinity 1.0 (2013), each character figure is locked to its home playset, so Mr. Incredible can only play in the Incredibles world. Modders had tried to lift the restriction for over a decade without success.
The block turned out not to be a single flag: one function, FindPlaysetForCharacter, is called at 13 points across six parts of the game's C++ code, so patching one check leaves the other twelve in place. Data-only mods failed because native code validates first, and DLL injection crashed the game. Working on the binary with no symbols or source, Claude Code (Opus) helped trace the call graph, find all 13 call sites, read the conditional jumps after each one and work out the exact bytes to patch, through several failed attempts.
The patch lets characters play outside their home playsets, and the post drew a large response from the game's modding community.
