Prototype: incremental behavioral decompilation through a hooked DLL

Prototype incrementally reconstructs functions from the 2009 PC game's engine DLL as readable C++. A proxy xinput1_3.dll redirects calls to replacement functions; the project saves Ghidra annotations and checks replacement behavior against the original at runtime. The author reports 28 replaced functions.
