Case study

openNG2: a static recompilation of Ninja Gaiden II for Windows

openNG2 turns the Xbox 360 Ninja Gaiden II into a native Windows build through ReXGlue static recompilation and game-specific host code. Its launcher builds from a user-owned World release and Title Update #2; the research ledger records evidence from REA, Ghidra and code generation while the port adds PC display and input features.
