Fallout-NV-MacOS: static recompilation of Fallout: New Vegas for Apple Silicon

Fallout-NV-MacOS translates the 32-bit Windows executable of Fallout: New Vegas through Ghidra P-code into C for native Apple Silicon builds. A host supplies Win32 and COM shims plus Direct3D 9-to-Metal rendering, while a differential tester compares translated functions with the original x86 instructions in Unicorn. The author reports an hour of scripted play; audio, Bink video, and gamepad support remain unfinished.
