Def Jam: Fight for NY — statically recompiling the Xbox game

This statically recompiles Def Jam: Fight for NY for the original Xbox, USA version, to Windows. The installer checks the ISO and refuses the European disc. DJFFNY.exe is the single-window installer. A hand install uses Installer.bat. The MSVC package is about 2 MB and can use DLSS on an NVIDIA RTX card. The built-in Clang package is about 100 MB. The install needs about 4 GB free and an XInput controller.
