FAudio.dll & XAudio2_8.dll -> I built a win64 release build of FAudio, an XAudio reimplementation, licensed under zlib.
SDL2.dll -> A win64 release build of SDL2, licensed under zlib.
XInput1_4.dll -> The original DirectInput XInput1_3.dll file from Microsoft, but renamed to XInput1_4.dll. ( Cube World Beta 0.9.1-0 only uses the XInputGetState export so this works.)
