Einhander - native Windows port (static recompilation)

The game is NOT included. First run only: put your own disc image (Einhander.chd,
or the .cue file and its .bin; North American release SCUS-94243) next to
einhander.exe or in the "game" folder, then run einhander.exe.
(Or drag the disc image onto einhander.exe.)

The disc is imported once into assets.dat and verified to be an exact copy.
After that the game runs from assets.dat alone - delete the disc image.
The install is then just:
  einhander.exe, SDL2.dll, assets.dat (+ memcard1.mcd, einhander.ini)

F1 or Esc (Start+Select on a controller) opens the settings menu, including
Keyboard keys and Controller buttons for rebinding. Hold Tab to fast-forward.
Saves go to memcard1.mcd next to the exe (a standard PS1 memory card image,
usable in emulators). Settings are in einhander.ini.
