Dear Maintainer,

1. The keybinding information seems to be outdated and reverses 3 bindings:

       Keyboard can be configured and by default works as follows:
              F1-F10 load savegame from slot 1-10
              Shift+F1-F10 save game to slot 1-10
              Non-keypad arrows act as d-pad
              z = A
              x = B
              ...
              Left Shift = SELECT

x/z have been flipped, as has left/right shift. That is: x = A, z = B, select = Shift_R.

2. The man page also omits the option `--depth-threshold`; passing an option like `--depth-threshold=10` is necessary to get some games like _Advance Wars: Dual Strike_ into a playable state (eg, you can't see the cursor in _Dual Strike_ without that option; #452 https://sourceforge.net/p/desmume/bugs/452/ ).
