I have updated the Shogi presets to spot check, checkmate, and stalemate,
and they can now also enforce the rule against checkmating the King with a
Pawn drop. They can also now use aliases for promoted pieces that each
equal the label for its unpromoted state with a + sign in front.
To see the code behind this, check out one of the presets, such as this
one:

and the include file used for all Shogi presets:
