Helpmate-programs - and some problems for you....

There must be some good programs for solving/composing helpmates today.
But where?
In 1995 I made a silly dos-program named Brutalis.
It had some nice options, though.

With the help of Brutalis I made most of the problems below:
1) A game ended with 6.gxf8N mate.
2) A game ended with whites move 9.Nd6+ mate. How is that possible,
when white has only moved a knight and black has only moved a pawn?
3) A game started 1.f3,f6 2.g4,Nc6 3.d4 and ended in move six, where the white king was mated on h4.
4) White mated black in a game, where both black and white only moved a single knight.
5) In a game that involved a capture, whites king on f4 was mated in 4 moves.
6) In a game that involved 2 bishop-moves, whites king on g4 was mated in 4 moves.
7) A game ended with whites move 8.Nd6++ mate with a doublecheck.
How is that possible, when white has only moved 2 pieces, black has only moved a
pawn, the ending position has a knight on b1 and
a) the white queen is on e2?
b) the white queen is on a4?
8) A game ended in five moves with knight captures pawn on h2 with
mate. 4 solutions each with a different placement of the black queen.
Origin: from the danish Skakbladet 1988, that many
readers and I discovered had several solutions. It was a pity for the problem,
but with a new presentation of the problem, I have turned a faulty problem into
four new tasks. The author is C.D.Locock, and the problem was
published in Fairy Chess Review august 1946.
9) A game ended with knight captures pawn on g2 with mate. How is
that possible, if
a) black has done four moves?
b) black has done five moves and the ending position has a rook on h1 and
1) whites bishops have not moved?
2) whites bishop from f1 is on another square on the kingside?
3) whites bishop from f1 is on the queenside?
c) black has done six moves and the ending position has a bishop on f1 and
1) black has moved 3 pieces on the kingside?
2) white has done 4 pawnmoves on the kingside?
3) white has done 6 moves with a knight?
4) whites king is on the second row?
5) white has done 5 moves with a bishop?
6) white played 1.Nc3 and 6.Ne4?
d) black has done all nine moves with a knight and white has only moved a
pawn?
e) black has done all ten moves with a knight and white has only moved the
d-pawn?
