Gratuitous Fairy Conditions against duals :-)
Game starting position. h#2, Koeko
Since White technically has the move, either mate White or start with Black.
Only 1.f6 e3 2.g5 Dh5# remains :-)

That's really funny!
For a second I thought Monochrome would work too, but alas a single dual remains.

?? Bh4 isn't mate, g5 defends against the check (assuming you meant 'g4' where you wrote 'g5')

@Jacques: 👍 Lulz were had, alas, I doubt this condition replaces Chess960
in OTB tournaments soon - since apparently Popeye doesn't have it :-)

This is a great find. I would have been happy to take for The Problemist.

A few "near misses":
PAS, AlphabeticChess, HaanerChess, ser-#12
1.a2-a4 2.a4-a5 3.a5-a6 4.a6*b7 5.Sb1-c3 6.b2-b4 7.b4-b5 8.b5-b6 9.b6*c7 10.b7*c8=Q 11.Sc3-e4 12.c7*d8=Q #
You can add "no underpromotions" (two R work) but still 11.Sc3-d5 is the same.
PAS, Volage, BlackMaximummer, ser-h#11
1.Sb8-c6=w 2.Sg8-h6=w 3.a7-a5 4.Ra8-a6 5.Ra6*c6 6.Rc6*h6=w 7.c7-c5 8.Qd8-b6 9.Qb6*h6 10.Qh6-a6=w 11.b7-b5 Qa6*c8 #
The first two moves may be swapped.
PAS, EinsteinChess, WhiteMaximummer, h#4
1.e7-e5 Sg1-h3=P 2.Bf8-a3=S Sb1*a3=B 3.c7-c5 Ba3*c5=R 4.Qd8-e7=R Rc5*c8=Q #
1...Sf3=P is the same.
PAS, AlphabeticChess, EinsteinChess, ser-#17
1.a2-a4 2.Ra1-a2=B 3.Ba2-e6=S 4.a4-a5 5.a5-a6 6.a6*b7=S 7.Sb1-c3=P 8.b2-b4 9.b4-b5 10.b5-b6 11.b6*a7=S 12.Sa7-c6=P 13.Sb7*d8=B 14.Bc1-a3=S 15.Sa3-b5=P 16.b5-b6 17.b6*c7=S #
12. Sa7-c8=B also works. Bummer.
Possibly in one of the next SCHWALBE I've got a hit, though (and the fairy "clerk" added a twin even more hair-raising :-)
