Black captured wBc1 with an officer on c1 and exdxcxb; White captured fxg and g5xh6, so there are three white captures left to explain. wBg3 is wPa2 promoted on b8 following axb and b6xa7xb8=B, because this pawn is the only one that could not have been captured by bPe7, so last move was not a7-a6. bPe7 captured lightsquared wBf1 on its way to b3, so last move was not b4-b3. The other seemingly possible last moves by Black are easily ruled out, so White made the last move, and it is Black who mates in two.
Solution:
1... Kxe8+ 2. Sf6 Dxf6#, not 1. Sdf6+? Ke7 2. Rxd7.
