The bPa can't neither be captured as Pawn on a7 or b6 (Bb8 illegal), nor on c5 or c3 (with 7 wP's captures and 6 bP's captures, the wPh can't vanish). 
He has been promoted, but not before a2×Fb3, and after f2×e3×d4×c5×b6×a7 and b7-b6. The promoted piece has to be captured with d2×c3. 
a2×Bb3 occurred before b3-b4, wBb1 and b2-b3.
The moves b2-b3 and d2×c3 took place after Bb8 : this one, can't be the white Queen Bishop and come from the white promoted pawn h.
The black sequences are : f7×e6×d5 and h7×g6×h5 (all on white squares), g7×f6 (before moving the wQB : capture of the bKB with the wPf and exit of the promoted Bishop from h8 to b8). The last capture is f6×Be5.
The wBc1 has been captured on e5.

-1.Rb7×b8# ? Gives a blocked position
-1.a7×Tb8# ? Gives a black retro-pat
Last moves are : 
-1.a7×Nb8=R# Nc6-b8 -2.Qa6-c8+
Proof play :
Rh1 to f6, g7×Rf6, g7-g8=B
Bf1 to g6, h7×Bg6, h7-h8=B, bPa~, Bh8 to b8
f2×e3×d4×c5×b6×a7 (bQ+2bR+bN)
b7-b6, Bc8 to b3, a2×Bb3-b4
Ra1 to e6, f7×Re6, Bg8-f7-e8
a2-a1=N, Na1 goes out via b3
b2-b3, Bc1 to d6, c7×Bd6
wK to d8, bKb7-a8, Kd8-c8, Bb8-c7-d8, Kc8-c7
Nc6-b8, a7×Nb8=R?

wBç1 has been captured on d6
wRa1 has been captured on e6
wRh1 has been captured on f6
wBf1 has been captured on g6
