Now the position is almost legal.

also seems possible a black bishop on f4 and to withdraw the pawn f3

Yes, thanks for all the testing by Olaf! ichai is right with bPh7 and the bBd4 can be replaced by a bP. The last proposal with bBf4 loses one move at the end with 106.Kg2-h1 Kc1-d1 107.Bg3-g2 Kd1-e1 108.g2-g1S Ke1-f1 109.Sg1xe2 Bd3xe2 110.Lf4-h2 Le2-f3#

Here is again the current record but I would wait a bit before announcing that as final. There are still some ideas how to add moves that I would like to explore ...

Could the simple move of the black bishops on a7 and b8 to g1 and h2 in James' 97-mover add 20 moves to the solution? Then we would have 118 moves with the additional move to g8 of the bK and adding wPh7 and wRh8...

Okay, I see …
Here is another try to add moves. If I count right, the bK needs at least 3 moves more to reach f8 after the capture of the wBh5, maybe even more... Then at the end it could be one move shorter with bKh1 bBh2 wKf1 and Bf3#

Jacque’s try is probably cooked as the bK can capture the wBf1 directly after the wBd1 (with wKh2 wBh1) and then the wPh3.

The 113-mover also does not work as the wK can capture bishops in the North=East and then the bPg3.

It seems possible to add two moves :

put the white king on f1
add a white bishop on h1

it is not evident, but it does not shorten the main maneuver, because bishops g1 and h2 must be removed before the black king takes on d1 to avoid a pat.
And, at the end you must play Ke1-f1-g1xh1xg2 instead of Ke1-f1xg2
