For Patzer v3.61 this is easy:

00:00:00  d->01   -5.51  Rc8
00:00:00  d->01  +3.21  Rh8+
00:00:00  d->02  +3.21  Rh8+ Kg4
00:00:00  d->03  +2.81  Rh8+ Kg4
00:00:00  d->03   -0.26  Rb1 cxb1=Q Bxb1
00:00:00  d->04   -0.28  Rb1 cxb1=Q Bxb1 g4
00:00:00  d->05   -0.34  Rb1 Bh3+ Kg1
00:00:00  d->06   -0.82  Rb1 cxb1=Q
00:00:00  d->06   -4.57  Rb1 cxb1=Q Bxb1 e3
00:00:00  d->06   -2.53  Rh8+ Kg4 h3+ Kf4 Rf8 c1=Q Be6 Ke5
00:00:00  d->07   -2.53  Rh8+ Kg4 h3+ Kf4 Rf8 c1=Q Be6 Ke5 Bxf5
00:00:00  d->08   -2.60  Rh8+ Kg4 h3+ Kf4 Rf8 c1=Q Be6 Ke5 Bxf5 Qd2
00:00:01  d->09   -2.57  Rh8+ Kg4 Rf8 c1=Q
00:00:01  d->10   -2.57  Rh8+ Kg4 Rf8 c1=Q h3+ Kf4
00:00:01  d->10   -2.10  Rb1
00:00:03  d->11   -0.12  Rb1 cxb1=Q Bxb1 e3 Bxf5 e2 f3 e1=Q Bg4 Qc3
00:00:03  d->12   -0.37  Rb1 cxb1=Q Bxb1 e3 Bxf5 e2 Bg4 e1=Q h3 Qd2 Kf3 Qd3+ Kg2
00:00:05  d->13   -0.40  Rb1 cxb1=Q Bxb1 e3 Bxf5 e2 Bg4 e1=R h3
00:00:06  d->14   -0.42  Rb1 cxb1=Q Bxb1 e3 Bxf5 e2 Bg4 e1=Q h3
00:00:12  d->15   -0.40  Rb1 cxb1=Q Bxb1 e3 Bxf5 e2 Bg4 e1=Q h3 Qc1 Kf3 Qf1 Ke3
Qe1+ Kf3

Cool - for such things, Patzer is always worth a try, Roland puts some really
