Henrik Juel: White captured Sb5xQc7 and Be8xRf7. Black captured a7xPb6, c6xRd5, d7xRc6, e7xBd6, h7xPg6, Qc7xSc8, and Rf8xSf7 five times. (2003-10-14)
James Malcom: What is the full solution? (2023-05-30)
Henrik Juel: The retroplay is something like
R: 1. ... Sh7-f8+ 2. Le8xTf7 Tf8xSf7 3. Se5-f7 Tf7-f8+ 4. Sc4-e5 Tf8xSf7 5. Sh6-f7 Tf7-f8+ 6. Sa3-c4 Tf8xSf7 7. Sg5-f7 Tf7-f8+ 8. Sb5-a3 Tf8xSf7 9. Se5-f7 Tf7-f8+ 10. Sc7-b5 Tf8xSf7 11.

Earlier in the game Black captured a7xPb6, c6xTd5, d7xTc6, e7xLd6, h7xPg6, and White promoted on a8, c8, d8, h8.
The full retroplay back to the initial array can be constructed from this information; it has been done in a solution comment to Goldsteen's wonderful P0002345, which has no Pf2 in the diagram position (2023-05-30)

It is impossible to let Sb8 just switch-back, so it performs a square round-trip
