Hey butfluffy,
I can't find the .IPFs either...
There is a working set of .ADFs though:
{CRC 076C95A5} Fantastic Voyage (1991)(Centaur)(Disk 1 of 3)[cr SKR][t +4 Ache - Extensors].adf
{CRC 035A3FAD} Fantastic Voyage (1991)(Centaur)(Disk 2 of 3)[cr SKR].adf
{CRC 03B75B15} Fantastic Voyage (1991)(Centaur)(Disk 3 of 3)[cr SKR].adf
Only have one drive enabled, after the ship is shrunk a screen with wavy horizontal coloured lines will appear, insert Disk 3, load for a few seconds and you will be prompted to insert Disk 2
