Not having much luck doing the WHDLoad install either.
Disk1 comes up as DF0:Uninitialized so the WHDload installer wont pick it up.
Tried booting with the image on DF0 (setting my HDD as a higher priority so it doesn't boot from the Disk) same results.
Will try on a real Amiga after writing the ADF back to Floppy.
The Game works fine booted from the ADF though with standard A1200 config in WinUAE and is very fun
