Thanks DPainter!
Does seem to work on a real Amiga (I was able to boot into the game and start playing, on my accelerated A1200)
I used Warp 1.11 from Aminet (
ftp://de.aminet.net/pub/aminet/util/arc/warp-1.11.lzh)
(You require 2 disks. I used the commands:
for the first disk:
unwarp BDARK1A.WRP BDARK1B.WRP df0:
second disk:
unwarp 100BDARK2.WRP df0: )
