Thanks for trying. If you fancy such things, you might give a try to Loriciel's Space Racer IPF's (the French version seems at stake too, playing it doesn't require any skill in that language). There's a working ADF of that game (labeled cr [cbc]), so the situation is not as bad as ISS's.
As an aside, Amigans with deep pockets should buy more originals, so that we peons may obtain tried IPF's for the games we don't own an original of
