I dunno if its the config or not but running on a mister FPGA with the amigavision config (= A1200 minimig preconfigured) the .adf wont work, it gives something like "no dos device" in floppy when reset and says N0DOs under the icon when inserted, also on a500 setting it just gives a flashing grey screen.
The .lha works fine when extracted, great game too.
just fyi
