I tried the shareware .exe on my A1200 (with ACA 1230/56) from CLI after setting the stack to 100000 and it worked! I haven't taken any corrective action yet about the SFS error though. Odd.
It plays alright as well. I've turned off floor and ceiling and tried different detail levels and screen sizes and, after exiting the game, it reports between 8.5fps and 10fps. Only had a quick blast but clearly an impressive port.
BTW - it crashes with a Software Failure if I try to run it from the icon.
