I might fore-go compatibility in favour of a plain ST hard drive version... The fact that the game is slightly buggy anyway can't help. I suppose the ULS version done for 1mb machines will cover anything I haven't done... although... I'm just toying with a High-Score saving routine starting at roughly $7bc?? (For the Boiler Room addicts) but a vector isn't the bst place to do this imho :-/
