Seriously, just do it. FA/F works brilliantly on it, there is no more reason to cling to that shitty shit shit 64-bit hack of a 32-bit kluge to a 16-bit clone of an 8-bit OS written for a 4-bit CPU by a two-bit company that cannot stand one bit of competition.
(I wish I could claim credit for the above but alas)
Just do it! You have no more need for Harvard Graphics anymore, you know it as well as I.
Other games? What other games?
