Lamentable but understandable.
Support for a device that's gone the way of the Dodo as far as 99% of the users out there are concerned isn't a high point on their list of things to keep alive. Only the smaller subset of users that care about the game itself (& ones like it) might care about a FD compatible code, but how many of those have a FD to use in the first place?
*Shakes head sadly*
It's like lamenting that we no longer use punch cards, MFM HDD's, or Beta video cassette tapes. Or horse buggies, or chipped stone axes, or... or... or Big Ben's roof as a spot from which to moon the French!
*Cough*
I'll get my coat, it's the one with my ASCII in the pocket...
