Just a quick post to say that the 10 or so testers that kindly gave up their time to put Apple Jack through it's IBM compatible paces have done an excellent job, and left me with a long list of things to do before I can finally release it.
The first attempt was a bit of a non-starter, since it failed to install properly on all but one computer.
The second version ran properly for the most part but generated the aforementioned list of shame, which I shall work through over the coming weeks.
No more testing is needed now. Thanks to everyone who helped out or offered help once I already had enough helpers; names will be added to the credits menu before release and I'll send the finished games to you once I know better where they are going to end up.
