I played this at the Atari party in the US this weekend, and it was great! People loved it. I'm looking forward to running it on my own hardware!
A couple of extra observations:
I had trouble getting the .st image onto a floppy, which is 99% likely to be me working my greaseweazle incorrectly. But I dropped the .st file onto a USB drive, hooked up a gotek in the STE on my bench, and copied the files onto hard drive. Then hooked up a real floppy drive to go in the opposite direction: put the files on a floppy.
Upshot: the game actually runs great from the hard drive anyway! credits.prg bombs out from HD -- I figure because it's looking to call right into the game program which is in the wrong place -- but the game itself runs a-okay for me.
This machine also has an exxos 32MHz booster in it. Good news, the game runs fine under acceleration. One thing that I can't quite put my finger on is that the audio maybe glitches a little in this mode, but I don't have a side-by-side recording of that vs. the audio with the CPU clocked at 8MHz to convince myself. It does make me aware that there are probably some fixes I could make to this machine to improve the audio: in general, I get a few clicks and whistles that I don't want.
Otherwise, I tested exclusively on TOS 2.06, UK-english version on a 4MB STE.
If I were to want one feature, I think it would be a toggle for the chip music. The engine noises are a little low in the mix for me, and I kind of want to hear those good engine noises over the chip music!
Incredible work all round. Really happy to see this out.
Oh also: I realise the Falcon isn't a target, but it almost works. Attached a couple of photos.
Glitchy pixels! Including a strip along the horizon. And the tinny internal speaker didn't do anybody any favours, so I'm not sure how faithful the audio was. Those things aside, it booted and played smoothly so the core mechanics are good!
