I am all in favour of great projects, but why a differentiation between 32-bits or 64-bits? I don't understand that. Is a computer that is 32 bit or 64 bit, either way which, not worthy?
Edit: I understand a motivation if it is on simplicity choosing one or the other, but other than that I don't see why that should ever be a goal worthy to be pursued. Software should really "just work" no matter the number of bits and bytes.
It only won't work on modern pure-UEFI systems because that would require writing full stack of USB drivers for keyboard and mouse, and that would be a huge task.

Not really how software works.
Just sold my SGI Indigo 2 for 900 $ ! Vintage 64 bit is absolutely a thing. :-)
Personally I’d have said it isn’t. But these terms are subjective.
(That distinction wasn't clear to me either, so I had to look it up - TIL).
Just type the word “retro” into YouTube (for example) and you’ll see thousands of videos from hundreds of channels spanning decades talking about old games and computers.
The last step (32-bit to 64-bit) can a bit of a can of worms especially on older platforms where 64-bit implementations can differ greatly and 32-bit "just works tm". 32-bit is quite well supported and has enough resources to make some interesting programs work without much hassle.
I think the author has made the decision not to support 64-bit mode due to needing to balance the complexity and usability of the project. It is a hobby project after all.
Since the author maintains a 16-bit and 32-bit for this project I suppose if you wanted you can always fork and maintain a 64-bit version if you wanted to.
