Every week, I figure out more of the missing blocks to have Hiversaires running on #uxn.
I'm not there yet, but I found a scheme to create a single oversized rom containing all the assets of game and unpack them on load to make them usable.
For games like Oquonie or Hiversaires, which have large assets, I'd like to still distribute a single .rom file, I'm not interested in having like 10 "disks" in a zip file sort of deal.
