Their original image was 64K. They cut it down to 34K (+ 512 bytes) and then they included it in their binary (rather than loading from a file).
So it seems that David was correct in his explanation. They could only display about half of a 320x2X0 image because they ran out of low memory.
But it also seems that VERA doesn't have enough video memory to hold a 640x480 8bpp bitmapped image ("Mode 7"). 128K of private video memory just isn't enough unless they start playing tricks.

I really am curious to find out if they plan on adding more memory or if this is going to be one of those quirks we'd have to really work to take advantage of? :)
Based on what I see here, you've got a good explanation: https://github.com/FrankBuss/x16-demo/tree/master/assembly
