The actual hardware capture looks a bit worse than it should
because I had the page flipping order a bit off but didn't catch it until I
left for the weekend.
Screenshots
Maybe at some point.
Random devel notes

The graphics didn't turn out as good as I'd hoped.
There are two images, one on lores page1 and one on page2. The waterfall
effect is done by switching pages per-scanline, but only over the water
part of the picture.
The sprite is only drawn on the background image. Erasing it takes up
over half of the VBLANK.
Ran into a frustrating cycle-counting problem when trying to use
a jump table, which turned out to be the JMP (IND) taking 6 cycles on 65c02
and 5 cycles on 6502. I ended up using PHA/RTS to do this instead.
My Mockingboard still has the frustrating glitch issue, ruining the white
noise waterfall sound effect.

Updated with my new vapor lock code and it seems to behave a lot better
with getting the waterfall to appear properly.
