How does one go about designing and using a graphical tileset for
NetHack?

Uh, thanks. Okay:

Where is a list of the game elements?
What image format needs to be used?
How do the tiles get imported into the game?

Based on the errors I found rife in at least one
tileset, by all means figure out how to do the
drawing of each tile as a separate image, not to
draw all the tiles on one huge image; too many
tile-edge-trespasses happen that way. Piecing the
tiles together will be tedious, afterwards, though,
and some software to help would be nice.

Also an issue, if you are trying to build tiles with
a minimal set of colors, like the original NetHack
ones that work with the ASCII-to-image-format conversion
loop, is that you can accidentally add extra colors with
each tile, unless you choose your palette of colors first,
once and for all. Stuff like scaling images smaller, can,
at first paradoxically seeming, add more colors too, as
blends of the existing colors.

So, to repeat, two good strategies are to somehow avoid
drawing across tile boundaries, and to somehow limit the
size of the color space, which lets (indexed-mode) tiles
be stored in smaller files.
