Hello, there.
I'm a little late to the party, I only got around to trying the KotC demo yesterday. So, it seems I missed the font hating from the early versions.
The current fonts are readable, certainly, and they have some of that old-school character.
But I do prefer my text to be really, really readable. Sans-serif readable. So, I checked out the modability of the demo. Sure enough, the graphic resources are all in windows bitmap or dds format. Thanks, programmer.
So, I took a few hours to redraw my custom Dwarf Fortress font in the two sizes needed for full-screen (640x480) KotC play.
And here they are, in case anyone else cares to use them:
To use, right-click the images, save them locally, and then open in Paint or something and resave as 60.bmp and 62.bmp, in 24-bit color bitmap format.
Then, rename to 60.dat and 62.dat, and replace the ones in the Graphics subdirectory of the KotC program directory (after backing up the originals, of course).
