There’s a new @Play column focusing on more of the entries at the Seven Day RogueLike competition. I mention this because roguelikes have been around on Unix-ish systems forever, some of these may work on DragonFly, and because they are much more complex and interesting than I would have thought possible.
A running description of activity related to DragonFly BSD.
I started getting the first one of part 1 working on dfly. After 3 hours I gave up.
SFML needs to be ported to dfly: http://www.sfml-dev.org/
In particular it seems to need joystick support which is based on Linux which appears to be very different on dfly.
Doryen relies on SFML and may need to be ported as well: http://thedoryenlibrary.appspot.com/
I didn’t even start on this library.
