Hello, I've managed to port clonekeen over to OpenBSD. clonekeen is a clone of the classic Commander Keen game (http://en.wikipedia.org/wiki/Commander_Keen). It requires the original data files to play though. I've tested on i1386 with both the shareware and full version and it seems to work nicely although it core dumps when you exit which I haven't had a chance to look into yet...
Please let me know if there's any feedback. Thanks!
