About
UnNetHack is a fork of NetHack, a single-player roguelike video game in development since 1987.
It features more randomness, more levels, more challenges and more fun than vanilla NetHack, trying to be the game NetHack would be if it were still in development.
There is a project page on sourceforge and a public server at un.nethack.nu.
For discussion, join the IRC channel #unnethack on irc.freenode.net or post to rec.games.roguelike.nethack.
The current released version of UnNetHack can be downloaded here. The development code is available from the subversion repository.
NetHack-De is a German translation of NetHack.
Its project page is on sourceforge and the current version can be downloaded here.
UnNetHack & NetHack-De 
I hope you are actually still keeping up with this…
If you are, I’d really love it if you could tell me how to change the options to default untiles instead of the tty graphics. I’ve been trying for a while now, and I just can’t see how to do it.
Thanks!
I guess you are talking about the Windows version. You need to have a line like
OPTIONS=tile_file:unchozo32b.bmp,tile_width:32,tile_height:32
in your defaults.nh.
Then it should load and display the tiles by default.
Aaah, sorry, should have mentioned I’m using a Mac.
Oh, there is no tiles version for the mac yet.
