I've compiled it, and there are forks of it updated to compile w/ the latest CTRULIB. Buggy as hell tho. If someone wants the latest compiled they can have it, although it really isn't hard to compile. Just download CTRULIB from the same date of the last commit.
I found how to make it work on wine. Download the latest source, open a terminal, and CD to /resources/NTRViewer. Then run "wine NTRViewer.exe <Your IP>"
I felt like white text made it looks too bright. I really like how the black on black looks, because I personally can easily read it even on the lowest brightness setting.

Alas I have updated the post with a white text theme.
Actually a theme this time
To install, take PhoenixDarkTheme.zip and extract the "fbi" folder inside to the root of your 3ds' SD card. (would still like a dark 3d banner)
That's it!

EDIT: Here's a fully white version with white icons as well.
