As I said before somewhere around here, I started the effort to make maped
Mono compilant.
After a days of work, I got it to open, and edit the map on linux.
This screenshot was taken on Ubuntu 7.10, with maped running on Mono 1.2.3:
I still have to (sadly) strip off corona form it, clean a lot of code (maped codebase is messy as hell), and iron out a good bunch of bugs.
EDIT: I don't have a Mac, so I can't test compatibility for OS X, I'd appreciate if someone could help with that :)
