Thanks for the info, I'll be sure to get a real thorough understanding of Kolf 
before attempting the port, and will be ready to do a significant amount of 
work. Kolf as it stands has quite a few bugs (eg balls going through walls 
and ending up on top of each other and then behaving strangely in 
multi-player), so it could probably do with quite a bit of work.
