If you mean linking there, then as Annabelle said you just need to convert it.
About fixing the Age... well, except the lever that breaks when you drag it, and the lightning striking the tower, there is not much else that would worth it (except a few broken sound regions).
I forgot to say, but I've got Noloben's rain working fine (quite nice), AND Laki'Ahn's sandstorm as well. I have to say Laki'Ahn is the Age I like the least, but these sandstorms are really stunning. Unfortunately some other things are really broken (the pedestal elevator in the arena, for instance, or the Pirahna bird. We won't be chasing the poor lad anytime soon). I've done a bit of work in Tahgira but got bored. Todelmer is...... disappointing. Even after all the fixes I added to it, most of it is still broken. Direbo: well, the pedestals are a bit tricky to fix, because of SDL-instancing incompatible with PotS, and a Python script that is shared with all other four Ages. I also wanted to have a look at the Urwin, but was too lazy to do so.
Side-note: I was thinking about supplementing missing Bahros by buddies online. So you would have to solve these puzzles together. Could be fun. Offline it would still be solvable of course. Some other mechanisms, such as the Slate special powers (Environment Effect, they call it), could be half-random (rain in my Noloben falls every few minutes).
And I added a few pictures on my
Photobucket album. Nothing more than what you can see in Myst V though.
