I have written up bits of Amber-related material here and there. You can find some of what I wrote here: http://web.archive.org/web/20050212234011/http://www.herogames.com:80/oldForum/OtherGenres/000115.html Note that that was all for fourth edition, so it's pretty out of date.
There's also a bit here, including reference to the thread above: http://web.archive.org/web/20050412064451/http://herogames.com/forums/showthread.php?t=15810
The biggest thing I can recommend is to decide whether you're running an "Amber Hero" campaign, or a "superheroes with Amberites" campaign. The latter would tend to be as generic as possible, while the former would mean you'd be essentially building an entire Fantasy Hero type "magic system" for the Amber cosmology. For example: instead of writing up, say, the Amberites' favorite Tarot cards, as a set of Powers, figure out how you want them to work in your vision of Amber, then tweak the basic game rules to follow. (For instance: contact via card might count as touch for purposes of No Range abilities, even across Shadow, and that lets you write up a whole bunch of abilities as No Range.)

(Oh hey, that's pretty neat. I had no idea the links would come up like that!)
I never saw the damage on the "damaged" copy I got, and that's been the general consensus of anyone else I've heard from. Order the book, it's worth it!
