http://www.theatlantic.com/technology/archive/2014/07/a-quest-to-find-the-secret-origins-of-lost-video-game-levels/373925/ The author of that old Naka interview where he talks about Hidden Palace elaborates a bit on her experience with him. Apparently she gave him a copy of the ROM dump during the interview. A surprisingly in-depth article, although her referring to Naka as the 'father of Sonic' makes my eye twitch.
Oh hey, I remember her! :D I believe she posted here for a bit as well? It might have been at the GHZ or the Moogle Cavern instead, though; after nearly a decade the facts start to get a little fuzzy. In any case that's a pretty nice article!
Ah, said place has been technically gone for about that long; back in like 2007 or 2008 Kulock closed the site, but it's been limping on half-alive as another forum with a name based off of a one-off joke since then.
