Honestly, I'm not completely satisfied with the aforementioned backgrounds. They are passable, and probably as good as I can do right now, but they aren't perfect. I could spend months trying to make them "perfect", but I don't think I'd get there. Even if I managed to rip the models, it would be extremely difficult to get the lighting and rendering just right. It's not like Peardian's maps where the models are presented by themselves and can be rendered however he pleases, but rather they are right next to pixel-perfect graphics and need to be rendered exactly.
And speaking of headers, I'm kind of torn over how to credit everyone who helped out. On the one hand, this started as an Atlas project with several contributors, but on the other hand, I did all but 9 rooms by myself (I redid all of Edsword's maps, as well as a few others for consistency). I think I will say something on the lines of "Mapped by Revned, thanks to TerraEsperZ, Mephea, Zeric, Wileee and Edsword". Does this sound okay?
And Jon, I know you want it, but it's really not just a matter of flipping the map. The game renders the top and bottom unevenly, such that I would be missing a row of pixels if I did that. And since this game uses so many colors, palette-swapping isn't even trivial. If I end up doing it (no time soon), it will be mostly from scratch.
