Firstly, the reason your thread wasn't appearing is because we have a fairly strict approval process here in Emulation. The section you tried to post in was under said approval process, so that's why it wouldn't show.
Secondly, we deal with ROM hacking in Emulation. I know why you'd have thought that your thread would fit here, but I think it'd be better suited to Game Development. Having said that, I'm not sure they'd approve a thread such as yours, even if all you wanted to do was to look at maps and so on. You should probably PM the Game Development moderator, Cilerba
and see what he thinks of the situation. I myself wouldn't expect too positive a response, but it's worth asking ;)
