I'd just like to say that AncientRuby, from the few screenshots i've seen, looks fantastic. I normally would offer help and such, but don't know much about GBC hacking, and you've pretty much got everything covered, from the looks of things. So in conclusion, well done on such a brilliant idea.
PS, i gave your page it's 3000th visit, w00t!
(Do i get a prize or something?). Lol.
