I work on it every once in a while, but, until I have it at beta or at least a semi-playable status, I'm waiting before I make a revival thread. I may even just wait for the 649 patch to finish and re-do what I've done, or copy what isn't in that patch. I mapped and fit in most of the events just past the first Gym. All the leaders were already in the game, but, yeah, you get what I mean.
I'm also thinking about doing a Ruby 2 and Sapphire 2 in the vain of B2/W2, it'd probably be 10 years after R/S, Hoenn changes a bit geographically (Less Sea and some new towns/cities, etc.) 'cause of the fight between Groudon and Kyogre, a Land and Sea Forme for Rayquaza. New trainers, Red-like roles for Brendan/May. It'd probably be made on FireRed so it'd require actual work to make, haha.
