So essentially I'll post this to skew anyone ask in future messages. Metapod will most likely update this and has not gone dead on it. As most people know, we all get busy, so he randomly appears like Ho-oh, dropping new updates. The fact is, some updates take longer. So whether it's 1 or 2 years, just be patient. He's one of few ROM creators that actually follow through with their work. And this game has been extensive.
Hopefully that helps. Meta keep it up. Eagerly and patiently awaiting the completion.
