Whatever the case might be, zel said he would have sides quests included, so all legendaries would be included too, so far it doesn't matter if mew is not programmed in FR compared to Emerald, cause zel could easily create any type of event. But there would have to be time spent on thinking and putting to place on for these legendaries, like where to catch it, and what attack sets it needs, and what level? I think everybody is all of a sudden worrying about this too much and its not a major concern, because it will slow down his hack, if he has to(gameplay is important) and its far off from mind in zel... Is it necessarily to have more then one legendary in your team or is it? Tell me if I'm wrong, but prove it.
