It just so happened that I logged on here for the first time in nearly a year, and you only left your comment a few days ago! Yes, please use Alfa and Ohmega! I'd love to see them in a game. I don't suppose there is any way to make it so that when they breed, they produce Unown? There's gotta be something in Manaphy's coding that could allow it to do that.
I finished the map and posted it! I posted the map file instead of the rom, since you said that you wanted that.
I put a lot of effort into the post. I hope you like the map, I worked hard on it, but even if you don't please tell me so I can fix it!!
