I just wanted to know if you know a solution... I've been editing Black version for my emulator so there will be Pokemon from Gen I-IV on the trainer's rosters as well as in the wild. I found and bookmarked a webpage that gave me all Pokemon and Trainer data for the Battle Subway. I've been finding ways so I can modify the Battle Subway by adding the Pokemon used in the Gen IV Battle Frontier. So do you have any solutions or ideas that can help me find a way to modify it? If not, then I sincerely apologize for wasting your time.
