Hey, thank you for the start. I'm currently in the Battle Tower battling her team and trying to learn the attacks everything has.
________Starting the Battle Tower________
Okay, this took just around 5 or so minutes, this was surprisingly cooperative:
The Walrein has Rock Smash, Body Slam, Waterfall, and Aurora Beam.
THUNDER (Pikachu) has Shock Wave, Thunder Bolt, Thunder, and Dig.
Tropius has Stomp, Sweet Scent, Growth, and Razor Leaf.
I vaguely remember the team she would have had. I don't know if these were on her team, but I do know that she had a high-level Mudkip that she never evolved, a Groudon that I think had Solar Beam, and she might have just captured Latios (I think that was one of the last things she did before the game was lost forever) but I might not remember that properly. I want to say that she traded me a Golduck and/or Dodrio, but I traded them to her Diamond in ~2011ish and she may have restarted her save without realizing they were in there. If possible, the Mudkip is the most important one of the Pokémon that don't show up in the Battle Tower. I'm not sure if her whole team exists or just the trimmed down 3-Pokémon team for the Tower, but that's one that I'm hoping for.
I'm going to try to use Hall of Fame Extractor to see if I have any of those in the Hall of Fame with a Trainer ID that isn't mine. There are up to 50 total Hall of Fame entries that are recorded in Gen 3, so I'm going through each slot.
________Checking all 50 slots________
In the application, the Golduck in the Hall of Fame has an ID of 30171 and Secret ID of 28575, Level 44. I'm not positive that this is from her save file but it's the only Golduck with an ID that doesn't appear anywhere. If you're using Hall of Fame Extractor it will appear as Entry #27. In game, it will appear as HALL OF FAME No. 44. Again, I'm not sure if that ID is hers but it's probably the best clue I have.
If there's anything else I can possibly provide, I will gladly share more.
