I was wondering how to manually create your own Wonder Mail (aka what are the algorithms for creating it). I've found out about upokecenter's Wonder Mail Generator, but that doesn't interest me. I've een gone so far to contact nintendo, and they responded with this email:
Thanks for contacting us. As our resident PokéManiac, I can certainly understand your interest in the Wonder Mail feature of Pokémon Mystery Dungeon: Blue Rescue Team. While answer your question, Nintendo does not provide game play assistance, so we do not have the information you are looking for.
It may interest you to know that Prima Publishing has produced game guides for many of the titles we’ve published. You can find a complete list of available guides at their website (http://www.primagames.com).
I wish you the best of luck in playing this game!
