*Inventions from Generations IV and V were hinted in the third generation games, Ruby, Sapphire and Emerald. If you go to the Devon Corporation building, on the second floor you see various scientist working on computers. When you talk to the scientists, one states that he is working on a device that will revive Pokémon fossils he follows by stating its working. When you talk to the other scientist on the computer he states that he is working on a device that will visually reproduce the dreams of Pokémon and he follows by stating that it is not going well. If you talk to the last scientist on a computer he will say he is developing a device that will allow you to talk with Pokémon he follows by saying that he hasn't had much success.
*In Platinum, Fantina is the third Gym Leader. Maylene is fourth and Crasher Wake comes fifth.
*When the franchise first moved its games during this generation, Junichi Masuda wanted players to use their fingers, but the other devs thought that was dirty and wanted them to use the stylus. The argument went on for months.
