Eight Badges, 493 Pokémon, 100 TMs and HMs, a dozen Legendary Pokémon and 964 items picked up, hidden or given: finishing Diamond, Pearl or Platinum at 100% takes planning. Here is the complete checklist, with tick boxes that your browser remembers from one visit to the next.
Items follow the order of the adventure: each location shows the walkthrough step where you reach it. Version-exclusive items carry a label; items with no label exist in all three versions.
Tick items off as you go: each location's counter updates, and a completed location is shown with a check mark. Your ticks are saved in your browser, on this device.
