Sixteen Badges, 251 Pokémon, 57 TMs and HMs, 26 Unown, six legendaries and more than 450 items found or received: completing Gold, Silver and Crystal 100% takes organization. Here is the complete checklist, with checkboxes that your browser remembers from one visit to the next.

The list follows the map: Johto first, then Kanto. For each location, every visible, hidden or gifted item is listed with its exact location and, where relevant, the version concerned.

Tick items off as you go: each location’s counter updates, and a completed location is shown in gold.
