Route Plan
Primary source maps covered here: Route 102. Follow this page as its own checklist, then return to the phase index when the wild Pokemon, trainers, items, and boss notes are complete.
Wild Pokemon
Each area below has its own table, split by encounter method. A species row merges every slot that species occupies for the method, and rows sort by encounter rate. Emerald has no normal day/night wild encounter split, so every row applies at any time unless its note says otherwise (for example Shoal Cave tides or Altering Cave Mystery Gift tables). Underlying slot odds: grass/cave 20/20/10/10/10/10/5/5/4/4/1/1; Surf and Rock Smash 60/30/5/4/1; Old Rod 70/30; Good Rod 60/20/20; Super Rod 40/40/15/4/1.

Source Notes
- Source of truth: pret/pokeemerald
wild_encounters.json, mapmap.jsonobject/background events, mapscripts.inc,trainers.h, andtrainer_parties.h. - Encounter rates merge every slot a species occupies within each method band from Emerald slot rates. Emerald has no normal day/night wild encounter split, so rows apply at any time unless their notes say otherwise.
- Pokemon table sprites use locally cached Emerald front sprites from
/guides/pokemon-emerald-pokemon-sprites.json.
