Route Plan

Primary source maps covered here: Route 105, Island Cave. 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.

Completion Checklist

  • Clear the main objective: Start the Surf route south of Petalburg/Dewford and mark the Regice cave for the later Regi quest.
  • Review every wild Pokemon method listed for the section.
  • Fight or deliberately skip every trainer listed in route order.
  • Collect visible items, hidden items, and scripted rewards you care about before moving on.

Source Notes

  • Source of truth: pret/pokeemerald wild_encounters.json, map map.json object/background events, map scripts.inc, trainers.h, and trainer_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.
