Completion Checklist

  • Clear the main objective: Find Stern, beat the museum grunts, unlock the contest/battle tent side content, and leave north.
  • 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 odds are aggregated by species and method from Emerald slot rates. Most rows are marked Any time because Emerald has no normal day/night wild encounter split.
  • Pokemon table sprites use locally cached Emerald front sprites from /guides/pokemon-emerald-pokemon-sprites.json.
