Completion Checklist

• Clear the main objective: Meet Steven, receive the Devon Scope, clear Kecleon blockers, and mark Registeel's Ancient Tomb.
• 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.
