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.
