Source Notes
- Source of truth: pret/pokeemerald
wild_encounters.json, mapmap.jsonobject/background events, mapscripts.inc,trainers.h, andtrainer_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. - Frontier Brain streaks and teams come from
src/frontier_util.c; Factory rental behavior comes fromsrc/battle_factory.c; facility mon sets come fromsrc/data/battle_frontier/battle_frontier_mons.h. - Trainer art on this page uses the local Emerald trainer manifest and reused Hoenn character art where Emerald-specific artwork is not available.
