How to read these tables

Morning is 4:00–9:59, day 10:00–19:59 and night 20:00–3:59 on the game clock; a table marked "any time" is the same all day. Swarms, Hoenn/Sinnoh Sound encounters, and special night-fishing replacements are not active in this hack and are excluded. "—" means the table stores no level or chance for that entry. The encounter rate is how often you meet wild Pokémon on that map (higher means more often).

These are the ordinary encounter tables. Calendar encounters can replace specific land slots. Visible spawns and capture-chain bonuses use additional rules; table weights are not shiny odds.
