Wild Pokémon
Each area below has its own table, split by encounter method. Standard grass and cave rates merge every base slot for a species and are shown per time window: morning 04:00-09:59, day 10:00-19:59, night 20:00-03:59. Swarm, Poké Radar, GBA dual-slot, and Trophy Garden replacements keep their own labeled rows. Underlying slot odds: grass 20/20/10/10/10/10/5/5/4/4/1/1; Surf and Old Rod 60/30/5/4/1; Good and Super Rod 40/40/15/4/1.

Trainers
Route order follows event-object order, then source-script order. Teams show held items and moves only where Platinum explicitly defines them. Rewards use the engine formula: highest party level × 4 × trainer-class multiplier.
