  • Morning: 04:00-09:59. Day: 10:00-19:59. Night: 20:00-03:59.
  • Grass slots total 100%; time, swarm, Radar, GBA insertion, Marsh, and Trophy Garden systems replace designated slots rather than adding extra probability.

  • Honey uses four save-specific eligible Munchlax trees. Great Marsh rolls one 32-entry daily index per area. Trophy Garden retains today's and yesterday's report.
  • CompoundEyes changes held-item checks. In the Great Marsh Safari Game, catch and inspect Pokémon because Thief and Covet cannot be used.
  • Static, gift, trade, fossil, roamer, Pal Park, event, and Frontier access rows are labeled separately from ordinary wild encounters.

All 105 Platinum trainer classes have an 80×80 web asset and manifest entry. Regular tables use small class sprites; boss cards scale the same source frame.

Source And Validation

  • Source checkout: pret/pokeplatinum at commit 7c0aa10b6a6aa09d8824e08bd8a36f6fc8b7ad8d.
  • Tables draw from res/field/encounters, res/field/events, res/field/scripts, res/trainers, held-item data, map headers, hidden items, berry initialization, trades, tutors, and Frontier sets.
  • Trainer order follows event objects, then source scripts. Held items and moves appear only when Platinum defines them; rewards use highest party level × 4 × the trainer-class multiplier.
  • Extracted 8,480 raw encounter rows, 502 placed trainer battles, 329 item balls, 242 hidden items, 118 initialized berry patches, 38 shard tutor moves, and all five Frontier Brains.
  • Machine-readable validation report records the final invariants and coverage totals.
