Source maps

Version discipline
Rows merge only when Diamond and Pearl are identical, and each row carries D/P game markers. Version-exclusive species, mascot encounters, swarms, Radar slots, and GBA insertion slots keep their own labeled rows.
Route Plan
Save before interacting; lead with sleep or paralysis; weaken without relying on recoil or residual knockout damage; throw Dusk Balls at night/in cave-qualified conditions only where applicable and Timer Balls in long fights; catch the mascot; collect its version orb behind the platform; speak to Rowan downstairs.
- Dialga and Palkia are version-exclusive in ordinary play. The other mascot requires trading or another compatible distribution/game path.
- If the mascot is defeated instead of caught, it reappears after entering the Hall of Fame again. Saving beforehand is still the fastest way to retry immediately.

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, and GBA dual-slot 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
Field order follows the map's object-event order. Full teams include explicit held items and moves when trdata defines them; cash rewards use the in-engine final-party-slot level and trainer-class multiplier formula.
No trainer object, scripted battle, or assigned boss team is sourced for this section.
Items
No visible item ball, decoded scripted gift, or curated system reward is assigned to this section.
Hidden Items
No type-2 hidden-item event is present in the source maps assigned to this section.
Puzzles, Warps, And Switches
- The Adamant Orb or Lustrous Orb sits beyond the legendary's starting position. Walk to the far edge and collect it before leaving Spear Pillar.
Boss Strategy And Partners
No Gym Leader, rival branch, Galactic boss, Elite Four member, Champion, story partner, or major postgame battle is assigned here.
Completion Checklist
- Complete the currently reachable part of this route plan: Save before interacting; lead with sleep or paralysis; weaken without relying on recoil or residual knockout damage; throw Dusk Balls at night/in cave-qualified conditions only where applicable and Timer Balls in long fights; catch the mascot; collect its version orb behind the platform; speak to Rowan downstairs.
- Review all 2 encounter rows across the per-area tables, including game markers, method band, time-of-day rates, levels, and each conditional requirement; mark conditional rows for their stated revisit.
- Defeat or deliberately skip every currently reachable trainer row; leave HM-, story-, or National-Dex-gated rows checked only after their access requirement is met.
- Collect currently reachable visible/scripted items and berry trees, use the Dowsing Machine for reachable hidden rows, and retain every explicitly gated row for the named cleanup visit.
- Resolve every currently available puzzle note, boss branch, and partner scene before opening the next section.
Sources And Validation
pret/pokediamondat commit038cccaed5de8f013875bc5d734f912d1de08e0f:map_header.c, D/P encounter archives,trdata.json, zone events, script archives, item tables, and trainer graphics.- Encounter slots were decoded from exact 424-byte D/P members and cross-checked against Gen IV slot behavior; the 0x6C pair is day, morning uses base slots, and 0x74 is night.
- Coordinates remain visible as QA anchors, while each hidden row also provides a plain-English map-region instruction.
- Generation-wide systems that are not tied to a normal map archive—Honey Trees, Great Marsh daily rolls, Trophy Garden, fossils, Pal Park, and event items—are explicitly curated in their dedicated system pages.
