Phase 1 Coal Badge Twinleaf Town, Lake Verity, Sandgem, Jubilife, Oreburgh Gate, Oreburgh City, and Roark. 01 / 11 
Receive HM06 Rock Smash, cross the entrance floor, and mark the basement's Bicycle, Surf, and late-HM obstacles for cleanup. This standalone section joins the route plan to the original Diamond/Pearl map, encounter, trainer, item, and script data; Platinum tables are not substituted.
Source maps
Oreburgh Gate 1F and Oreburgh Gate B1F.
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
Talk to the Hiker for HM06; defeat both mandatory trainers; collect reachable items; continue east to Oreburgh; return after the Coal Badge to use Rock Smash and revisit again with the Bicycle and Surf.
- Receiving Rock Smash is not enough: the Coal Badge is required before the field move works.
- The basement deliberately contains rewards gated by multiple later abilities; the page should label each item by its earliest access point.

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.

Hidden Items
No type-2 hidden-item event is present in the source maps assigned to this section.
Puzzles, Warps, And Switches
- On the first visit, ignore blocked rocks and the bicycle slope. After Roark, smash the nearest rocks for the first basement pocket without treating the whole basement as complete.
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: Talk to the Hiker for HM06; defeat both mandatory trainers; collect reachable items; continue east to Oreburgh; return after the Coal Badge to use Rock Smash and revisit again with the Bicycle and Surf.
- Review all 14 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.
