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
Leave Route 226 north; clear every ash-grass trainer; visit the rest house; use the Bicycle across narrow rails; climb with Rock Climb; collect items around crater ledges; meet Buck; enter Stark Mountain fully stocked.
- Route 227's ash is environmental only in Diamond and Pearl; do not add Hoenn soot-collection mechanics.
- The rest house provides free healing and is the safest staging point for the long paired section inside Stark Mountain.

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.

Puzzles, Warps, And Switches
- Align carefully before each narrow Bicycle beam; dropping sends the player to a lower loop. Finish each Rock Climb side ledge before approaching the cave mouth.
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: Leave Route 226 north; clear every ash-grass trainer; visit the rest house; use the Bicycle across narrow rails; climb with Rock Climb; collect items around crater ledges; meet Buck; enter Stark Mountain fully stocked.
- Review all 34 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.
