Pokemon Diamond and Pearl Route 208, Hearthome City, and Amity Square Walkthrough

Collect the Berry Searcher, reach Hearthome, unlock Poffins and Contests, explore Amity Square, and trigger Barry's second battle on departure. This standalone section joins the route plan to the original Diamond/Pearl map, encounter, trainer, item, and script data; Platinum tables are not substituted.

Route Plan

Clear Route 208's first-visit paths and visit the Berry Master's house; mark Fisherman Cody for Surf and Hiker Alexander for Rock Climb; rescue Buneary at Hearthome's entrance; visit the Contest Hall; receive the Poffin Case; tour Amity Square; prepare at the southeast gate; defeat Barry before Route 209.

• Fantina refuses a Gym challenge in Diamond and Pearl until four badges have been earned; Platinum's earlier Gym order must not be imported.
• Bebe's Lv. 5 Eevee gift requires the National Dex in original Diamond/Pearl. Platinum makes it available on the first Hearthome visit; that earlier timing does not apply here.
• Amity Square permits only its approved 'cute' species and hides accessories/items at warp points behind scenery.
• Route 208 is a multi-visit trainer map: Fisherman Cody waits across Surf-only water, and Hiker Alexander stands on a Rock Climb-only upper ledge.

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.

Route 208

Route 208, Hearthome City, and Amity Square

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.

Items

Hidden Items

Puzzles, Warps, And Switches

1. Amity Square's stone huts teleport between fixed points. Enter each hut from both sides and check behind structures with the Dowsing Machine to complete its item loop.
2. Barry approaches when the player uses Hearthome's southeast exit; heal before crossing the gate threshold.

Boss Strategy And Partners

Completion Checklist

• Complete the currently reachable part of this route plan: Clear Route 208's first-visit paths and visit the Berry Master's house; mark Fisherman Cody for Surf and Hiker Alexander for Rock Climb; rescue Buneary at Hearthome's entrance; visit the Contest Hall; receive the Poffin Case; tour Amity Square; prepare at the southeast gate; defeat Barry before Route 209.
• Review all 19 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/pokediamond at commit 038cccaed5de8f013875bc5d734f912d1de08e0f: 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.
