Pokémon HeartGold & SoulSilver Battle Arcade — Dahlia Walkthrough
Control the roulette and defeat Dahlia at 21 and 49. Exact HGSS encounters, trainers, items, puzzle route, version differences, and completion checks.
Control the roulette and defeat Dahlia at 21 and 49. This combined guide never substitutes original Gold/Silver or Crystal data for the Nintendo DS remakes.
Source maps
Battle Frontier Battle Arcade.
Version scope
HeartGold and SoulSilver are labeled per row. Event-only and external-device content is never presented as normal retail progression.
Route Plan
Practice timing the board cursor, prefer effects that aid your side or hinder theirs, build to survive unavoidable weather and status, and prepare for Dahlia's fixed Silver- and Gold-Print rosters.
Wild Pokémon
No random encounter bank is assigned to these source maps. Static, gift, Safari, Contest, or event records appear separately when applicable.
Trainers
Teams are the exact source party records. Moves and held items appear only when the trainer format defines them. Reward = last party member level × 4 × trainer-class multiplier; double battles double the base payout where the engine applies it.
| Trainer | Location / order | Full team | Reward | Battle note |

Items And Hidden Items

Puzzles And Systems
Follow the route plan in order; source tiles in the item and trainer tables provide a QA anchor for every placed object.
