Since the Nintendo DS is a retro console, you will need an emulator to run the game file.

If you are ready to adopt this specific niche of retro entertainment, here is a sample lifestyle integration guide.

Morning (7:00 AM - 8:00 AM): Play the 4780 HeartGold download on your phone using an emulator (like Delta or RetroArch) during your morning coffee. Walk your Pokémon through Route 32.

Lunch Break (12:30 PM - 1:00 PM): Battle the Goldenrod Gym. This 15-minute challenge is the perfect mental reset from spreadsheets.

Evening Wind-Down (9:00 PM - 10:00 PM): Connect your game to a large monitor via HDMI. Grind the Elite Four while listening to a lo-fi hip-hop stream. The combination of the nostalgic visuals and modern soundscapes creates a unique entertainment bubble.

Modern entertainment is often multi-channel. You watch Netflix while scrolling Twitter. The 4780 HeartGold download excels here because turn-based combat requires only peripheral attention. You can grind levels while listening to podcasts, audiobooks, or attending Zoom meetings that could have been emails. It fills the "mental idle time" in your day without requiring the focus of a cinematic PS5 title.
