Does Nintendo DS Lite Need Wi-Fi for Multiplayer? No—Local Wireless Works Offline

No. The DS Lite uses DS Download Play (local ad-hoc wireless) for multiplayer—zero internet, zero router required.

• Two DS Lites within ~30 ft connect directly.
• Host loads game → "Multiplayer" → "Download Play".
• Guest: DS Menu → "Download Play" → selects host's game.
• Host sends minimal data (few MB) to guest's RAM; guest plays without cartridge.

Exception: Some titles (e.g., Mario Kart DS, Pokémon Diamond/Pearl) offer *optional* Nintendo Wi-Fi Connection (WFC) modes for internet play—WFC shut down 2014. Local wireless remains fully functional offline.
