Pokémon DS Games on iPhone: Not Natively Possible

Original DS cartridges cannot play on iPhone.

Why

• Hardware: iPhone (ARM iOS) vs DS (dual ARM9/7, custom GPU).
• Media: No cartridge slot.
• OS: No official Nintendo emulator on iOS.

Legal Alternatives

• Pokémon on iOS Officially: Pokémon GO, Masters EX, Sleep, TCG Live, Quest, Café ReMix, UNITE.
• Remakes/Ports: None for DS mainline (Gen 4/5)—only Gen 1 (Red/Blue/Yellow via VC on 3DS, not iOS).
• Cloud Streaming: Xbox Cloud Gaming (Game Pass)—no Pokémon.

Emulation (Legal Gray Area)

• Delta / iNDS / NDS4iOS: Sideload via AltStore (no jailbreak).
• Requires: Self-dumped BIOS + ROMs from owned carts.
• Performance: Good on A12+ chips; touchscreen controls imperfect.

Best Legal Path

Play Gen 4/5 on original DS/3DS, or wait for potential Switch remakes (rumored).
