Which platform first received Kingdom Hearts 358/2 Days?

Kingdom Hearts 358/2 Days first appeared on the Nintendo DS.

Square Enix developed the game specifically for Nintendo’s dual-screen handheld, making it the first Kingdom Hearts title designed for the platform. The DS was selected before development began, and the hardware influenced the game’s mission-based structure, touch-screen features, and control scheme.

The story follows Roxas during his time in Organization XIII, fitting between the original Kingdom Hearts and Kingdom Hearts II. It also introduces Xion and expands the background of Axel and Roxas. Although the game was later included in anniversary packages and its story was adapted into a cinematic compilation, those releases did not change its original platform.

A common mix-up is confusing 358/2 Days with Kingdom Hearts: Chain of Memories, which debuted on Game Boy Advance, or with Dream Drop Distance, which was made for Nintendo 3DS.
