A curated selection of retro Game Boy Advance and Nintendo DS titles available on the Nintendo Switch eShop. While Nintendo Switch Online boasts a substantial Game Boy Advance library, this list focuses on titles independently released on the eShop. Ten games are highlighted – four Game Boy Advance and six Nintendo DS – presented without ranking.
Game Boy Advance
Steel Empire (2004) – Over Horizon X Steel Empire ($14.99)

Kicking things off is the shoot 'em up, Steel Empire. Although the Genesis/Mega Drive version holds a slight edge, this GBA iteration offers a compelling, streamlined experience. A worthwhile addition to any collection, especially for comparing versions, and surprisingly accessible even to non-shooter fans.
Mega Man Zero – Mega Man Zero/ZX Legacy Collection ($29.99)

While the Mega Man X console series saw a decline, the Mega Man Zero series on GBA emerged as a worthy successor. This inaugural entry, while exhibiting some initial rough edges, lays the foundation for an excellent side-scrolling action series.
Mega Man Battle Network – Mega Man Battle Network Legacy Collection ($59.99)

A second Mega Man entry, justified by its distinct gameplay from Mega Man Zero. This RPG features a unique battle system blending action and strategy within a clever virtual world concept. While later installments show diminishing returns, the original remains highly enjoyable.
Castlevania: Aria of Sorrow – Castlevania Advance Collection ($19.99)

From the Castlevania Advance Collection, Aria of Sorrow stands out as a personal favorite, even surpassing Symphony of the Night for some. Its soul-collecting system encourages replayability, complemented by engaging gameplay and a unique setting.
Nintendo DS
Shantae: Risky’s Revenge – Director’s Cut ($9.99)

Originally a cult classic with limited distribution, Shantae: Risky’s Revenge on DSiWare catapulted Shantae to mainstream success. This title, bridging the gap between a cancelled GBA game and later installments, solidified Shantae's place in gaming history.
Phoenix Wright: Ace Attorney – Phoenix Wright: Ace Attorney Trilogy ($29.99)

Arguably a GBA title by origin, Ace Attorney blends investigation and courtroom drama with humorous storytelling. The first game sets a high bar, though later entries also hold merit.
Ghost Trick: Phantom Detective ($29.99)

From the creator of Ace Attorney, Ghost Trick offers a unique gameplay mechanic: manipulating objects as a ghost to save others while uncovering your own past. A captivating and highly recommended experience.
The World Ends With You: Final Remix ($49.99)

Considered a top-tier Nintendo DS title, The World Ends With You shines best on its original hardware. However, the Switch version provides a viable alternative for those without access to a DS, offering a compelling and well-crafted experience.
Castlevania: Dawn of Sorrow – Castlevania Dominus Collection ($24.99)

Part of the Castlevania Dominus Collection, Dawn of Sorrow benefits from improved button controls over its original touch-based controls. However, all three DS Castlevania games within the collection are recommended.
Etrian Odyssey III HD – Etrian Odyssey Origins Collection ($79.99)

While the Etrian Odyssey series thrives on DS/3DS hardware, this Switch port offers a playable experience. Etrian Odyssey III, the largest of the three, provides a substantial RPG adventure.
