Is Nintendo DS Lite the Only Console That Plays Game Boy Advance Games? No—Several Systems Do

No. Multiple Nintendo systems play Game Boy Advance cartridges natively via Slot-2 (GBA cartridge slot).

Systems That Play GBA Cartridges

Original Nintendo DS ("Phat," 2004): Slot-2 (bottom) plays GBA natively. Larger, dimmer screens.
Nintendo DS Lite (2006): Same Slot-2, smaller, brighter screens, better battery. Best all-around for GBA.
Game Boy Advance SP (AGS-001 Frontlit / AGS-101 Backlit): Native hardware. AGS-101 (backlit) is the gold standard for GBA play.
Game Boy Micro (2005): Tiny, bright screen, no GBA link port. Collector favorite.
Original Game Boy Advance (2001): Horizontal, no light (frontlit mod exists), reflective screen.
Game Boy Player (GameCube Accessory, 2003): Plays GBA/GBC/GB carts on TV via GameCube. Requires startup disc. Best big-screen GBA.

Nintendo DSi / DSi XL (2009/2010): No Slot-2. Only DSiWare (downloadable) — zero official GBA titles released.
Nintendo 3DS / 2DS / New 3DS (2011+): No GBA slot. Ambassador Program gave 10 GBA games via Virtual Console (3DS only), but no cartridge support.
Wii / Wii U / Switch: No native GBA support. Wii U Virtual Console had ~10 GBA titles. Switch NSO has none.

For Cartridge Play + Modern Feel: DS Lite (AGS-101 equivalent screens, GBA slot, compact). ~$50-90 used.
For Pure GBA Experience: Game Boy Advance SP AGS-101 (backlit). ~$80-150. Best screen, native ergonomics.
For TV Play: Game Boy Player + GameCube + component cable. ~$100-150 total.

DS Lite or original DS are the best modern-feeling options with GBA slot. For pure GBA, AGS-101 SP is ideal.
