Nintendo DSi vs. Original DS: All Differences Explained

The Nintendo DSi (2008) was a significant mid-generation refresh of the DS line. Here's every meaningful difference from the original DS (2004) and DS Lite (2006).

Hardware Improvements

Feature	DS / DS Lite	DSi
Cameras	None	Two 0.3 MP (VGA): inner + outer
Screens	3.12" (256×192)	3.25" (256×192) — slightly larger, brighter
Storage	Game cart only	256 MB internal NAND + SD card slot (SDHC up to 32 GB)
Audio	Mono speaker	Stereo speakers (improved quality/volume)
CPU/RAM	ARM9 @ 67 MHz + ARM7 @ 33 MHz / 4 MB RAM	ARM9 @ 133 MHz + ARM7 @ 33 MHz / 16 MB RAM
Battery Life	15–19 hrs (DS Lite)	9–14 hrs (brighter screens, more power)
Weight	218 g (DS Lite)	214 g (slightly lighter)
GBA Slot	Yes (Slot-2)	Removed — no GBA backward compatibility

Software & Features

DSi Shop: Digital store for DSiWare (games, apps, clocks, calculators). Closed 2017; content redownloadable until 2023.
DSi Browser: Opera-based web browser (slow, limited HTML5).
DSi Sound: Music player with voice recording, pitch/speed effects.
DSi Camera: Photo app with lenses, frames, face detection.
System Menu: Redesigned with icon-based layout, SD management, parental controls.
Region Locking: DSi-enhanced/DSi-only cartridges are region-locked (original DS games remain region-free).

DSi XL (2009) Additional Notes

4.2" screens (93% larger), better viewing angles, two stylus sizes, longer battery (13–17 hrs). Same internals as DSi.

What You Lose vs. DS Lite

GBA cartridge slot (no Pokémon migration, no GBA games, no Guitar Hero: On Tour grip).
Longer battery life.

Verdict: DSi is better for DSiWare, cameras, media, and speed. DS Lite is better for GBA games, battery life, and flashcart homebrew. For most today, a 3DS/2DS supersedes both (plays DS + 3DS + DSiWare + GBA via VC/injection).
