Hardware
The Nintendo DS is powered by two processors, an ARM7 at 33MHz and an ARM9 at 66MHz. Each of the screens has a 256x192 resolution, and can disaplay approximately 260,000 colors. The system has 4MB of main memory, with an additional 665KB of video memory.

While the system is backwards compatible with the Game Boy Advance, it does not include the further backwards compatability that the GBA provided to Game Boy and Game Boy Color games. This is due to the fact that the DS does not contain the Z80 processor that the GBA used for GB/GBC emulation as well as GameCube connectivity and wired Game Boy connectivity for multiplayer games. These features are therefore not included with the DS.

The DS game cartridges are much smaller than GBA cartridges, with a stated maximum size exceeding 1 gigabit (128MByte). Games are packaged in cases that look like half-height DVD cases, with a snug pocket for the DS cartridge and another for a GBA cartridges.

In addition to the two cartridge slots, the DS has a power adapter port, a headphone port, and a port for an external microphone, as well as the built-in mic. Input methods include the D-Pad, four face buttons, two shoulder buttons, and the touchscreen. A mini stylus (and one spare) is included with the system and slides into a slot on the back of the console.

The system can connect wirelessly with other devices in two ways. DS-to-DS connectivity uses Nintendo's proprietary wireless protocol for short range connections. Many games have what is called "download play" where only one cartridge is required for several players within DS-to-DS range. Additionally, with the introduction of Mario Kart DS and Animal Crossing: Wild World the Nintendo Wi-Fi system has been launched. Using these games (and others in the future) players can connect to many 802.11b access points and play with other users worldwide. For those who do not have a compatible Wi-Fi access point, Nintendo sells a USB device that will allow any Windows computer with an internet connection to provide wireless connectivity.
