Platform: Nintendo DS
The Nintendo DS, the successor to the Game Boy Advance, is a 32-bit dual-screen (2x 256x192 pixels) handheld game console developed and released by Nintendo. The device went on sale in North America on November 21, 2004. The DS, short for "Developers' System" or "Dual Screen", introduced distinctive new features to handheld gaming: two LCD screens working in tandem (the bottom one featuring a touchscreen), a built-in microphone, and support for wireless connectivity. Both screens are encompassed within a clamshell design similar to the Game Boy Advance SP. The Nintendo DS also features the ability for multiple DS consoles to directly interact with each other over Wi-Fi within a short range without the need to connect to an existing wireless network. Alternatively, they could interact online using the now-closed Nintendo Wi-Fi Connection service. Its main competitor was Sony's PlayStation Portable as part of the seventh generation era.
As of March 31, 2016, all Nintendo DS models combined have sold 154.02 million units, making it the best selling handheld game console to date, and the second best selling video game console of all time. The success of the DS paved the way for its successor, the Nintendo 3DS, a handheld gaming console with a similar dual-screen setup. It can display images on the top screen in a three-dimensional look.
The Nintendo DS Lite is the first redesign of the Nintendo DS. While retaining the original model's basic characteristics, it features a sleeker appearance, and brighter screens. As of March 31, 2014, shipments of the DS Lite have reached 93.86 million units worldwide, according to Nintendo.
The Nintendo DSi is the second redesign of the Nintendo DS. It is based on the unreleased larger Nintendo DS Lite model. While similar to the previous DS redesign, new features include two inner and outer 0.3 megapixel digital cameras, a larger 3.25 inch display, internal and external content storage, compatibility with WPA wireless encryption, and connectivity to the Nintendo DSi Shop. Backwards compatibility with Game Boy Advance games was removed.
The Nintendo DSi XL (DSi LL in Japan) is a larger design of the Nintendo DSi, featuring larger screens with wider view angles, improved battery life, and a greater overall size than the original DSi.

Emulating the Nintendo DS
DeSmuME attempts to emulate, as faithfully as possible, the Nintendo DS and Nintendo DS Lite handheld game consoles (NDS). It currently runs on Windows, Linux, and Mac OS X. DSi is currently not supported. You can get DeSmuMe for free from the developer's site here. At Sierra Chest we've tried it out and it works very nicely.
