Nintendo 3DS

The Nintendo 3DS is similar in size and design to the Nintendo DSi, retaining the now iconic clamshell design of the DS family, along with the standard D-pad and four face buttons + two shoulder buttons on the bottom half of the console. The Start, Select and brand new Home button appear along the bottom border of the touch screen. On the top half of the console is a widescreen screen that can display stereoscopic 3D images, whose intensity can be altered using the slider control on the right side. The camera on this console is now also capable of taking 3D photos, which can be saved on removable media using the console's SD card slot. The Nintendo 3DS is backwards compatible with DS games.

CTR-001(-01)

Sometimes referred to as "Panda" units, Nintendo 3DS consoles with the code CTR-001(-01) are development consoles which are used for testing games in a standard player environment. These consoles don't offer much in terms of debugging ability and generally aren't much different from standard Nintendo 3DS consoles, only having a unique colour of the casing and special software in the NAND and BootROM. Panda units can be used to launch software from Nintendo 3DS and Nintendo DS cartridges, the NAND and the SD card, whilst bypassing the Home menu. They can't launch standard retail games or access the eShop.

CTR-001(-02)

This model is referred to as the "Partner CTR Controller" and comes with all Partner CTR devices. The Partner CTR devices are a set of Nintendo 3DS dev kits manufactured by Intelligent Systems for the purposes of testing and debugging Nintendo 3DS games. A pair of proprietary cables connect this model to the Partner CTR device, allowing both 3DS screens to be displayed on computer monitors. The ports for these cables replace where the cartridge slot would usually be on a Nintendo 3DS. The reason for the wired 3DS model is to emulate the user experience of playing a game on an actual Nintendo 3DS console, though the console is still used to control the game even if developers are choosing to use a computer monitor to view the game. In terms of hardware, this model is a reduced version of a regular Nintendo 3DS, only really containing the necessary components to power the two handheld screens, with the rest of the Nintendo 3DS hardware being contained in the Partner CTR device.

CTR-001(-04)

A retail display model used for in-store demonstrations of upcoming or recently released games, this model is largely the same as the retail model, though the system will not boot up unless connected to a WAP-002 power adapter, presumably to stop vandals from stealing them from shops.

CTR-001(-05)

Another retail display console, this model lacks the ability to use batteries, and uses a Micro-HDMI Type-D port instead of a WAP-002 port for power, though it seems to require a modified Micro-HDMI Type-D cable to function. Aside from that, the Home button doesn't work and pressing the Power button will turn the console off only momentarily, before turning the console back on again. 

CTR-001(-06)

The Louvre units are a special version of the Nintendo 3DS, which can only be found in the famous French art museum, the Louvre, intended for visitors to use as interactive guides. It does not have working speakers, though earphones can be used with the system as they are available for rental for additional charge at the Louvre. The Wi-Fi slider is either fake or glued in place. The console only has a minimal OS, basically making it useless without the CTR Guide Boot cartridge (which causes the console to launch directly into the software, and is usually screwed into the console to prevent removal by visitors). It's also speculated it may lack infrared.
