NDEV

NDEV 2.1

The NDEV (product code RVT-001) is the main development system for the Wii, taking the form of a large black box including full Wii hardware with 128MB of RAM as well as debugger and Host I/O hardware.

The NDEV features all the ports and functionality found on a retail system, in addition to additional communication ports for debugging and host communication; it does not have a disc drive, and all software is read from the host system.

Difference between 1.x versions is unknown. 2.01 (ES) is also unknown, it is mentioned as 2.01 ES in one SDK document.

Between 1.x and 2.0:

• Changes in NDEV text size

• Addition of IOS (with crypto support)

• Likely addition of a boot program (with visible output to the TV)

• (Unlikely, rumor/speculation) Removal of second SD card slot

• Addition of wireless functionality

Versions:

• 1.0

• 1.1

• 1.2

• 2.0

• 2.01 (ES)

Between 2.0 and 2.1, the number of wired Wiimote ports went from 4 to 1. This is the main way to identify a 2.0 (rare) from a 2.1 (very common).
