A retenir :
- nom de code : CAT-DEV (Cafe Tool for Development)
- les dev kit sont "fait-mains"

As we promised we launch this new section with a big surprise for everybody. We have exclusive pictures of Wii U‘s first development kits.
The codename for these devkits (and their next iterations) is CAT-DEV (Cafe Tool for Development) plus the version.

The first thing you will notice is the devkit’s size. It’s trully very small, also looking as if it’s custom made, not “mass produced” equipment.

As you can see from the pictures below these kits don’t have support for the DRC (Display Remote Controller) yet. They only have support for the Wii Classic Controller with a special port (which we will see in our next article). So it’s interesting to notice that at the very first stages of Wii U’s life developers weren’t using the new controller at all.

Other thing you can notice about it is the lack of optical media. Only the newest devkits have support for the propietary media that Wii U uses.

In the back you will see the same outputs as in a Wii console plus the HDMI output and the classic controller port.

In short, we can see that the Wii U first devkits are a strange piece of hardware.
