The TI-Nspire OS does support optional add-ins.
Together with its TI-Nspire softwares 3.1, TI had included english-chinese dictionnary add-ins for the TI-Nspire OS.
The add-in files look similar with OS files:

Unfortunately, it was impossible to install the dictionnary on our TI-Nspire CX.
You needed to own the chinese model: the TI-Nspire CX-C.

And knowing that CX and CX-C models were sharing the same OS, there was some verification somewhere...
Fortunately, Levak has developped some code this evening which has been included in a new tool, cx2cxc, and hot-patches your TI-Nspire CX OS, making it believe that your handheld is a TI-Nspire CX-C! ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)

No restriction! Unlike a real TI-Nspire CX-C, you can still choose between 15 languages instead of 4. ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)

But like a real TI-Nspire CX-C, the dictionnary shortcut is now active and available in the home screen, and you can install the english-chinese dictionnary! ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)
