When I try to install the English-Chinese dictionary using TiLP (http://www.omnimaga.org/index.php?topic=10595.0) on my TI-Nspire CX CAS (patched with cx2cxc http://www.omnimaga.org/index.php?topic=14137\), TiLP does not do anything. It does not even output a terminal message. This is probably because ZiDian.tcc does not contain the header of a normal OS upgrade file.
Support for these dictionaries was added and tested by the end of the next day, it's part of the libraries associated to the TILP II 1.17 and now 1.18 releases.
