I created a patched version of the new 9.410 Navcore with switchable emulations from the menu - use the skin chooser on the last page.
It is an Asian Navcore, therefor you get added support for the Asian keyboard and the Asian iFlyteck TTS engine.
As I don't have a device to test it on you download and install at your own risk.
Make a full backup using Windows Explorer,
check your backup,
delete all ...
