ROM Maker - Updated?

Hi All,

I'm looking for a windows utility, that can edit, customize and update an existing rom...

Basically, I am trying to tweak a Chinese rom to make it more INTERNATIONAL... However I'm not seeing many Windows (GUI) Apps that can do this, and if there is, they've been discontinued at ICS or earliest JB build.

Does anyone know an updated tool that can help me with this please...??

PhilzTouch is supposed to support this, but the package didn't work either...

Thanks, Lister
