U can't pack back to vis file as far as I know, at least if u don't have paid version of Visionaire Studio Editor 5.
So to make translation u need to have a .ved file (can take it
here or
there) and my compressed version.
With Visionaire Studio Editor 5 (free edition) u can still be able to make/add a new font with chinese letters (but not sure if it even supported for that language) and also export text to csv and po (could be useful for auto-translation) or u may edit ved file directly with Notepad++ or similar tool.
P.S. Futher questions ask in translation thread not here or in PM and better ppl who made translation for this game, not me.
