The Chinese version does all of the same things the English version does, it's just got the menus in Chinese. You cannot use the English loader on a Chinese G6, but it wouldn't be hard to figure out how to use it with the Chinese menus, there really aren't that many options. It quite possibly might die on you, carts with internal memory do that sometimes.
This is all irrelevant though; DealExtreme has been sold out of the G6 Lite for months now, and they probably won't ever get more. I brought it up at the time because someone mentioned the G6 Lite, and that was a very good price for that cart.
