I just received my g6 lite today and was loading the various builds of the loader. My lite is the Chinese version. It came with the 4.0a software loaded. I tried to load the 4.0c English version and it loaded but gave me the English language error others have been talking about. Then, I loaded the 4.0 beta loader described in this thread and it worked fine and 100 % in english. I had no problems with any of the 14 or 15 games that were loaded on it. I did have a problem with pocketnes and ebooks opening on the gba side but other emulators did work so I'm assuming there is a compatibility issue beyond my scope.
Also, I tried Mario Kart DS and got the same data related error many people had and confirmed that it was a problem with the rom. It seems the (U) version did not work but the (E) version did work. The game ran, WIFI worked, etc.
Other things. My G6 lite seems to have come with the "old" style casing instead of the one with holes in recent threads. Also, I put some .txt ebook files on the u drive and tried to read them in the gba media center area and was actually able to read one from the text file but others did not want to be read. Does anyone have any information on this reader in english? If I find more about this I'll let you know. A built in reader is a nice feature.
I really have no complaints at this point. I messed with the Chinese loader for a while before updating and it really didn't make much of a difference. You still have the icons of most games and it is possible to show the names of the roms in english. The important things you need to assign to the roms are in the pc software for the most part and that is completely in english.
