there are dump programs, but if they work on the g6 lite I don't know.
I've used my M3 slim sd to dump, but it was a dumper made just for m3 sd carts.
I think new nds cart may have new copy protection on them, because I tried to dump Asphalt 2 Urban GT yesterday, and it almost completes, but then it just hangs.
If you want the 3 different dump programs that I have just send me a pm and I will send you a link for them.
