I've read around, and it looks like the G6 Lite is the cart to buy for the DS Lite. I've had carts for the GBA, easy enough to use, but for the DS, I've seen talk of needing a seperate card (passcards, etc), and/or flashing the DS firmware. Anywhere on these forums that have a quick explanation of all this, and if not, could someone give a quick explanation? Would a G6 Lite, and a Passcard 3 be enough to play games (including online games), or do have I have to do anything else, like flashing the DS firmware?
