Hello, sorry about this noob question. I have a G6 Real, and I wanted to play some GBA games, so I bought an EZ 3 in 1 expansion pack. The only problem, is that i plug the 3 in 1 expansion pack on the slot 2, but my DS keeps saying that there is no cartridge on slot 2. Do i have to change the firmware of my DS or something like that? Thanks.
