Hi everyone, I bought a r4i dual core a week ago but also ordered a r4i gold card because I updated my ds to 4.5.0 and there wasn't an update for the dual core card yet. Now I've got 2 cards as of today but I also see that there is an update for my dual core chip. Both cards can be send back within 14 days. My question is which one is best to keep? Hope you guys can help me out. greetings.
