Hello, I'm incredibly sorry for my lack of knowledge, but soon I will be going to a foreign country to study and I want to bring a gaming system with me. Thus I have decided to buy a 3DS so I can play the countless great titles that have released on it over the years. However, I'm a complete noob when it comes to using R4's with the system. Obviously playing games for free would be in my best interests, but I don't want to spend money on a 3DS only to find out an R4 card won't work with the current hardware version etc. So, can someone please point me in the direction of a complete guide for new 3DS buyers?
