Hello, so basically i happened to stumble across an r4 card, now i haven't owned one before and i have no idea how to use one, by the way i think it is one of the newest versions because it says "R4i 3DS Revolution for DS (N3DS/NDSi XL/NDSL/NDS) www.r4ids.com" on it, it already had a few games on it but i wanted some more, anyways i youtubed a few videos and ended up downloading winRAR, and went on ndsuniverse.com and downloaded 2 games to see if it worked, it said there wasnt anymore room on the sd card, its 2gb and there were only a few games on it. So i took one of my own micro sd cards and tried downloading the games on there, they are on the sd card but when i put the sd card inside the r4 card and try to play it all i get is a "loading..." and it never ends up loading, so i'm not sure what is wrong with it, and i guess i'm doing it wrong. If anybody has any tips please let me know. I would like to download more games on it.
