Hey the1dog, does ure r4 card have an i or wifi on it or is it just plain r4?(check the sticker on the face of u're card, the difference means different software to run it. Just go to this site and see which one matches
the sticker on urer4 card download,extract it and put it on the root of ure micro sd card, create a games folder on ure sd card as well extract the ds games u want and drop them in the games folder and that's basically it! The important part is to pick the correct kernel that matches u're card sticker!
