Hi Im totally new to this flash card world so bare with me (: I have a NDS Lite. I got a new flashcard (this http://www.r4isdhc.com/2014-r4isdhc-gold-pro/) that seems legit and bought a 8gb micro sd card. Formatted it through SDFormatter 4.0 on my Mac. Choose the Overwrite format. And after that I unzipped and put the 'R4i-V3.7b English' files on there. Then some '.nds' games in the root folder. When i try to start the games i get this errcode 83 and 81 saying I could format them and there are some fragmentation errors on the sd card. Have tried formatting the card several times but no luck. I have managed to get one game started and I think that was when I did a new overwrite format, then just transfered one '.nds' game file to the root and tried. But after putting another rom on there the error showed up again. How do I solve this? Thanks a lot in advance!
