Problems in opening games in R4

Some of the games here just do not work for me. I am not sure why. whenever I try to open that particular game, all it says is: data cannot be accessed, please reinsert gamecard" or smth of that sort. however, this game can work for my frene. why is this so?? someone pls reply me. Thnx!!!

 

Maybe if you fix the arm 7 with ds lazy but most all games wont work as 100% good i have a m3 ds real sometimes when i play most games the sound sucks it plays some games good but i hate that my card reader blow up have you tried winrar ?
