I think its good to have the R4I card specially for the kids my lad scratch's breaks ever game he plays on with out fail I tell people not to buy games for his dsi as he just breaks thm cost me over 200 in replacing games no matter how many times I say be careful look after it with 2 hours DAAAAAAAAAAAAAADDDD its not working he is 7 but still burns a hole in my pocket so become cheaper getting the R4I card only 20 squid could of got 10 the amount I spent replacing his games now I got this dosnt need to remove it at all unless he wants a new game.
