Thanks for all the help/advice!!!!!!! I will purchase one soon. If any one can help me with one last thing that would be great. i notice that some cards want to add on sd micro with purchase. do i need to add one on if i own one already and if so does size matter (thats wat she said lol sorry...)
you don't need to purchase it from the store, that is a regular micro sd card, you can purchase it where do you want. i don't recomend you buying from theese sites, they usually send you a counterfeit one.. (from example, it looks like it's from Kingston but its fake..) i had experience with a fake one and i don't recomend it..
if you cap purchase the card from a retail store or any other more trustable place it should be fine..
as for the size of the micro sd card. it depends what flashcart you purchase. if you purchase a DSTWO you can use any micro sd card up to 32GB (i dont know if they support sdxc).
if you buy a r4, that depends.. the normal rule is: cards up to 2gb are normal sd cards. cards from 2gb to 32gb are SDHC, more than 32gb is SDXC
if the r4 is very old or really cheap, it can't support SDHC..
thats why you should get a DSTWO. i own it. and don't regret paying the much i paid.. you don't have to deal wich 4r you should buy, or dig looing for firmware.. or worry about a new 3DS update block it... if a new firmware comes out for the 3ds, all you need is, not update teh console, go into the supercard website and check if it needs to update, if needs to update, you update the card then the console and done...
with r4 clones they can be blocked and can stop working forever on your console making you buy a new one...
but nintendo did take a break on his fight against flashcarts... maybe they will not block ds cards anymore but this is a magic ball conversation so...
