Ok so I owned a nintendo ds lite a LONG time ago and just like a week ago I thought to myself "man.. I really miss that DS" so I bought two DS's on ebay for $60 (It was a nintendo DS Lite and Nintendo DSi and they both work perfectly) ok now... I heard that if I wanted to get a supercard dstwo and use it for both then I had to get a certain GB storage space limit on a MicroSD card. For example if I used it on my dslite then I would have to get a 2GB or less? Or does it matter which one I get? Could I get an eight GB MicroSD card and use that for both DS's? or do I need seperate microsd cards for each one?
