I am getting my son a DSi and a SupercardDSTWO. I know how to download and apply a different theme, and also how to get games on there but is there anything else that I should be doing to it? I'm trying to get the most functionality out of the device. I am traveling on a 30 hour road trip, I have a 5 and 4 year old, so keep that in mind that usability is for that age. Thanks a ton!!!!
