You need another DS/DS Lite/DSi that the card already works on, run the newest update. After that, the card will work on the newest firmware the update is compatible with...which seems to be Nintendo's 4.0.0.7 update, according to gbatemp forum users.

You can make a post on the DS forum about your findings, and they'll do their best to respond. They have a GBAtemp account here, you know. -

Well, from what I've heard from my parents, he had a seizure last night, perhaps an epileptic episode, fucking died, had a near death experience, my dad called the paramedics, they showed up, took him to the hospital, and he woke up covered in tubes, and started complaining.
