...or is it just a marketing gimmick? According to product info, the firmware flasher can be used in case that Nintendo modifies their DS devices causing the flashcard to stop functioning. So, this means I can upgrade the firmware in case that I will buy any new DS model in the future and save about 20$ because I don't need a new flashcard, right? But why should I be unable to upgrade the firmware with my old DS, before using it with the new DS? After all, is the firmware really the only thing that needs to be changed? As far as I know, the difference between the Acekard 2 and Acekard 2i is not only the firmware but the internal structure of the card. Otherwise, the Acekard team could have just posted a new firmware on their website.
