So I've flashed 2 ds lites successfully off a superkey and supercard sd. I don't find the supercard sd to protrude from the dsl any more annoyingly than a minisd supercard. I do hear some people say they like the supercard minisd better because it has a batter to backup your sram data. I like that I can get 4gb sd cards and am inclined to prefer regular sd. What I have yet to figure out is just what is stored in the sram and how this inconveniences me by not having the battery.
