I have a DS lite.
I'm getting a passkey 3.

What are the differences between these 2 SuperCard things from linker4u.com?:
supercard Lite and EWin2? which is better?

and is there something like this, but uses normal SD cards?

could I play ds and gba roms with this stuff?

does datel's max media launcher need a supercard and can it play ds and gba roms?
