Hi all, I've currently got a DS Lite and am borrowing a friend's AceKard 2 as mine stopped working. I'm getting a 3DS XL for Christmas and want to get a new flashcart. I understand that you need to update the firmware on a DSTwo card before you update a 3DS XL. I'm a little confused where the older DS comes into play though - so if someone could explain that, I'd be really grateful. Also, will the DSTwo card work on a DS Lite regardless of what firmware it's running? So when I get it running on the 3DS XL, will the DSTwo card still work to play DS roms on my DS Lite? Hope this all makes sense!
