The newer flashcarts are DSi enabled. (example: R4 --> R4i) I'm not sure if it's a whole new card or just a firmware upgrade, but I went ahead and ordered an enabled one since it was only $2 extra.
As for already owning a DS Lite, if I need to do a trade-in then it doesn't matter what I have right now, since I'm trading it in.
I just need to decide if it's worth throwing an extra 40 bucks in.:what:
The R4i isn't a real R4 it's just a clone FlashCart with several issues. The only real R4 are the only say R4 so if it says R4 3 or R4 Gold ect it's a fake. Most R4 clones just lock up and ruin everything that's on the MicroSD card.
The Acekard2i is in my opinion the best DSi FlashCart.
So are you getting a DS lite or a DSi? I'm confused ._.
