PLEASE READ:

I originally gave the card a 67% because Pokémon White didn't work, which should work on any firmware right now. But now it seems that there was something wrong with my ROM, so I got a crisp clean ROM and it did work, it didn't freeze. So now my whole point of view of this card changes: I thought it had just average NDS ROM compatibility because and old game like Pokémon White didn't work, but seeing now that is was my own fault by not using a clean ROM I think it has good to great NDS ROM compatibility.

I changed the rating up to 70% because this IS a good card, and it is really cheap. If you're looking for a cheap card with good ROM compatibility, this might be the card for you.
