It usually doesn't matter about which card you have, all that matters is if the card will receive updates, whether its by the developers or just normal homebrewers out there. Usually for cards that don't receive updates from the developers will still be updated by a hacker. Such as the R4, the developers gave up on it a long time ago yet there are hackers that keep the project alive and increase compatibility with the card. Also if you card is really outdated it won't work on the DSi, though if you do actually mean Lite it should work.
