I've just bought my son a DSi XL for christmas and I would be grateful for a little advice please. He currently owns a DS Lite which has an R4 flashcart running Wood with DScovered to help him navigate the menus (he's only 6). I'm aware that I will need to buy an R4i card to work with the DSi XL but would I be able to take the existing microsd card from the R4 card and use it in the R4i? If the version of Wood that is on the R4 flashcart is not compatible, would I just be able to update Wood and everything else (DScovered, games) will work on the DSi? The DSi is running firmware version 1.4.4E. Thanks for any help.
