The menu problem usually means the firmware files are incorrect. but because the card is from r4-factory which is really not a good card. they have stopped updating for long time, and their firmware is too old. i recommend you just format your sd card, then use the latest firmware and try again, if still not working, i recommend you just buy another better card. Currently the best flashcarts are r4i gold 3ds cart R4i Gold 3DS Wood R4i 3DS flashcard For DS DSi 3DS -dsflashcart.com or supercard dstwo. both of them are working great on your Dsi V1.43U, and both of them update regularly.
