I have a problem. My mom bought my nieces two DSi for Christmas and also got her an R4i Gold 3DS cart, which we bought from NDS-Card. They worked well, no problems up till now. The carts load up fine but whenever they play a game, game freezes at a white "Loading" screen. I'm not sure what the problem is exactly. I updated the firmware from the website thats printed on the cart (R4iDS.cn), I still get the same loading screen. It's been a while since I've actually messed with a flashcart but could this possibly have to do with the DSi firmware? One of them is on 1.4.3 and the other is on 1.4.4.
