Hi All I'm new to this but i recently got a r4i ultra and r4i gold card i have used the r4 cards and the games played fine. but with the new nintendo dsi all i seem to get is a black screen with the word Loading... nothing happens no matter which card i use or how long i leave it running.
They probably are not 1.4 firmware compatible - the new DSi will have the latest. Look for an upgrade to the Kernal but I believe they have just issued new cards, so they can only be used on DS or early DSi. Try and AceKard, EZ Flashvi or M3Zero next time - they can be upgraded
