Apologies if this is covered elsewhere, I have read the FAQ. We've had an Edge card for years using it on a DSI. Just bought a 3DS and an R4i Gold Plus Deluxe card. Put the v2.8 kernel on the card and transferred all the ROMs I was using on the Edge card to the R4i Gold. Mostly works fine, but the newer games don't work - for example 6116 - Lego LOTR, 6125 - Ben 10. The other thing I don't understand is what the "Firmware upgrade writer" is? Thanks in advance.
