Hello everyone, I bought this card calls R4i II sdsh .. web.. http://www.r4i-sdhc.com.hk/ i have a NDSI, this card worked perfectly until I upgrade the NDSI .. i have v1.4 now and this card does not work anymore. i have read that there are a lot of fake cards and i think mine is one of them. i have opened it and have a cfeon micro chip. In the box says that i can upgrade the core to use it with the new version but i do not know how to do it. can you help me? can i do something or i just need to buy a new one? any help. thanks.
