My sister upgraded her DSi, and can no longer use her R4. Is there any way to update the R4? I assume there's got to be. Thanks. -Dan
if it is an original R4 then no. If it is an R4i then it can be updated using a DS or a non-updated DSi.
there should be an update for the dsi 1.4.1 firmware on your cards official website if not i cant help you
