This is significant and probably gives the R4i 3DS team a bit more respect; this means that the components they’re using to build the R4i 3DS / R4i SDHC cards are now better.
However, if your DSi is already updated you must borrow a DS Lite, 3DS, or DSi v1.4.1 or lower.
You cannot update your R4i card using a Nintendo DSi console that is already using the 1.4.2 firmware.
Download the fix file from the R4i official website here and copy it onto the Micro SD card with your R4i menu files. Don’t forget you need to unzip the files using a program like Win RAR or Win ZIP.
This is a great and welcome change, and we’re happy to welcome the R4i into the “updatable” fold.
We’ll show you how to update your R4i card here, it will give you full access to your card features on your updated DSi console.
