Hello, I own a R4 SDHC 3DS/DSi flashcard from 2013. Since all the games were corrupted (or almost there), I decided to format it.Problem is, when I looked up the website of the R4, the firmware for this old version wasn't downloadable nor supported. So I tried to install the Wood version, but when playing the flashcard, it's only stuck to a 'loading...' screen. Can you help? thanks in advance
