I've had this r4 for a good year so far, I probably won't be getting a new one. I specifically got it for my DSi. I checked my DSi's info and it was still on 1.3.. I was thinking.. does keeping it on 1.3 do anything? Or should I go ahead and go to 1.4? (R4i has 1.4 firmware. ) Will it make a difference? Like let me play different games?
