It can be 4.5.0 or lower, I'm not sure what the lowest possible firmware is for a SW12 3DS XL but then again it does not matter since it doesn't get below 4.1.0.
Ok so i went to meijer for some 2/ $5 gallon of ice cream decided to head over to the electronics section.
only 1 guy working no one else in there asked if he could help me find a specific make of 3ds XL
first one was:SW40
a couple were: SW13
i believe there were 1 or 2 sw12's in there as well.
will sw13 work? and whats s40 lol>?
