I have an ez flash 3in1+ that i got a couple months ago. Haven't had any problems with it since all i really wanted it for was to play gba games. i just have a quick question. does charging your ds with the 3in1 IN the ds make any difference in battery life for the 3in1? or should i leave the 3in1 OUT of the ds while i charge the ds? does it even matter one way or the other? i just wanna try to extend the battery life as long as possible so i don't have to worry about losing saves. i've heard different things about this so i just want to see what you guys say. Thanks.
