Could playing my GBA SP while its charging maybe mess up the speaker from too much electricity going through the console? I noticed that while i was playing My Emerald cartridge the battery was getting low so i decided to plug in the charger but i didnt want to stop playing so i kept playing my game while it was charging. About 3 or 4 days later i noticed that the sound quality not in the game but from the actual console had gotten lower and at 1st i thought i was just imagining things but then i took my old SP and turned it on with my new SP (the one with the new screen) and yes noticed that the old SP's sounds was louder as was my new ones before. Could this be a problem from playing it while charging or could it of just happened as a flaw anyway? :\
