My bro was playing a gamboy color game on is SP when he Droped it by mistake he than picked it up, and it was forzen(wouldn't do any thing but still on) he turned off the SP and turned it back on(w/o a game in it) and it showed what it shows for a Gamboy. color he tried puting a Gamboy advance game in it and it still showed what it would show if it was a Gamboy color and it said there was no game in it! He got a little scared and thought it had to be a battery power thing so he charged it up and tried it again but he still showed what it shows for a Gamboy color! He tried using a gamboy color game and it worked fine but would never get it use a gamby advance game. this went on for about 4 days and was getting pretty mad/scared. he than showed it to my his Dad and he axcidently dropped it AGAIN! Every thing was blank for a second and then turned off. He turned it back on and it was back to normal! He was pretty glad at that time =P has somthing like this ever happend to you???
