so i bought this transparent case for my ds lite. i have a flashed ds lite and a supercard sd. a guy changed the case for me... now when i turn my ds lite with my supercard in it ...it shows two blank screens. when i turn my ds lite with a gba game... it plays ok. when i turn my ds lite with a ds game... it plays ok. but when the supercard is in it BLANK SCREENS... so... what happened? did the guy who installed the case changed the board without telling me with a non-flashed one? or what could have happened that made my ds lite stop recognizing my supercard?
