i got 3 game sharks version 3.3 but only 1 of them seems to boot. if i try using the non working ones i get nothing. not really sure if there is a way to fix this. i don't remember seeing any broken solder joints when had the covers off. i did notice it did not have the display like the working game shark but from what i read the number display is just a older version that has been re flashed. tried all the games i have with them and nothing. don't know where to go from here.
