Okay well today my sister put about 12 new games on to her R4DS (She already have about 7), at first it worked fine. I went on a six hour bike ride and when I came home she told me none of her games we working. The games don't load, no white screen, no message, the blue bar doesn't even appear. The coloured balls spin for a little bit then stop moving totally and the R4 freezes. Only Moonshell loads. Do you know the solution? :/ Thanks in advance. I haven't tried anything yet.. My first attempt will be to take off all the games, then put 1 back on and see what happens. But If you have a better idea please tell me.
