Lately m6 G6 lite has been acting up. It saves fine but some games just randomly freeze and when I turn it back on only the top screen boots and nothing else happens. Even when I start in GBA mode all I get is a black screen. I've updated both loader and software on my G6 to the latest but I can't figure out whats wrong. Sometimes it U-Disk doesn't even read it. Should I format it? How do I format it? Any suggestions?
