Hi I put some games on an R4 Upgrade for a friend for his Nintendo DS Lite. It has been working fine for months until he said all his games have disappeared. He said he did not wipe any of them off. On the start up screen it says 'There is no DS card inserted' My R4 works fine in his DS. So I then put the micro sd chip in the removeable device in the computer. Some games were corrupted so I just deleted everything from the chip & started again. The same problem is happening its says 'There is no DS card inserted' What could be the problem? Could the corrupted games ruined the R4 cartridge? Any advice please? Thank you
its doubtful that the R4 Card is damaged try a new Micro SD card I have seen plenty of those fail in my time
