I've installed the new operating system onto a new micro SD card, but I cant work out how to copy the original ROMs from the SD card that came with the system. It doesn't show up when I put it in my PC, so I cant copy it to there to transfer over to the new one, and I've tried to do it on the rs-97 itself, but the card doesn't show up anything when I look at the external SD card with the original put into the cartridge. I haven't got any other ROMs to put on the new set up, so I've had to put the old card back in to play games. Please help, I need an idiots guide to get me through!
