last night my wife tried playing sonic cd, it booted up fine then got a screen that said your internal ram is not initialized, use the control panel to initialize your ram. she couldn't get any farther. so i tried to go to the control panel but i can't get it up. so i put lunar 2 told it to continue and all my save slots were gone. so then i tried dark wizard. but it couldn't even find my backup cart. so who think the internal ram in my cdx is fried?? or is there a backup battery that might need replacing??
