Every time I turn off my Dreamcast with the Visual Memory Unit still inserted into the controller, the VMU beeps loudly for a few seconds, and then asks me to enter the Time & Date again! It's not the batteries (I think), because I only replaced them about a month ago, and it'll still run anyway, so they're not flat. This happens every single time without fail!
Currently, the only way to avoid this is to take out the VMU and then turn off the Dreamcast - which is unbeliveably annoying! >
Can anyone help?!
