Hello, I can't really find any info on this device by googling or digging through the forum. - I have two fresh AAs in the device, but the red LED comes on as soon as I turn on the console. Wasn't this supposed to be a low battery indicator? Or is that just when the console is off and its a power LED otherwise? - Can I swap batteries while retaining the data? Is there like a backup capacitor or something? - Is there a build-in file manager or any other way to test that the unit is working? I only have a single JP language game that has save support and I'd just like to test if the device is working properly. Thanks!
