Known issues

If you use sbtool in conjunction with edb, for example loading OSLoader into calculator's RAM, there's a chance that the ExistOS disk cannot be mounted properly.

To circumvent this, put a battery into the compartment (if there isn't any), unplug & replug the USB cable, then try again. That should be it.
