VDFS: Changing VDFS root isn't kept if the emulator doesn't exit cleanly

[mark-usher]

If the VDFS root is changed it is not remembered by the emulator until the emulator is cleanly shut down. Thus if the VDFS root is changed, a program is run and it crashes, the emulator needs to have the VDFS root changed again when restarting.

I have pushed a commit, https://github.com/stardot/b-em/commit/a55f951169947fcd6e1dd67bbcb36f1c601e816f, to save the config file after a change of VDFS root. There are lots of other settings that are also not immediately saved - saving the config usually happens on exit and immediately before a change of model to the model-specific ROM config can be saved.

If you have found a reproducible way to crash the emulator itself so the config file is not saved then that would be worth reporting as a bug.

Thank you Steve. Primarily it is a bad program in development crashing the emulator as it would a real machine, rather than the emulator itself. The other scenario was if the PC goes into sleep mode, the emulator shuts down and the settings aren't saved. Serves me right for not staying at the computer longer. Would it be possible for the VDFS root selection dialog box to open at the currently selected location, or if not available the B-em directory?
