The settings code now actually saves updated settings to the config
file. Also wrote the beginnings of a proper Config window, and a few
of the options actually work (which ones work is left as an exercise
for the reader).
Having taken a good look at "Understanding the Apple IIe", I've fixed
the timing of one frame now that I know how much time it's supposed to
take. Also added the ability to recurse into subdirectories of the disks
directory, and the ability to page through the disk list when there are
more than three columns of disks. Another thing I did not know about was
Double LoRes, that has been added as well; also, did not know that the
video bus appeared at memory mapped locations that weren't attached to
anything. This quirk is now properly emulated.
The idea is to present icons for the most commonly used functions that
will pop up on the screen when moused over, then go away once the mouse
is not over them anymore. Hopefully this will actually be usable, unlike
the previous clusterfuck that I attempted. It was a good idea, but SDL
just wasn't up to the heavy lifting required.
