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 keyboard handler now properly emulates the //e's 2-key rollover.
However, we might have to add in a key repeat delay if it makes it so
that you can't type on the console anymore. This had to be done because
SDL will throw in key delay if you rely on it's SDL_KEYDOWN message and
this caused many games with keyboard input to be unplayable. Also, we
consolidated the video handling files, as there was very little in
video.cpp and so we moved it into applevideo.cpp and renamed that file
to video.cpp. Things are a lot cleaner as a result of this merge. :-)
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.
There was one bug that went undetected in the v65C02 core (in STX ZP,Y)
and another in the 80STORE handling (80STORE doesn't affect reading).
Also added a pause mode (bound to the Pause key), for those times when
you need to walk away from the emulation for a bit.
This involved fixing V65C02 (by subtracting out cycle overruns) and fixing
the main thread callback wait loop. As someone once said, "Threading is
hard." :-P
Before it was doing some complex timestamp thing, now it simple runs the
CPU for ~21 cycles and then stuff the sample into the sound buffer.
Sound still lags behind by several frames though, just like with the
previous sound setup. Still not sure why. :-/
