- Vertical overscan masking is now adjustable. 0, 8, 12, or 16 pixels
may be masked from both the top and bottom of the video output.
- Aspect ratios are now calculated correctly, and the proper pixel
aspect ratio will now be applied regardless of overscan settings.
The 4:3 option will just use a 4:3 display aspect ratio regardless
of overscan settings.
- Base sizes have been adjusted to reflect the ideal base sizes rather
than the doubled sizes used internally. This makes the initial window
size what one would reasonably expect instead of being doubled.
- Masking off the Super Game Boy border now works as it should. The
aspect ratios chosen for general usage will apply to the masked SGB
video output. The NTSC filter will now also work properly with this
mode active. Additionally, this setting is now independent from the
general overscan masking setting.
anomie's notes indicate that polling begins between cycles 32.5-95.5, but his
notes were slightly off. 32.5-95.5 is referring to the PPU dot clock. If you
multiply by 4 you get the cycle count, 130-382. It's pretty clear that in
256-cycle units, that would need to be 130-384 or you'd have no event when it
lands on cycle 384. Jonas Quinn confirmed that with his testing in any case.
I chose to split the cycle range in half and run things every 128 clocks. So
that reduces us to 32.5-64.0, or 130 to 256 + 258-384. The reason I chose 128
over 256 was so I could emulate the time it takes to perform the joypad
latching. I don't believe you can set the controller latch to 1 and then 0
immediately. It needs time to let the controllers see this happening and then
release the latch, and time to let that take effect. Polling the controllers is
only one operation so it makes sense that happens once every 256 cycles, which
is why I have the (counter&1) test for that.
Think about it this way: we know the polling sequence takes 4224 cycles, and
4224/256 is 16.5. Isn't that a little strange to have half a cycle? But if we
consider the latching is actually twice as fast, then it's 2x128 + 16x256. If we
run on a 128-clock counter, it becomes 2x128 + 16x2x128, or 34 total states. But
now since we don't actually poll on the second half of each 16x2x256 states, we
don't need to bother running the event there, so we can stop at 33 instead of 34
and it's the same thing. And by doing that, it turns our polling duration into
4224 cycles, just like we've observed.
