Changelog:
- Super Game Boy: for the 50th time, higan won't segfault if you
cancel the Game Boy cartridge load request
- icarus: moved to new manifest syntax for all remaining systems
- Game Boy: moved to new manifest syntax
Errata:
- Game Boy: save RAM does not appear to be working for some reason
- Famicom: higan won't even start to run this system; it just acts
like a cartridge was never loaded ...
- cores outside of the Super Famicom and Game Boy/Color will not run
due to icarus/higan manifest syntax differences

Changelog:
- Emulator::Interface::videoResolution() -\> VideoResolution renamed
to videoInformation() -\> VideoInformation
- added double VideoInformation::refreshRate
- higan: added `binary := (application|library)` — set this to
`library` to produce a dynamic link library
- higan: removed `-march=native` for macOS application builds; and for
all library builds
- higan: removed `console` build flag; uncomment `link += -mwindows`
instead
- nall/GNUmakefile: `macosx` platform renamed `macos`
- still need to do this for nall/intrinsics.hpp
- Game Gear: return region=NTSC as the only option, so that the system
frequency is always set correctly
- hiro/cocoa: fixed typo [Sintendo]
- hiro/Windows: removed GetDpiForMonitor, as it's Windows 8+ only; DPI
is no longer per-monitor aware
- icarus: core Icarus class now has virtual functions for
directory::create, <file::exists>, <file::copy>, <file::write>
- icarus: Sufami Turbo can import save RAM files now
- icarus: setting `ICARUS_LIBRARY` define will compile icarus without
main(), GUI components
- ruby/video/Direct3D: choose the current monitor instead of top-left
monitor for fullscreen exclusive [Cydrak]
- ruby/video/Direct3D: do not set `WS_EX_TOPMOST` on fullscreen
exclusive window [Cydrak]
- this isn't necessary for exclusive mode, and it just makes
getting out of the application more difficult

Changelog:
- hiro: BrowserDialog can navigate up to drive selection on Windows
- nall: (file,path,dir,base,prefix,suffix)name =>
Location::(file,path,dir,base,prefix,suffix)
- higan/tomoko: rename audio filter label from "Sinc" to "IIR - Biquad"
- higan/tomoko: allow loading files via icarus on the command-line
once again
- higan/tomoko: (begrudging) quick hack to fix presentation window focus
on startup
- higan/audio: don't divide output audio volume by number of streams
- processor/r65816: fix a regression in (read,write)DB; fixes Taz-Mania
- fixed compilation regressions on Windows and Linux
I'm happy with where we are at with code cleanups and stability, so I'd
like to release v100. But even though I'm not assigning any special
significance to this version, we should probably test it more thoroughly
first.

Absolutely major improvements to the WS/C emulation today.
Changelog: (all WS/C related)
- fixed channel 3 sweep pitch adjustment
- fixed channel 3 sweep value sign extension
- removed errant channel 5 speed setting (not what's really going on)
- fixed sign extension on channel 5 samples
- improved DAC mixing of all five audio channels
- fixed r26 regression with PPU timing loop
- fixed sprite windowing behavior (sprite attribute flag is window mode;
not window enable)
- added per-scanline register latching to the PPU
- IRQs should terminate HLT even when the IRQ enable register bits are
clear
- fixed PALMONO reads
- added blur emulation
- added color emulation (based on GBA, so it heavily desaturates colors;
not entirely correct, but it helps a lot)
- no longer decimating audio to 24KHz; running at full 3.072MHz through
the windowed sinc filter [1]
- cleaned up PPU portRead / portWrite functions significantly
- emulated a weird quirk as mentioned by trap15 regarding timer
frequency writes enabling said timers [2]
- emulated LCD_CTRL sleep bit; screen can now be disabled (always draws
black in this case for now)
- improved OAM caching; but it's still disabled because it causes huge
amounts of sprite glitches (unsure why)
- fixed rendering of sprites that wrap around the screen edges back to
the top/left of the display
- emulated keypad interrupts
- icarus: detect orientation bit in game header
- higan: use orientation setting in manifest to set default screen
rotation
[1] the 24KHz -> 3.072MHz sound change is huge. Sound is substantially
improved over the previous WIPs. It does come at a pretty major speed
penalty, though. This is the highest frequency of any system in higan
running through an incredibly (amazing, yet) demanding sinc resampler.
Frame rate dropped from around 240fps to 150fps with the sinc filter on.
If you choose a different audio filter, you'll get most of that speed
back, but audio will sound worse again.
[2] we aren't sure if this is correct hardware behavior or not. It seems
to very slightly help Magical Drop, but not much.
The blur emulation is brutal. It's absolutely required for Riviera's
translucency simulation of selected menu items, but it causes serious
headaches due to the WS's ~75hz refresh rate running on ~60hz monitors
without vsync. It's probably best to leave it off and just deal with the
awful flickering on Riviera's menu options.
Overall, WS/C emulation is starting to get quite usable indeed. Couple
of major bugs that I'd really like to get fixed before releasing it,
though. But they're getting harder and harder to fix ...
Major Bugs:
- Final Fantasy battle background music is absent. Sound effects still
work. Very weird.
- Final Fantasy IV scrolling during airship flight opening sequence is
horribly broken. Scrolls one screen at a time.
- Magical Drop flickers like crazy in-game. Basically unplayable like
this.
- Star Hearts character names don't appear in the smaller dialog box
that pops up.
Minor Bugs:
- Occasional flickering during Riviera opening scenes.
- One-frame flicker of Leda's sprite at the start of the first stage.

This is a few days old, but oh well.
This WIP changes nall,hiro,ruby,icarus back to (u)int(8,16,32,64)_t.
I'm slowly pushing for (u)int(8,16,32,64) to use my custom
Integer<Size>/Natural<Size> classes instead. But it's going to be one
hell of a struggle to get that into higan.
byuu says:
More V30MZ implemented, a lot more to go.
icarus now supports importing WS and WSC games. It expects them to have
the correct file extension, same for GB and GBC.
> Ugh, apparently HiDPI icarus doesn't let you press the check boxes.
I set the flag value in the plist to false for now. Forgot to do it for
higan, but hopefully I won't forget before release.
