      byuu says:
        - processor/huc6280,mos6502,wdc65816: replaced abbreviated opcode
          names with descriptive names
        - nall: replaced `PLATFORM_MACOSX` define with `PLATFORM_MACOS`
        - icarus: added `Icarus::missing() -> string_vector` to list missing
          appended firmware files by name
        - ruby, hiro: fix macosx→macos references
      The processor instruction renaming was really about consistency with the
      other processor cores. I may still need to do this for one or two more
      The icarus change should allow a future release of the icarus
      application to import games with external SNES coprocessor firmware once
      again. It will also allow this to be possible when used in library mode.

        - nall/GNUmakefile: build=release changed to -O2, build=optimize is
          now -O3
        - hiro: added Monitor::dpi(uint index) → Position [returns logical
          DPI for x, y]
            - Position is a bad name, but dpi(monitor).(x,y)() make more sense
              than .(width,height)()
        - hiro: Position, Size, Geometry, Font changed from using signed int
          to float
        - hiro: Alignment changed from using double to float
        - hiro: added skeleton (unused) Application::scale(), setScale()
        - hiro/cocoa's Monitor::dpi() is untested. Probably will cause issues
          with macOS' automatic scaling.
        - hiro/gtk lacks a way to get both per-monitor and per-axis (x,y) DPI
        - hiro/qt lacks a way to get per-monitor DPI scaling (Qt 5.x has this,
          but I still use Qt 4.x)
            - and just to get global DPI, hiro/qt's DPI retrieval has to use
              undocumented functions ... fun
      The goal with this WIP was basically to prepare hiro for potential
      automatic scaling. It'll be extremely difficult, but I'm convinced that
      it must be possible if macOS can do it.
      By moving from signed integers to floats for coordinates, we can now
      scale and unscale without losing precision. That of course isn't the
      hard part, though. The hard part is where and how to do the scaling. In
      the ideal application, hiro/core and hiro/extension will handle 100% of
      this, and the per-platform hiro/(cocoa,gtk,qt,windows) will not be aware
      of what's going on, but ... to even make that possible, things will need
      to change in every per-platform core, eg the per-platform code will have
      to call a core function to change geometry, which will know about the
      scaling and unscale the values back down again.
      Gonna be a lot of work, but ... it's a start.

        - tomoko: reduced volume slider from {0% - 500%} to {0% - 200%}.
          Distortion is too intense above 200%.
            - technically, I've encountered distortion at 200% as well in
              Prince of Persia for the SNES
        - nall/run/invoke: use program path for working directory
            - allows you to choose “Library→Import ROMs” from a different
              directory on the command-line
      I don't know how to assign credit for the mosaic stuff. It's been a
      work-in-progress with me, Cydrak, and hex_usr.
      The current design should be correct, but very unpleasant. The code
      desperately needs to be refactored, but my recent attempt at doing so
      ended in spectacular failure.

      Turns out there is only one mosaic size, and the other four bits are
      per-BG mosaic enable. This matters a lot for hires/interlace, as
      mosaicSize=0 (2x2) is not the same thing as mosaicEnable=false (1x1).
      Although I've now implemented this, I really don't like how my mosaic
      implementation works right now. I tried to redesign the entire system,
      and completely failed. So I started over from v104r10 again and instead
      went with a more evolutionary improvement for now. I'll keep trying.
      Also, the combination of mosaic + offset-per-tile is still sketchy, as
      is mode 6 offset-per-tile. I'll get to those in the future as well.

        - resource: recreated higan+icarus icons, higan logo as 32-bit PNGs
      So higan v104r08 and earlier were 930KiB for the source tarball. After
      creating new higan and icarus icons, the size jumped to 1090KiB, which
      was insane for only adding one additional icon.
      After digging into why, I discovered that ImageMagick defaults to
      64-bit!! (16-bits per channel) PNG images when converting from SVG.
      You know, for all those 16-bit per channel monitors that don't exist.
      Sigh. Amazingly, nobody ever noticed this.
      The logo went from 78.8KiB to 24.5KiB, which in turn also means the
      generated resource.cpp shrank dramatically.
      The old higan icon was 32-bit PNG, because it was created before I
      installed FreeBSD and switched to ImageMagick. But the new higan icon,
      plus the new icarus icon, were both 64-bit as well. And they're now
      So the new tarball size, thanks to the logo optimization, dropped to
      Cydrak had some really interesting results in converting higan's
      resources to 8-bit palletized PNGs with the tRNS extension for alpha
      transparency. It reduces the file sizes even more without much visual
      fidelity loss. Eg the higan logo uses 778 colors currently, and 256
      represents nearly all of it very well to the human eye. It's based off
      of only two colors, the rest are all anti-aliasing. Unfortunately,
      nall/image doesn't support this yet, and I didn't want to flatten the
      higan logo to not have transparency, in case I ever want to change the
      about screen background color.

      Note: the S1/OV1 emulation is likely not 100% correct yet, but it's a

      shouldn't result in any issues, I'd just like to have this part of the
      chip emulated correctly.

        - icarus/sfc: request sgb1.boot.rom and sgb2.boot.rom separately; as
          they are different
        - icarus/sfc: removed support for external firmware when loading ROM
      The hack to run Mega Drive Ballz 3D isn't in place, as I don't know if
      it's correct, and the graphics were corrupted anyway.
      The SGB boot ROM change is going to require updating the icarus database
      as well. I will add that in when I start dumping more cartridges here
      Finally ... I explained this already, but I'll do so here as well: I
      removed icarus' support for loading SNES coprocessor firmware games with
      external firmware files (eg dsp1.program.rom + dsp1.data.rom in the same
      path as supermariokart.sfc, for example.)
      I realize most are going to see this as an antagonizing/stubborn move
      given the recent No-Intro discussion, and I won't deny that said thread
      is why this came to the forefront of my mind. But on my word, I honestly
      believe this was an ineffective solution for many reasons not related to
      our disagreements:
       1. No-Intro distributes SNES coprocessor firmware as a merged file, eg
          "DSP1 (World).zip/DSP1 (World).bin" -- icarus can't possibly know
          about every ROM distribution set's naming conventions for firmware.
          (Right now, it appears GoodSNES and NSRT are mostly dead; but there
          may be more DATs in the future -- including my own.)
       2. Even if the user obtains the firmware and tries to rename it, it
          won't work: icarus parses manifests generated by the heuristics
          module and sees two ROM files: dsp1.program.rom and dsp1.data.rom.
          icarus cannot identify a file named dsp1.rom as containing both
          of these sub-files. Users are going to have to know how to split
          files, which there is no way to do on stock Windows. Merging files,
          however, can be done via `copy /b supermariokart.sfc+dsp1.rom
          supermariokartdsp.sfc`; - and dsp1.rom can be named whatever now.
          I am not saying this will be easy for the average user, but it's
          easier than splitting files.
       3. Separate firmware breaks icarus' database lookup. If you have
          pilotwings.sfc but without firmware, icarus will not find a match
          for it in the database lookup phase. It will then fall back on
          heuristics. The heuristics will pick DSP1B for compatibility with
          Ballz 3D which requires it. And so it will try to pull in the
          wrong firmware, and the game's intro will not work correctly.
          Furthermore, the database information will be unavailable, resulting
          in inaccurate mirroring.
      So for these reasons, I have removed said support. You must now load
      SNES coprocessor games into higan in one of two ways: 1) game paks with
      split files; or 2) SFC images with merged firmware.
      If and when No-Intro deploys a method I can actually use, I give you all
      my word I will give it a fair shot and if it's reasonable, I'll support
      it in icarus.
