The main thing I worked on today was emulating the MBC7 EEPROM.
And... I have many things to say about that, but not here, and not now...
The missing EEPROM support is why the accelerometer was broken. Although
it's not evidently clear that I'm emulating the actual values
incorrectly. I'll think about it and get it fixed, though.
bsnes went from ~308fps to ~328fps, and I don't even know why. Probably
something somewhere in the 140KB of changes to other things made in this
WIP.

Changelog:
- NES PPU core updated to use BitFields (absolutely massive improvement
in code readability)
- NES APU core updated to new coding style
- NES cartridge/board and cartridge/chip updated to new coding style
- pushed NES PPU rendering one dot forward (doesn't fix King's Quest V
yet, sadly)
- fixed SNES PPU BG tilemask for 128KiB VRAM mode (doesn't fix Yoshi's
Island, though)
So ... I kind of went overboard with the fc/cartridge changes. This WIP
diff is 185KiB >_>
I didn't realize it was going to be as big a task as it was, but once
I started everything broke in a chain reaction, so I had to do it all
at once.
There's a massive chance we've broken a bunch of NES things. Any typos
in this WIP are going to be absolutely insidious to track down =(
But ... supposing I pulled it off, this means the Famicom core is now
fully converted to the new coding style as well. That leaves only the
GB and GBA cores. Once those are finished, then we'll finally be free
of these gigantic hellspawn diffs.

New update. Most of the work today went into eliminating hiro::Image
from all objects in all ports, replacing with nall::image. That took an
eternity.
Changelog:
- fixed crashing bug when loading games [thanks endrift!!]
- toggling "show status bar" option adjusts window geometry (not
supposed to recenter the window, though)
- button sizes improved; icon-only button icons no longer being cut off

I'll post more detailed changes later, but basically:
- fixed Baldur's Gate bug
- guess if no flash ROM ID present (fixes Magical Vacation, many many
others)
- nall cleanups
- sfc/cartridge major cleanups
- bsxcartridge/"bsx" renamed to mcc/"mcc" after the logic chip it uses
(consistency with SGB/ICD2)
- ... and more!

This will easily be the biggest diff in the history of higan. And not in
a good way.
* target-higan and target-loki have been blown away completely
* nall and ruby massively updated
* phoenix replaced with hiro (pretty near a total rewrite)
* target-higan restarted using hiro (just a window for now)
* all emulation cores updated to compile again
* installation changed to not require root privileges (installs locally)
For the foreseeable future (maybe even permanently?), the new higan UI
will only build under Linux/BSD with GTK+ 2.20+. Probably the most
likely route for Windows/OS X will be to try and figure out how to build
hiro/GTK on those platforms, as awful as that would be. The other
alternative would be to produce new UIs for those platforms ... which
would actually be a good opportunity to make something much more user
friendly.
Being that I just started on this a few hours ago, that means that for
at least a few weeks, don't expect to be able to actually play any
games. Right now, you can pretty much just compile the binary and that's
it. It's quite possible that some nall changes didn't produce
compilation errors, but will produce runtime errors. So until the UI can
actually load games, we won't know if anything is broken. But we should
mostly be okay. It was mostly just trim<1> -> trim changes, moving to
Hash::SHA256 (much cleaner), and patching some reckless memory copy
functions enough to compile.
Progress isn't going to be like it was before: I'm now dividing my time
much thinner between studying and other hobbies.
My aim this time is not to produce a binary for everyone to play games
on. Rather, it's to keep the emulator alive. I want to be able to apply
critical patches again. And I would also like the base of the emulator
to live on, for use in other emulator frontends that utilize higan.

New terminal is in. Much nicer to use now. Command history makes a major
difference in usability.
The SMP is now fully traceable and debuggable. Basically they act as
separate entities, you can trace both at the same time, but for the most
part running and stepping is performed on the chip you select.
I'm going to put off CPU+SMP interleave support for a while. I don't
actually think it'll be too hard. Will get trickier if/when we support
coprocessor debugging.
Remaining tasks:
- aliases
- hotkeys
- save states
- window geometry
Basically, the debugger's done. Just have to add the UI fluff.
I also removed tracing/memory export from higan. It was always meant to
be temporary until the debugger was remade.
