Changelog:
- GB core code cleanup completed
- GBA core code cleanup completed
- some more cleanup on missed processor/arm functions/variables
- fixed FC loading icarus bug
- "Load ROM File" icarus functionality restored
- minor code unification efforts all around (not perfect yet)
- MMIO->IO
- mmio.cpp->io.cpp
- read,write->readIO,writeIO
It's been a very long work in progress ... starting all the way back with
v094r09, but the major part of the higan code cleanup is now completed! Of
course, it's very important to note that this is only for the basic style:
- under_score functions and variables are now camelCase
- return-type function-name() are now auto function-name() -> return-type
- Natural<T>/Integer<T> replace (u)intT_n types where possible
- signed/unsigned are now int/uint
- most of the x==true,x==false tests changed to x,!x
A lot of spot improvements to consistency, simplicity and quality have
gone in along the way, of course. But we'll probably never fully finishing
beautifying every last line of code in the entire codebase. Still,
this is a really great start. Going forward, WIP diffs should start
being smaller and of higher quality once again.
I know the joke is, "until my coding style changes again", but ... this
was way too stressful, way too time consuming, and way too risky. I'm
too old and tired now for extreme upheavel like this again. The only
major change I'm slowly mulling over would be renaming the using
Natural<T>/Integer<T> = (u)intT; shorthand to something that isn't as
easily confused with the (u)int_t types ... but we'll see. I'll definitely
continue to change small things all the time, but for the larger picture,
I need to just accept the style I have and live with it.

Changelog:
- fixed Super Game Boy regression from v096r04 with bottom tile row
flickering
- fixed GB STAT IRQ regression from previous WIP
- Altered Space is now playable
- GBVideoPlayer isn't; but nobody seems to know exactly what weird
hardware quirk that one relies on to work
- ~3-4% speed improvement in SuperFX games by eliminating function<>
callback on register assignments
- most noticeable in Doom in-game; least noticeable on Yoshi's Island
title screen (darn)
- finished GSU core and SuperFX coprocessor code cleanups
- did some more work cleaning up the LR35902 core and GB CPU code
Just a fair warning: don't get your hopes up on these GB
fixes. Cliffhanger now hangs completely (har har), and none of the
other bugs are fixed. We pretty much did all this work just for Altered
Space. So, I hope you like playing Altered Space.

Changelog:
- GNUmakefile: reverted $(call unique,) to $(strip)
- processor/r6502: removed templates; reduces object size from 146.5kb
to 107.6kb
- processor/lr35902: removed templates; reduces object size from 386.2kb
to 197.4kb
- processor/spc700: merged op macros for switch table declarations
- sfc/coprocessor/sa1: partial cleanups; flattened directory structure
- sfc/coprocessor/superfx: partial cleanups; flattened directory structure
- sfc/coprocessor/icd2: flattened directory structure
- gb/ppu: changed behavior of STAT IRQs
Major caveat! The GB/GBC STAT IRQ changes has a major bug in it somewhere
that's seriously breaking most games. I'm pushing the WIP anyway, because
I believe the changes to be mostly correct. I'd like to get more people
looking at these changes, and also try more heavy-handed hacking and
diff comparison logging between the previous WIP and this one.

Changelog:
- SFC: balanced profile removed
- SFC: performance profile removed
- SFC: code for handling non-threaded CPU, SMP, DSP, PPU removed
- SFC: Coprocessor, Controller (and expansion port) shared Thread code
merged to SFC::Cothread
- Cothread here just means "Thread with CPU affinity" (couldn't think
of a better name, sorry)
- SFC: CPU now has vector<Thread*> coprocessors, peripherals;
- this is the beginning of work to allow expansion port devices to be
dynamically changed at run-time
- ruby: all audio drivers default to 48000hz instead of 22050hz now if
no frequency is assigned
- note: the WASAPI driver can default to whatever the native frequency
is; doesn't have to be 48000hz
- tomoko: removed the ability to change the frequency from the UI (but
it will display the frequency used)
- tomoko: removed the timing settings panel
- the goal is to work toward smooth video via adaptive sync
- the model is broken by not being in control of the audio frequency
anyway
- it's further broken by PAL running at 50hz and WSC running at 75hz
- it was always broken anyway by SNES interlace timing varying from
progressive timing
- higan: audio/ stub created (for now, it's just nall/dsp/ moved here
and included as a header)
- higan: video/ stub created
- higan/GNUmakefile: now includes build rules for essential components
(libco, emulator, audio, video)
The audio changes are in preparation to merge wareya's awesome WASAPI
work without the need for the nall/dsp resampler.

Changelog:
- fixed DAS instruction (Judgment Silversword score)
- fixed [VH]TMR_FREQ writes (Judgement Silversword audio after area 20)
- fixed initialization of SP (fixes seven games that were hanging on
startup)
- added SER_STATUS and SER_DATA stubs (fixes four games that were
hanging on startup)
- initialized IEEP data (fixes Super Robot Taisen Compact 2 series)
- note: you'll need to delete your internal.com in WonderSwan
(Color).sys folders
- fixed CMPS and SCAS termination condition (fixes serious bugs in four
games)
- set read/writeCompleted flags for EEPROM status (fixes Tetsujin 28
Gou)
- major code cleanups to SFC/R65816 and SFC/CPU
- mostly refactored disassembler to output strings instead of using
char* buffer
- unrolled all the subfolders on sfc/cpu to a single directory
- corrected casing for all of sfc/cpu and a large portion of
processor/r65816
I kind of went overboard on the code cleanup with this WIP. Hopefully
nothing broke. Any testing one can do with the SFC accuracy core would
be greatly appreciated.
There's still an absolutely huge amount of work left to go, but I do
want to eventually refresh the entire codebase to my current coding
style, which is extremely different from stuff that's been in higan
mostly untouched since ~2006 or so. It's dangerous and fickle work, but
if I don't do it, then the code will be a jumbled mess of several
different styles.
byuu says:
I refactored my schedulers. Added about ten lines to each scheduler, and
removed about 100 lines of calling into internal state in the scheduler
for the FC,SFC cores and about 30-40 lines for the other cores. All of
its state is now private.
Also reworked all of the entry points to static auto Enter() and auto
main(). Where Enter() handles all the synchronization stuff, and main()
doesn't need the while(true); loop forcing another layer of indentation
everywhere.
Took a few hours to do, but totally worth it. I'm surprised I didn't do
this sooner.
Also updated icarus gmake install rule to copy over the database.

Changelog:
- restructured the project and removed a whole bunch of old/dead
directives from higan/GNUmakefile
- huge amounts of work on hiro/cocoa (compiles but ~70% of the
functionality is commented out)
- fixed a masking error in my ARM CPU disassembler [Lioncash]
- SFC: decided to change board cic=(411,413) back to board
region=(ntsc,pal) ... the former was too obtuse
If you rename Boolean (it's a problem with an include from ruby, not
from hiro) and disable all the ruby drivers, you can compile an
OS X binary, but obviously it's not going to do anything.
It's a boring WIP, I just wanted to push out the project structure
change now at the start of this WIP cycle.
