Changelog:
- SNES mid-scanline BGMODE fixes finally merged (can run
atx2.zip{mode7.smc}+mtest(2).sfc properly now)
- Makefile now discards all built-in rules and variables
- switch on bool warning disabled for GCC now as well (was already
disabled for Clang)
- when loading a game, if any required files are missing, display
a warning message box (manifest.bml, program.rom, bios.rom, etc)
- when loading a game (or a game slot), if manifest.bml is missing, it
will invoke icarus to try and generate it
- if that fails (icarus is missing or the folder is bad), you will get
a warning telling you that the manifest can't be loaded
The warning prompt on missing files work for both games and the .sys
folders and their files. For some reason, failing to load the DMG/CGB
BIOS is causing a crash before I can display the modal dialog. I have no
idea why, and the stack frame backtrace is junk.
I also can't seem to abort the failed loading process. If I call
Program::unloadMedia(), I get a nasty segfault. Again with a really
nasty stack trace. So for now, it'll just end up sitting there emulating
an empty ROM (solid black screen.) In time, I'd like to fix that too.
Lastly, I need a better method than popen for Windows. popen is kind of
ugly and flashes a console window for a brief second even if the
application launched is linked with -mwindows. Not sure if there even is
one (I need to read the stdout result, so CreateProcess may not work
unless I do something nasty like "> %tmp%/temp") I'm also using the
regular popen instead of _wpopen, so for this WIP, it won't work if your
game folder has non-English letters in the path.

This updates higan to use the new Markup::Node changes. This is a really
big change, and one slight typo anywhere could break certain classes of
games from playing.
I don't have ananke hooked up again yet, so I don't have the ability to
test this much. If anyone with some v094 game folders wouldn't mind
testing, I'd help out a great deal.
I'm most concerned about testing one of each SNES special chip game.
Most notably, systems like the SA-1, HitachiDSP and NEC-DSP were using
the fancier lookups, eg node["rom[0]/name"], which I had to convert to
a rather ugly node["rom"].at(0)["name"], which I'm fairly confident
won't work. I'm going to blame that on the fumes from the shelves I just
stained >.> Might work with node.find("rom[0]/name")(0) though ...? But
so ugly ... ugh.
That aside, this WIP adds the accuracy-PPU inlining, so the accuracy
profile should run around 7.5% faster than before.

Commands can be prefixed with: (cpu|smp|ppu|dsp|apu|vram|oam|cgram)/ to
set their source. Eg "vram/hex 0800" or "smp/breakpoints.append execute
ffc0"; default is cpu.
These overlap a little bit in odd ways, but that's just the way the SNES
works: it's not a very orthogonal system. CPU is both a processor and
the main bus (ROM, RAM, WRAM, etc), APU is the shared memory by the
SMP+DSP (eg use it to catch writes from either chip); PPU probably won't
ever be used since it's broken down into three separate buses (VRAM,
OAM, CGRAM), but DSP could be useful for tracking bugs like we found in
Koushien 2 with the DSP echo buffer corrupting SMP opcodes. Technically
the PPU memory pools are only ever tripped by the CPU poking at them, as
the PPU doesn't ever write.
I now have run.for, run.to, step.for, step.to. The difference is that
run only prints the next instruction after running, whereas step prints
all of the instructions along the way as well. run.to acts the same as
"step over" here. Although it's not quite as nice, since you have to
specify the address of the next instruction.
Logging the Field/Vcounter/Hcounter on instruction listings now, good
for timing information.
Added in the tracer mask, as well as memory export, as well as
VRAM/OAM/CGRAM/SMP read/write/execute breakpoints, as well as an APU
usage map (it tracks DSP reads/writes separately, although I don't
currently have debugger callbacks on DSP accesses just yet.)
Have not hooked up actual SMP debugging just yet, but I plan to soon.
Still thinking about how I want to allow / block interleaving of
instructions (terminal output and tracing.)
So ... remaining tasks at this point:
- full SMP debugging
- CPU+SMP interleave support
- aliases
- hotkeys
- save states (will be kind of tricky ... will have to suppress
breakpoints during synchronization, or abort a save in a break event.)
- keep track of window geometry between runs

Changelog:

with display enabled
- fixes backgrounds and text in Wacky Races
- Game Boy (Color): fixed underflow in window clamping
- fixes Wacky Races, Prehistorik Man, Alleyway, etc
- Game Boy (Color): LCD OAM DMA was running too slow
- fixes Shin Megami Tensei - Devichil - Kuro no Sho
- Game Boy Advance: removed built-in frame blending; display emulation
shaders will handle this going forward
- Game Boy Advance: added Game Boy Player emulation
- currently the screen is tinted red during rumble, no actual gamepad
rumble support yet
- this is going to be slow, as we have to hash the frame to detect the
GBP logo, it'll be optional later on
- Emulator::Interface::Palette can now output a raw palette (for Display
Emulation shaders only)
- color channels are not yet split up, it's just the raw packed value

Changelog:
- nall: fixed major memory leak in string class
- ruby: video shaders support #define-based settings now
- phoenix/GTK+: support > 256x256 icons for window / task bar / alt-tab
- sfc: remove random/ and config/, merge into system/
- ethos: delete higan.png (48x48), replace with higan512.png (512x512)
as new higan.png
- ethos: default gamma to 100% (no color adjustment)
- ethos: use "Video Shaders/Display Emulation/" instead of "Video
Shaders/Emulation/"
- use g++ instead of g++-4.7 (g++ -v must be >= 4.7)
- use -std=c++11 instead of -std=gnu++11
- applied a few patches from Debian upstream to make their packaging job
easier
So because colors are normalized in GLSL, I won't be able to offer video
shaders absolute color literals. We will have to perform basic color
conversion inside the core.
As such, the current plan is to create some sort of Emulator::Settings
interface. With that, I'll connect an option for color correction, which
will be on by default. For FC/SFC, that will mean gamma correction
(darker / stronger colors), and for GB/GBC/GBA, it will mean simulating
the weird brightness levels of the displays. I am undecided on whether
to use pea soup green for the GB or not. By not doing so, it'll be
easier for the display emulation shader to do it.

Changelog:
- added Cocoa target: higan can now be compiled for OS X Lion
[Cydrak, byuu]
- SNES/accuracy profile hires color blending improvements - fixes
Marvelous text [AWJ]
- fixed a slight bug in SNES/SA-1 VBR support caused by a typo
- added support for multi-pass shaders that can load external textures
(requires OpenGL 3.2+)
- added game library path (used by ananke->Import Game) to
Settings->Advanced
- system profiles, shaders and cheats database can be stored in "all
users" shared folders now (eg /usr/share on Linux)
- all configuration files are in BML format now, instead of XML (much
easier to read and edit this way)
- main window supports drag-and-drop of game folders (but not game files
/ ZIP archives)
- audio buffer clears when entering a modal loop on Windows (prevents
audio repetition with DirectSound driver)
- a substantial amount of code clean-up (probably the biggest
refactoring to date)
One highly desired target for this release was to default to the optimal
drivers instead of the safest drivers, but because AMD drivers don't
seem to like my OpenGL 3.2 driver, I've decided to postpone that. AMD
has too big a market share. Hopefully with v093 officially released, we
can get some public input on what AMD doesn't like.
