Update to v094r39 release.

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.

Update to v100r14 release.

(Windows: compile with -fpermissive to silence an annoying error. I'll
fix it in the next WIP.)
I completely replaced the time management system in higan and overhauled
the scheduler.
Before, processor threads would have "int64 clock"; and there would
be a 1:1 relationship between two threads. When thread A ran for X
cycles, it'd subtract X * B.Frequency from clock; and when thread B ran
for Y cycles, it'd add Y * A.Frequency from clock. This worked well
and allowed perfect precision; but it doesn't work when you have more
complicated relationships: eg the 68K can sync to the Z80 and PSG; the
Z80 to the 68K and PSG; so the PSG needs two counters.
The new system instead uses a "uint64 clock" variable that represents
time in attoseconds. Every time the scheduler exits, it subtracts
the smallest clock count from all threads, to prevent an overflow
scenario. The only real downside is that rounding errors mean that
roughly every 20 minutes, we have a rounding error of one clock cycle
(one 20,000,000th of a second.) However, this only applies to systems
with multiple oscillators, like the SNES. And when you're in that
situation ... there's no such thing as a perfect oscillator anyway. A
real SNES will be thousands of times less out of spec than 1hz per 20
minutes.
The advantages are pretty immense. First, we obviously can now support
more complex relationships between threads. Second, we can build a
much more abstracted scheduler. All of libco is now abstracted away
completely, which may permit a state-machine / coroutine version of
Thread in the future. We've basically gone from this:
auto SMP::step(uint clocks) -> void {
clock += clocks * (uint64)cpu.frequency;
dsp.clock -= clocks;
if(dsp.clock < 0 && !scheduler.synchronizing()) co_switch(dsp.thread);
if(clock >= 0 && !scheduler.synchronizing()) co_switch(cpu.thread);
}
To this:
auto SMP::step(uint clocks) -> void {
Thread::step(clocks);
synchronize(dsp);
synchronize(cpu);
}
As you can see, we don't have to do multiple clock adjustments anymore.
This is a huge win for the SNES CPU that had to update the SMP, DSP, all
peripherals and all coprocessors. Likewise, we don't have to synchronize
all coprocessors when one runs, now we can just synchronize the active
one to the CPU.
Third, when changing the frequencies of threads (think SGB speed setting
modes, GBC double-speed mode, etc), it no longer causes the "int64
clock" value to be erroneous.
Fourth, this results in a fairly decent speedup, mostly across the
board. Aside from the GBA being mostly a wash (for unknown reasons),
it's about an 8% - 12% speedup in every other emulation core.
Now, all of this said ... this was an unbelievably massive change, so
... you know what that means >_> If anyone can help test all types of
SNES coprocessors, and some other system games, it'd be appreciated.
----
Lastly, we have a bitchin' new about screen. It unfortunately adds
~200KiB onto the binary size, because the PNG->C++ header file
transformation doesn't compress very well, and I want to keep the
original resource files in with the higan archive. I might try some
things to work around this file size increase in the future, but for now
... yeah, slightly larger archive sizes, sorry.
The logo's a bit busted on Windows (the Label control's background
transparency and alignment settings aren't working), but works well on
GTK. I'll have to fix Windows before the next official release. For now,
look on my Twitter feed if you want to see what it's supposed to look
like.
----
EDIT: forgot about ICD2::Enter. It's doing some weird inverse
run-to-save thing that I need to implement support for somehow. So, save
states on the SGB core probably won't work with this WIP.

Changelog:
- higan/video: added support for Emulator::Sprite
- higan/resource: a new system for accessing embedded binary files
inside the emulation cores; holds the sprites
- higan/sfc/superscope,justifier: re-enabled display of crosshairs
- higan/sfc/superscope: fixed turbo toggle (also shows different
crosshair color when in turbo mode)
- higan/sfc/ppu: always outputs at 512x480 resolution now
- causes a slight speed-hit from ~127fps to ~125fps;
- but allows high-resolution 32x32 cursors that look way better;
- also avoids the need to implement sprite scaling logic
Right now, the PPU code to always output at 480-height is a really gross
hack. Don't worry, I'll make that nicer before release.
Also, superscope.cpp and justifier.cpp are built around a 256x240
screen. But since we now have 512x480, we can make the cursor's movement
much smoother by doubling the resolution on both axes. The actual games
won't see any accuracy improvements when firing the light guns, but the
cursors will animate nicer so I think it's still worth it. I'll work on
that before the next release as well.
The current 32x32 cursors are nicer, but we can do better now with full
24-bit color. So feel free to submit alternatives. I'll probably reject
them, but you can always try :D
The sprites don't support alpha blending, just color keying (0x00000000
= transparent; anything else is 0xff......). We can revisit that later
if necessary.
The way I have it designed, the only files that do anything with
Emulator::Sprite at all are the superscope and justifier folders.
I didn't have to add any hooks anywhere else. Rendering the sprite is
a lot cleaner than the old code, too.

Update to v098r03 release.
byuu says:
It took several hours, but I've rebuilt much of the SNES' bus memory
mapping architecture.
The new design unifies the cartridge string-based mapping
("00-3f,80-bf:8000-ffff") and internal bus.map calls. The map() function
now has an accompanying unmap() function, and instead of a fixed 256
callbacks, it'll scan to find the first available slot. unmap() will
free slots up when zero addresses reference a given slot.
The controllers and expansion port are now both entirely dynamic.
Instead of load/unload/power/reset, they only have the constructor
(power/reset/load) and destructor (unload). What this means is you can
now dynamically change even expansion port devices after the system is
loaded.
Note that this is incredibly dangerous and stupid, but ... oh well. The
whole point of this was for 21fx. There's no way to change the expansion
port device prior to loading a game, but if the 21fx isn't active, then
the reset vector hijack won't work. Now you can load a 21fx game, change
the expansion port device, and simply reset the system to active the
device.
The unification of design between controller port devices and expansion
port devices is nice, and overall this results in a reduction of code
(all of the Mapping stuff in Cartridge is gone, replaced with direct bus
mapping.) And there's always the potential to expand this system more in
the future now.
The big missing feature right now is the ability to push/pop mappings.
So if you look at how the 21fx does the reset vector, you might vomit
a little bit. But ... it works.
Also changed exit(0) to _exit(0) in the POSIX version of nall::execute.
[The _exit(0) thing is an attempt to make higan not crash when it tries
to launch icarus and it's not on $PATH. The theory is that higan forks,
then the child tries to exec icarus and fails, so it exits, all the
unique_ptrs clean up their resources and tell the X server to free
things the parent process is still using. Calling _exit() prevents
destructors from running, and seems to prevent the problem. -Ed.]

things to work around this file size increase in the future, but for now
... yeah, slightly larger archive sizes, sorry.
The logo's a bit busted on Windows (the Label control's background
transparency and alignment settings aren't working), but works well on
GTK. I'll have to fix Windows before the next official release. For now,
look on my Twitter feed if you want to see what it's supposed to look
like.

EDIT: forgot about ICD2::Enter. It's doing some weird inverse
run-to-save thing that I need to implement support for somehow. So, save
states on the SGB core probably won't work with this WIP.

Update to v094r39 release.
byuu says:
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.

Update to v079r06 release.
byuu says:
It does add some more code to the CPU::step() function, so performance
probably went down actually, by about 1%. Removing the input.tick() call
didn't compensate as much as I'd hoped.
Hooked up Super Scope and Justifier support. The good news is that the
Justifier alignment doesn't get fucked up anymore when you go
off-screen. Never could fix that in the old version.
The bad news is that it takes a major speed hit for the time being.
I need to figure out how to run the CPU and input threads out of order.
Every time I try, the input gets thrown off by most of a scanline.
Right now, I'm forced to sync constantly to get the latching position
really accurate. But worst case, I can cut the syncs down by skipping
large chunks around the cursor position, +/-40 clock cycles. So it's
only temporarily slow.
Lastly, killed the old Input class, merged Controllers class into it.
I actually like Controllers as a name better, but it doesn't jive with
video/audio/input, so oh well.
