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.

Nothing WS-related this time.
First, I fixed expansion port device mapping. On first load, it was
mapping the expansion port device too late, so it ended up not taking
effect. I had to spin out the logic for that into
Program::connectDevices(). This was proving to be quite annoying while
testing eBoot (SNES-Hook simulation.)
Second, I fixed the audio->set(Frequency, Latency) functions to take
(uint) parameters from the configuration file, so the weird behavior
around changing settings in the audio panel should hopefully be gone
now.
Third, I rewrote the interface->load,unload functions to call into the
(Emulator)::System::load,unload functions. And I have those call out to
Cartridge::load,unload. Before, this was inverted, and Cartridge::load()
was invoking System::load(), which I felt was kind of backward.
The Super Game Boy really didn't like this change, however. And it took
me a few hours to power through it. Before, I had the Game Boy core
dummying out all the interface->(load,save)Request calls, and having the
SNES core make them for it. This is because the folder paths and IDs
will be different between the two cores.
I've redesigned things so that ICD2's Emulator::Interface overloads
loadRequest and saveRequest, and translates the requests into new
requests for the SuperFamicom core. This allows the Game Boy code to do
its own loading for everything without a bunch of Super Game Boy special
casing, and without any awkwardness around powering on with no cartridge
inserted.
This also lets the SNES side of things simply call into higher-level
GameBoy::interface->load,save(id, stream) functions instead of stabbing
at the raw underlying state inside of various Game Boy core emulation
classes. So things are a lot better abstracted now.

This moves toward a profile-selection mode. Right now, it is incomplete.
There are three binaries, one for each profile. The GUI selection
doesn't actually do anything yet. There will be a launcher in a future
release that loads each profile's respective binary.
I reverted away from blargg's SMP library for the time being, in favor
of my own. This will fix most of the csnes/bsnes-performance bugs. This
causes a 10% speed hit on 64-bit platforms, and a 15% speed hit on
32-bit platforms. I hope to be able to regain that speed in the future,
I may also experiment with creating my own fast-SMP core which drops bus
hold delays and TEST register support (never used by anything, ever.)
Save states now work in all three cores, but they are not
cross-compatible. The profile name is stored in the description field of
the save states, and it won't load a state if the profile name doesn't
match.
The debugger only works on the research target for now. Give it time and
it will return for the other targets.
Other than that, let's please resume testing on all three once again.
See how far we get this time :)
I can confirm the following games have issues on the performance
profile:
- Armored Police Metal Jacket (minor logo flickering, not a big deal)
- Chou Aniki (won't start, so obviously unplayable)
- Robocop vs The Terminator (major in-game flickering, unplayable)
Anyone still have that gigantic bsnes thread archive from the ZSNES
forum? Maybe I posted about how to fix those two broken games in there,
heh.
I really want to release this as v1.0, but my better judgment says we
need to give it another week. Damn.

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.

Changelog:
- GBA: lots of emulation improvements
- PPU PRAM is 16-bits wide
- DMA masks &~1/Half, &~3/Word
- VRAM OBJ 8-bit writes are ignored
- OAM 8-bit writes are ignored
- BGnCNT unused bits are writable*
- BG(0,1)CNT can't set the d13
- BLDALPHA is readable (fixes Donkey Kong Country, etc)
- SNES: lots of code cleanups
- sfc/chip => sfc/coprocessor
- UI: save most recent controller selection
GBA test scores: 1552/1552, 37/38, 1020/1260
(* forgot to add the value to the read function, so endrift's I/O tests
for them will fail. Fixed locally.)
Note: SNES is the only system with multiple controller/expansion port
options, and as such is the only one with a "None" option. Because it's
shared by the controller and expansion port, it ends up sorted first in
the list. This means that on your first run, you'll need to go to Super
Famicom->Controller Port 1 and select "Gamepad", otherwise input won't
work.
Also note that changing the expansion port device requires loading a new
cart. Unlike controllers, you aren't meant to hotplug expansion port
devices.

As a result of the changes, old mappings will no longer work. The above
XML example will run Super Mario World 2: Yoshi's Island. Otherwise,
you'll have to write your own.
All that's left now is to work some sort of database mapping system in,
so I can start dumping carts en masse.
The NES changes that FitzRoy asked for are mostly in as well.
Also, part of the reason I haven't released a WIP ... but fuck it, I'm
not going to wait forever to post a new WIP.
I've added a skeleton driver to emulate Campus Challenge '92 and
Powerfest '94. There's no actual emulation, except for the stuff I can
glean from looking at the pictures of the board. It has a DSP-1 (so
SR/DR registers), four ROMs that map in and out, RAM, etc.
I've also added preliminary mapping to upload high scores to a website,
but obviously I need the ROMs first.

- Makefile now discards all built-in rules and variables
- switch on bool warning disabled for GCC now as well (was already

- 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 v092 release.
In the release thread, byuu says:
The first official release of higan has been posted. higan is the
new name for bsnes, and it continues with the latter's version
numbering.
Note that as of now, bsnes still exists. It's a module distributed
inside of higan. bsnes is now specific to my SNES emulator.
Due to last minute changes to the emulator interface, and missing
support in ananke, I wasn't able to include Cydrak's Nintendo DS
emulator dasShiny in this build, but I hope to do so in the next
release.

For both new and experienced users, please read the higan user guide
first:

In the v091 WIP thread, byuu says:
r15->r16:
- BS-X MaskROM handling (partial ... need to split bsx/flash away
from sfc/chip, restructure code - it requires tagging the base
cart markup for now, but it needs to parse the slotted cart
markup)
- phoenixflags / phoenixlink += -m32
- nall/sort stability
- if(input.poll(scancode[activeScancode]) == false) return;
- MSU1 / USART need to use interface->path(1)
- MSU1 needs to use Markup::Document, not XML::Document
- case-insensitive folder listings
- remove nall/emulation/system.hpp files (move to ananke)
- remove rom/ram id= checks with indexing
X have cores ask for manifest.bml (skipped for v092's release, too
big a change)
- rename compatibility profile to balanced (so people don't assume
it has better compatibility than accuracy)

First, I fixed expansion port device mapping. On first load, it was
mapping the expansion port device too late, so it ended up not taking
effect. I had to spin out the logic for that into
Program::connectDevices(). This was proving to be quite annoying while
testing eBoot (SNES-Hook simulation.)
Second, I fixed the audio->set(Frequency, Latency) functions to take
(uint) parameters from the configuration file, so the weird behavior
around changing settings in the audio panel should hopefully be gone
now.
Third, I rewrote the interface->load,unload functions to call into the
(Emulator)::System::load,unload functions. And I have those call out to
Cartridge::load,unload. Before, this was inverted, and Cartridge::load()
was invoking System::load(), which I felt was kind of backward.
The Super Game Boy really didn't like this change, however. And it took
me a few hours to power through it. Before, I had the Game Boy core
dummying out all the interface->(load,save)Request calls, and having the
SNES core make them for it. This is because the folder paths and IDs
will be different between the two cores.
I've redesigned things so that ICD2's Emulator::Interface overloads
loadRequest and saveRequest, and translates the requests into new
requests for the SuperFamicom core. This allows the Game Boy code to do
its own loading for everything without a bunch of Super Game Boy special
casing, and without any awkwardness around powering on with no cartridge
inserted.
This also lets the SNES side of things simply call into higher-level
GameBoy::interface->load,save(id, stream) functions instead of stabbing

Update to v074r10 release.
byuu says:
Major WIP, countless changes. I really went to town on cleaning up the
source today with all kinds of new ideas. I'll post the ones I remember,
use diff -ru to get the rest.
What I like the most is my new within template:
template<unsigned lo, unsigned hi>
alwaysinline bool within(unsigned addr) {
static const unsigned mask = ~(hi ^ lo);
return (addr & mask) == lo;
}
Before, you would see code like this:
if((addr & 0xe0e000) == 0x206000) { //$20-3f:6000-7fff
The comment is basically necessary, and you have to trust that the mask
is right, or do the math yourself.
Now, it looks like this:
if(within<0x20, 0x3f, 0x6000, 0x7fff>(addr)) {
That's the same as within<0x206000, 0x3f7fff>, I just made an
SNES-variant to more closely simulate my XML mapping style:
20-3f:6000-7fff.
Now obviously this has limitations, it only works in base-2 and it can't
manage some tricky edge cases like (addr & 0x408000) == 0x008000 for
00-3f|80-bf:8000-ffff. But for the most part, I'll be using this where
I can. The Game Boy is fully ported over to it (via the MBCs), but the
SNES only has the BS-X town cartridge moved over so far. SuperFX and
SA-1 at the very least could benefit.
Next up, since the memory map is now static, there's really no reason to
remap the entire thing at power-on and reset. So it is now set up at
cartridge load and that's it. I moved the CPU/PPU/WRAM mapping out of
memory.cpp and into their respective processors. A bit of duplication
only because there are multiple processor cores for the different
profiles, but I'm not worried about that. This is also going to be
necessary to fix the debugger.
Next, Coprocessor::enable() actually does what I initially intended it
to now: it is called once to turn a chip on after cartridge load. It's
not called on power cycle anymore. This should help fix power-cycle on
my serial simulation code, and was needed to map the bus exactly one
time. Although most stuff is mapped through XML, some chips still need
some manual hooks for monitoring and such (eg S-DD1.)
Next, I've started killing off memory::, it was initially an
over-reaction to the question of where to put APURAM (in the SMP or
DSP?). The idea was to have this namespace that contained all memory for
everything. But it was very annoying and tedious, and various chips
ignored the convention anyway like ST-0011 RAM, which couldn't work
anyway since it is natively uint16 and not uint8. Cx4 will need 24-bit
RAM eventually, too. There's 8->24-bit functions in there now, because
the HLE code is hideous.
So far, all the cartridge.cpp memory:: types have been destroyed.
memory::cartrom, memory::cartram become cartridge.rom and cartridge.ram.
memory::cartrtc was moved into the SRTC and SPC7110 classes directly.
memory::bsxflash was moved into BSXFlash. memory::bsxram and
memory::bsxpram were moved into BSXCartridge (the town cartridge).
memory::st[AB](rom|ram) were moved into a new area,
snes/chip/sufamiturbo. The snes/chip moniker really doesn't work so
well, since it also has base units, and the serial communications stuff
which is through the controller port, but oh well, now it also has the
base structure for the Sufami Turbo cartridge too. So now we have
sufamiturbo.slotA.rom, sufamiturbo.slotB.ram, etc.
Next, the ST-0010/ST-0011 actually save the data RAM to disk. This
wasn't at all compatible with my old system, and I didn't want to keep
adding memory types to check inside the main UI cartridge RAM loading
and saving routines.
So I built a NonVolatileRAM vector inside SNES::Cartridge, and any chip
that has memory it wants to save and load from disk can append onto it
: data, size, id ("srm", "rtc", "nec", etc) and slot (0 = cartridge,
1 = slot A, 2 = slot B)
To load and save memory, we just do a simple: foreach(memory,
SNES::cartridge.nvram) load/saveMemory(memory).
As a result, you can now keep your save games in F1 Race of Champions II
and Hayazashi Nidan Morita Shougi. Technically I think Metal Combat
should work this way as well, having the RAM being part of the chip
itself, but for now that chip just writes directly into cartridge.ram,
so it also technically saves to disk for now.
To avoid a potential conflict with a manipulated memory map, BS-X SRAM
and PSRAM are now .bss and .bsp, and not .srm and .psr. Honestly I don't
like .srm as an extension either, but it doesn't bother me enough to
break save RAM compatibility with other emulators, so don't worry about
that changing.
I finally killed off MappedRAM initializing size to ~0 (-1U). A size of
zero means there is no memory there just the same. This was an old
holdover for handling MMIO mapping, if I recall correctly. Something
about a size of zero on MMIO-Memory objects causing it to wrap the
address, so ~0 would let it map direct addresses ... or something.
Whatever, that's not needed at all anymore.
BSXBase becomes BSXSatellaview, and I've defaulted the device to being
attached since it won't affect non-BSX games anyway. Eventually the GUI
needs to make that an option. BSXCart becomes BSXCartridge. BSXFlash
remains unchanged.
I probably need to make Coprocessor::disable() functions now to free up
memory on unload, but it shouldn't hurt anything the way it is.
libsnes is most definitely broken to all hell and back now, and the
debugger is still shot. I suppose we'll need some tricky code to work
with the old ID system, and we'll need to add some more IDs for the new
memory types.

- VRAM OBJ 8-bit writes are ignored
- OAM 8-bit writes are ignored

GBA test scores: 1552/1552, 37/38, 1020/1260
(* forgot to add the value to the read function, so endrift's I/O tests
for them will fail. Fixed locally.)
Note: SNES is the only system with multiple controller/expansion port
options, and as such is the only one with a "None" option. Because it's
shared by the controller and expansion port, it ends up sorted first in
the list. This means that on your first run, you'll need to go to Super
Famicom->Controller Port 1 and select "Gamepad", otherwise input won't
work.
Also note that changing the expansion port device requires loading a new
cart. Unlike controllers, you aren't meant to hotplug expansion port
devices.

- completely rewrote memory sub-system to support 1-byte granularity in
XML mapping
- removed Memory inheritance and MMIO class completely, any address can
be mapped to any function now
- SuperFX: removed SuperFXBus : Bus, now implemented manually
- SA-1: removed SA1Bus : Bus, now implemented manually
- entire bus mapping is now static, happens once on cartridge load
- as a result, read/write handlers now handle MMC mapping; slower
average case, far faster worst case
- namespace memory is no more, RAM arrays are stored inside the chips
they are owned by now
- GameBoy: improved CPU HALT emulation, fixes Zelda: Link's Awakening
scrolling
- GameBoy: added serial emulation (cannot connect to another GB yet),
fixes Shin Megami Tensei - Devichil
- GameBoy: improved LCD STAT emulation, fixes Sagaia
- ui: added fullscreen support (F11 key), video settings allows for
three scale settings
- ui: fixed brightness, contrast, gamma, audio volume, input frequency
values on program startup
- ui: since Qt is dead, config file becomes bsnes.cfg once again
- Super Game Boy: you can now load the BIOS without a game inserted to
see a pretty white box
- ui-gameboy: can be built without SNES components now
- libsnes: now a UI target, compile with 'make ui=ui-libsnes'
- libsnes: added WRAM, APURAM, VRAM, OAM, CGRAM access (cheat search,
etc)
- source: removed launcher/, as the Qt port is now gone
- source: Makefile restructuring to better support new ui targets
- source: lots of other internal code cleanup work

auto System::unload() -> void {

Update to v097r12 release.
byuu says:
Nothing WS-related this time.
First, I fixed expansion port device mapping. On first load, it was
mapping the expansion port device too late, so it ended up not taking
effect. I had to spin out the logic for that into
Program::connectDevices(). This was proving to be quite annoying while
testing eBoot (SNES-Hook simulation.)
Second, I fixed the audio->set(Frequency, Latency) functions to take
(uint) parameters from the configuration file, so the weird behavior
around changing settings in the audio panel should hopefully be gone
now.
Third, I rewrote the interface->load,unload functions to call into the
(Emulator)::System::load,unload functions. And I have those call out to
Cartridge::load,unload. Before, this was inverted, and Cartridge::load()
was invoking System::load(), which I felt was kind of backward.
The Super Game Boy really didn't like this change, however. And it took
me a few hours to power through it. Before, I had the Game Boy core
dummying out all the interface->(load,save)Request calls, and having the
SNES core make them for it. This is because the folder paths and IDs
will be different between the two cores.
I've redesigned things so that ICD2's Emulator::Interface overloads
loadRequest and saveRequest, and translates the requests into new
requests for the SuperFamicom core. This allows the Game Boy code to do
its own loading for everything without a bunch of Super Game Boy special
casing, and without any awkwardness around powering on with no cartridge
inserted.
This also lets the SNES side of things simply call into higher-level
GameBoy::interface->load,save(id, stream) functions instead of stabbing
at the raw underlying state inside of various Game Boy core emulation
classes. So things are a lot better abstracted now.

for them will fail. Fixed locally.)
Note: SNES is the only system with multiple controller/expansion port
options, and as such is the only one with a "None" option. Because it's
shared by the controller and expansion port, it ends up sorted first in
the list. This means that on your first run, you'll need to go to Super
Famicom->Controller Port 1 and select "Gamepad", otherwise input won't
work.
Also note that changing the expansion port device requires loading a new
cart. Unlike controllers, you aren't meant to hotplug expansion port
devices.

Update to v074r10 release.
byuu says:
Major WIP, countless changes. I really went to town on cleaning up the
source today with all kinds of new ideas. I'll post the ones I remember,
use diff -ru to get the rest.
What I like the most is my new within template:
template<unsigned lo, unsigned hi>
alwaysinline bool within(unsigned addr) {
static const unsigned mask = ~(hi ^ lo);
return (addr & mask) == lo;
}
Before, you would see code like this:
if((addr & 0xe0e000) == 0x206000) { //$20-3f:6000-7fff
The comment is basically necessary, and you have to trust that the mask
is right, or do the math yourself.
Now, it looks like this:
if(within<0x20, 0x3f, 0x6000, 0x7fff>(addr)) {
That's the same as within<0x206000, 0x3f7fff>, I just made an
SNES-variant to more closely simulate my XML mapping style:
20-3f:6000-7fff.
Now obviously this has limitations, it only works in base-2 and it can't
manage some tricky edge cases like (addr & 0x408000) == 0x008000 for
00-3f|80-bf:8000-ffff. But for the most part, I'll be using this where
I can. The Game Boy is fully ported over to it (via the MBCs), but the
SNES only has the BS-X town cartridge moved over so far. SuperFX and
SA-1 at the very least could benefit.
Next up, since the memory map is now static, there's really no reason to
remap the entire thing at power-on and reset. So it is now set up at
cartridge load and that's it. I moved the CPU/PPU/WRAM mapping out of
memory.cpp and into their respective processors. A bit of duplication
only because there are multiple processor cores for the different
profiles, but I'm not worried about that. This is also going to be
necessary to fix the debugger.
Next, Coprocessor::enable() actually does what I initially intended it
to now: it is called once to turn a chip on after cartridge load. It's
not called on power cycle anymore. This should help fix power-cycle on
my serial simulation code, and was needed to map the bus exactly one
time. Although most stuff is mapped through XML, some chips still need
some manual hooks for monitoring and such (eg S-DD1.)
Next, I've started killing off memory::, it was initially an
over-reaction to the question of where to put APURAM (in the SMP or
DSP?). The idea was to have this namespace that contained all memory for
everything. But it was very annoying and tedious, and various chips
ignored the convention anyway like ST-0011 RAM, which couldn't work
anyway since it is natively uint16 and not uint8. Cx4 will need 24-bit
RAM eventually, too. There's 8->24-bit functions in there now, because
the HLE code is hideous.
So far, all the cartridge.cpp memory:: types have been destroyed.
memory::cartrom, memory::cartram become cartridge.rom and cartridge.ram.
memory::cartrtc was moved into the SRTC and SPC7110 classes directly.
memory::bsxflash was moved into BSXFlash. memory::bsxram and
memory::bsxpram were moved into BSXCartridge (the town cartridge).
memory::st[AB](rom|ram) were moved into a new area,
snes/chip/sufamiturbo. The snes/chip moniker really doesn't work so
well, since it also has base units, and the serial communications stuff
which is through the controller port, but oh well, now it also has the
base structure for the Sufami Turbo cartridge too. So now we have
sufamiturbo.slotA.rom, sufamiturbo.slotB.ram, etc.
Next, the ST-0010/ST-0011 actually save the data RAM to disk. This
wasn't at all compatible with my old system, and I didn't want to keep
adding memory types to check inside the main UI cartridge RAM loading
and saving routines.
So I built a NonVolatileRAM vector inside SNES::Cartridge, and any chip
that has memory it wants to save and load from disk can append onto it
: data, size, id ("srm", "rtc", "nec", etc) and slot (0 = cartridge,
1 = slot A, 2 = slot B)
To load and save memory, we just do a simple: foreach(memory,
SNES::cartridge.nvram) load/saveMemory(memory).
As a result, you can now keep your save games in F1 Race of Champions II
and Hayazashi Nidan Morita Shougi. Technically I think Metal Combat
should work this way as well, having the RAM being part of the chip
itself, but for now that chip just writes directly into cartridge.ram,
so it also technically saves to disk for now.
To avoid a potential conflict with a manipulated memory map, BS-X SRAM
and PSRAM are now .bss and .bsp, and not .srm and .psr. Honestly I don't
like .srm as an extension either, but it doesn't bother me enough to
break save RAM compatibility with other emulators, so don't worry about
that changing.
I finally killed off MappedRAM initializing size to ~0 (-1U). A size of
zero means there is no memory there just the same. This was an old
holdover for handling MMIO mapping, if I recall correctly. Something
about a size of zero on MMIO-Memory objects causing it to wrap the
address, so ~0 would let it map direct addresses ... or something.
Whatever, that's not needed at all anymore.
BSXBase becomes BSXSatellaview, and I've defaulted the device to being
attached since it won't affect non-BSX games anyway. Eventually the GUI
needs to make that an option. BSXCart becomes BSXCartridge. BSXFlash
remains unchanged.
I probably need to make Coprocessor::disable() functions now to free up
memory on unload, but it shouldn't hurt anything the way it is.
libsnes is most definitely broken to all hell and back now, and the
debugger is still shot. I suppose we'll need some tricky code to work
with the old ID system, and we'll need to add some more IDs for the new
memory types.

Update to v084r03 release.
(r02 was not posted to the WIP thread)
byuu says:
Internally, all color is processed with 30-bit precision. The filters
also operate at 30-bit depth.
There's a new config file setting, video.depth, which defaults to 24.
This causes the final output to downsample to 24-bit, as most will
require.
If you set it to 30-bit, the downsampling will not occur, and bsnes will
ask ruby for a 30-bit surface. If you don't have one available, you're
going to get bad colors. Or maybe even a crash with OpenGL.
I don't yet have detection code to make sure you have an appropriate
visual in place.
30-bit mode will really only work if you are running Linux, running Xorg
at Depth 30, use the OpenGL or XShm driver, have an nVidia Quadro or AMD
FireGL card with the official drivers, and have a 30-bit capable
monitor.
Lots of planning and work for very little gain here, but it's nice that
it's finally finished.
Oh, I had to change the contrast/brightness formulas a tiny bit, but
they still work and look nice.
