Changelog:
- GBA: SOUND_CTL_H is readable, fixes sound effects in Mario&Luigi
Superstar Saga [Cydrak] (note: game is still unplayable due to other
bugs)
- phoenix/Windows: workaround for Win32 API ListView bug, fixes slot
loading behavior
- ruby: added udev driver for Linux with rumble support, and added
rumble support to existing RawInput driver for XInput and DirectInput
- ethos: added new "Rumble" mapping to GBA input assignment, use it to
tell higan which controller to rumble (clear it to disable rumble)
- GBA: Game Boy Player rumble is now fully emulated
- core: added new normalized raw-color palette mode for Display
Emulation shaders
The way rumble was added to ethos was somewhat hackish. The support
doesn't really exist in nall.
I need to redesign the entire input system, but that's not a change
I want to make so close to a release.

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/

- 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 SA-1 MDR; fixes bug in SD Gundam G-Next where the main
battleship was unable to fire
- added out-of-the-box support for any BSD running Clang 3.3+ (FreeBSD
10+, notably)
- added new video shader, "Display Emulation", which changes the shader
based on the emulated system
- fixed the home button to go to your default library path
- phoenix: Windows port won't send onActivate unless an item is selected
(prevents crashing on pressing enter in file dialog)
- ruby: removed vec4 position from out Vertex {} (helps AMD cards)
- shaders: updated all shaders to use texture() instead of texture2D()
(helps AMD cards)
The "Display Emulation" option works like this: when selected, it tries
to load "<path>/Video Shaders/Emulation/<systemName>.shader/"; otherwise
it falls back to the blur shader. <path> is the usual (next to binary,
then in <config>/higan, then in /usr/share/higan, etc); and <systemName>
is "Famicom", "Super Famicom", "Game Boy", "Game Boy Color", "Game Boy
Advance"
To support BSD, I had to modify the $(platform) variable to
differentiate between Linux and BSD.
As such, the new $(platform) values are:
win -> windows
osx -> macosx
x -> linux or bsd
I am also checking uname -s instead of uname -a now. No reason to
potentially match the hostname to the wrong OS type.

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.
byuu describes the changes since v067:
This release officially introduces the accuracy and performance cores,
alongside the previously-existing compatibility core. The accuracy core
allows the most accurate SNES emulation ever seen, with every last
processor running at the lowest possible clock synchronization level.
The performance core allows slower computers the chance to finally use
bsnes. It is capable of attaining 60fps in standard games even on an
entry-level Intel Atom processor, commonly found in netbooks.
The accuracy core is absolutely not meant for casual gaming at all. It
is meant solely for getting as close to 100% perfection as possible, no
matter the cost to speed. It should only be used for testing,
development or debugging.
The compatibility core is identical to bsnes v067 and earlier, but is
now roughly 10% faster. This is the default and recommended core for
casual gaming.
The performance core contains an entirely new S-CPU core, with
range-tested IRQs; and uses blargg's heavily-optimized S-DSP core
directly. Although there are very minor accuracy tradeoffs to increase
speed, I am confident that the performance core is still more accurate
and compatible than any other SNES emulator. The S-CPU, S-SMP, S-DSP,
SuperFX and SA-1 processors are all clock-based, just as in the accuracy
and compatibility cores; and as always, there are zero game-specific
hacks. Its compatibility is still well above 99%, running even the most
challenging games flawlessly.
If you have held off from using bsnes in the past due to its system
requirements, please give the performance core a try. I think you will
be impressed. I'm also not finished: I believe performance can be
increased even further.
I would also strongly suggest Windows Vista and Windows 7 users to take
advantage of the new XAudio2 driver by OV2. Not only does it give you
a performance boost, it also lowers latency and provides better sound by
way of skipping an API emulation layer.
Changelog:
- Split core into three profiles: accuracy, compatibility and
performance
- Accuracy core now takes advantage of variable-bitlength integers (eg
uint24_t)
- Performance core uses a new S-CPU core, written from scratch for speed
- Performance core uses blargg's snes_dsp library for S-DSP emulation
- Binaries are now compiled using GCC 4.5
- Added a workaround in the SA-1 core for a bug in GCC 4.5+
- The clock-based S-PPU renderer has greatly improved OAM emulation;
fixing Winter Gold and Megalomania rendering issues
- Corrected pseudo-hires color math in the clock-based S-PPU renderer;
fixing Super Buster Bros backgrounds
- Fixed a clamping bug in the Cx4 16-bit triangle operation [Jonas
Quinn]; fixing Mega Man X2 "gained weapon" star background effect
- Updated video renderer to properly handle mixed-resolution screens
with interlace enabled; fixing Air Strike Patrol level briefing screen
- Added mightymo's 2010-08-19 cheat code pack
- Windows port: added XAudio2 output support [OV2]
- Source: major code restructuring; virtual base classes for processor
- cores removed, build system heavily modified, etc.

Fixed bsnes launcher on Windows XP
Fixed Windows bsnes launcher internationalization support (emulator can
be in a folder with spaces and Japanese characters, and you can drag
a Japanese file name onto the launcher, and it will load it properly)
Moved fast CPU to use a switch table for MMIO, unfortunately for no
speed gain
Bus::read/write take uint24 parameters for address, luckily no speed
penalty
MMIOAccess gained a handle() function, and hid the mmio[] table. Makes
hooking it cleaner
Added malloc.h header to nall/function.hpp to fix a ridiculous GCC 4.5.0
error
Fixed a fairly large bug in the fast CPU IRQ handler, which fixes
Robocop et al
Forgot to bump revision to .24 in the compiled binaries, too lazy to
recompile or hex edit to change them
Unfortunately, in order to add nice battery usage, I have to add the
sleep calls to the video and audio wait loops. But they don't know
anything about the GUI and its settings, nor do I really want to make
them know about this setting. I do not want to force allow it. Even with
the media timer trick, Sleep(0) makes Vsync+Async fail a lot more
frequently than never sleeping at all. I would rather laptop users
suffer 100% utilization of a single core than for all users to not be
able to get good audio+video sync. Not sure what to do about that, so
I'll probably just remove the battery usage comment from performance
mode for now.
byuu says:
Added missing $4200 IRQ lock, which fixes Chou Aniki on the fast CPU
core, so slower PCs can get their brotherly love on.
Added range-based controller IOBit latching to the fast CPU core, which
enables Super Scope and Justifier support. Uses the priority queue as
well, so there is zero speed-hit. Given the way range-testing works, the
trigger point may vary by 1-2 pixels when firing at the same spot. Not
really a big deal when it avoids a massive speed penalty.
Fixed PAL and interlace-mode HVIRQs at V=0,H<2 on the fast CPU core.
Added the dot-renderer's sprite list update-on-OAM-write functionality
to the scanline-based PPU renderer. Unfortunately it looks like all the
speed gain was already taken from the global dirty flag I was using
before, but this certainly won't hurt speed any, so whatever.
Added #ifdef to stop CoInitialize(0) on non-Windows ports.
Added #ifdefs to stop gradient fade on Windows port. Not going to fuck
over the Linux port aesthetic because of Qt bug #47,326,927. If there's
a way to tell what Qt theme is being used, I can leave it enabled for
XP/Vista themes.
Moved HDMA trigger from 1104 to 1112, and reduced channel overhead from
24 to 16, to better simulate one-cycle DMA->CPU sync.
Code clarity: I've re-added my varint.hpp classes, and am actively using
them in the accuracy cores. So far, I haven't done anything that would
detriment speed, but it is certainly cool. The APU ports exposed by the
CPU and SMP now take uint2 address arguments, the CPU WRAM address
register is a uint17, and the IRQ H/VTIME values are uint10. This
basically allows the source to clearly convey the data sizes, and
eliminates the need to manually mask values when writing to registers or
reading from memory. I'm going to be doing this everywhere, and it will
have a speed impact eventually, because the automation means we can't
skip masks when we know the data is already masked off.
Source: archive contains the launcher code, so that I can look into why
it's crashing on XP tomorrow.
It doesn't look like Circuit USA's flags are going to work too well with
this new CPU core. Still not sure what the hell Robocop vs The
Terminator is doing, I'll read through the mega SNES thread for clues
tomorrow. Speedy Gonzales is definitely broken, as modifying the MDR was
breaking things with my current core. Probably because the new CPU core
doesn't wait for a cycle edge to trigger.
I was thinking that perhaps we could keep some form of cheat codes list
to work as game-specific hacks for the performance core. Keeps the hacks
out of the emulator, but could allow the remaining bugs to be worked
around for people who have no choice but to use the performance core.
