Update to v103r10 release.
byuu says:
Changelog:
- tomoko: video scaling options are now resolutions in the
configuration file, eg "640x480", "960x720", "1280x960"
- tomoko: main window is now always resizable instead of fixed width
(also supports maximizing)
- tomoko: added support for non-integral scaling in windowed mode
- tomoko: made the quick/managed state messaging more consistent
- tomoko: hide "Find Codes ..." button from the cheat editor window if
the cheat database is not present
- tomoko: per-game cheats.bml file now goes into the higan/ subfolder
instead of the root folder
So the way the new video system works is you have the following options
on the video settings panel:
Windowed mode: { Aspect correction, Integral scaling, Adaptive }
Fullscreen mode: { Aspect correction, Integral scaling } (and one day,
hopefully Exclusive will be added here)
Whenever you adjust the overscan masking, or you change any of the
windowed or fullscreen mode settings, or you choose a different video
scale from the main menu, or you load a new game, or you unload a game,
or you rotate the display of an emulated system, the resizeViewport
logic will be invoked. This logic will remember the last option you
chose for video scale, and base the new window size on that value as an
upper limit of the new window size.
If you are in windowed mode and have adaptive enabled, it will shrink
the window to fit the contents of the emulated system's video output.
Otherwise, if you are not in integral scaling mode, it will scale the
video as large as possible to fit into the video scaled size you have
selected. Otherwise, it will perform an integral scale and center the
video inside of the viewport.
If you are in fullscreen mode, it's much the same, only there is no
adaptive mode.
A major problem with Xorg is that it's basically impossible to change
the resizability attribute of a window post-creation. You can do it, but
all kinds of crazy issues start popping up. Like if you toggle
fullscreen, then you'll find that the window won't grow past a certain
fairly small size that it's already at, and cannot be shrunk. And the
multipliers will stop expanding the window as large as they should. And
sometimes the UI elements won't be placed in the correct position, or
the video will draw over them. It's a big mess. So I have to keep the
main window always resizable. Also, note that this is not a limitation
of hiro. It's just totally broken in Xorg itself. No amount of fiddling
has ever allowed this to work reliably for me on either GTK+ 2 or Qt 4.
So what this means is ... the adaptive mode window is also resizable.
What happens here is, whenever you drag the corners of the main window
to resize it, or toggle the maximize window button, higan will bypass
the video scale resizing code and instead act as though the adaptive
scaling mode were disabled. So if integral scaling is checked, it'll
begin scaling in integral mode. Otherwise, it'll begin scaling in
non-integral mode.
And because of this flexibility, it no longer made sense for the video
scale menu to be a radio box. I know, it sucks to not see what the
active selection is anymore, but ... say you set the scale to small,
then you accidentally resized the window a little, but want it snapped
back to the proper small resolution dimensions. If it were a radio item,
you couldn't reselect the same option again, because it's already active
and events don't propagate in said case. By turning them into regular
menu options, the video scale menu can be used to restore window sizing.
Errata:
On Windows, the main window blinks a few times on first load. The fix
for that is a safeguard in the video settings code, roughly like so ...
but note you'd need to make a few other changes for this to work against
v103r10:
auto VideoSettings::updateViewport(bool firstRun) -> void {
settings["Video/Overscan/Horizontal"].setValue(horizontalMaskSlider.position());
settings["Video/Overscan/Vertical"].setValue(verticalMaskSlider.position());
settings["Video/Windowed/AspectCorrection"].setValue(windowedModeAspectCorrection.checked());
settings["Video/Windowed/IntegralScaling"].setValue(windowedModeIntegralScaling.checked());
settings["Video/Windowed/AdaptiveSizing"].setValue(windowedModeAdaptiveSizing.checked());
settings["Video/Fullscreen/AspectCorrection"].setValue(fullscreenModeAspectCorrection.checked());
settings["Video/Fullscreen/IntegralScaling"].setValue(fullscreenModeIntegralScaling.checked());
horizontalMaskValue.setText({horizontalMaskSlider.position()});
verticalMaskValue.setText({verticalMaskSlider.position()});
if(!firstRun) presentation->resizeViewport();
}
That'll get it down to one blink, as with v103 official. Not sure I can
eliminate that one extra blink.
I forgot to remove the setResizable toggle on fullscreen mode exit. On
Windows, the main window will end up unresizable after toggling
fullscreen. I missed that one because like I said, toggling resizability
is totally broken on Xorg. You can fix that with the below change:
auto Presentation::toggleFullScreen() -> void {
if(!fullScreen()) {
menuBar.setVisible(false);
statusBar.setVisible(false);
//setResizable(true);
setFullScreen(true);
if(!input->acquired()) input->acquire();
} else {
if(input->acquired()) input->release();
setFullScreen(false);
//setResizable(false);
menuBar.setVisible(true);
statusBar.setVisible(settings["UserInterface/ShowStatusBar"].boolean());
}
resizeViewport();
}
Windows is stealing focus on calls to resizeViewport(), so we need to
deal with that somehow ...
I'm not really concerned about the behavior of shrinking the viewport
below the smallest multiplier for a given system. It might make sense to
snap it to the window size and forego all other scaling, but honestly
... meh. I don't really care. Nobody sane is going to play like that.

Update to v103r09 release.
byuu says:
Changelog:
- gba/apu: fixed wave RAM nibble ordering (fixes audio in Castlevania,
PocketNES)
- emulator: restructured video information to just a single
videoResolution() → VideoResolution function
- returns "projected size" (between 160x144 and 320x240)
- "internal buffer size" (up to 1280x480)
- returns aspect correction multiplier that is to be applied to
the width field
- the value could be < 1.0 to handle systems with taller
pixels; although higan doesn't emulate such a system
- tomoko: all calculations for scaling and overscan masking are done
by the GUI now
- tomoko: aspect correction can be enabled in either windowed or
fullscreen mode separately; moved to Video settings panel
- tomoko: video scaling multipliers (against 320x240) can now me
modified from the default (2,3,4) via the configuration file
- use this as a really barebones way of supporting high DPI
monitors; although the GUI elements won't scale nicely
- if you set a value less than two, or greater than your
resolution divided by 320x240, it's your own fault when things
blow up. I'm not babysitting anyone with advanced config-file
only options.
- tomoko: added new adaptive windowed mode
- when enabled, the window will shrink to eliminate any black
borders when loading a game or changing video settings. The
window will not reposition itself.
- tomoko: added new adaptive fullscreen mode
- when enabled, the integral scaling will be disabled for
fullscreen mode, forcing the video to fill at least one
direction of the video monitor completely.
I expect we will be bikeshedding for the next month on how to describe
the new video options, where they should appear in the GUI, changes
people want, etc ... but suffice to say, I'm happy with the
functionality, so I don't intend to make changes to -what- things do,
but I will entertain better ways to name things.

Update to v101 release.
byuu says (in the public announcement):
Not a large changelog this time, sorry. This release is mostly to fix
the SA-1 issue, and to get some real-world testing of the new scheduler
model. Most of the work in the past month has gone into writing a 68000
CPU core; yet it's still only about half-way finished.
Changelog (since the previous release):
- fixed SNES SA-1 IRQ regression (fixes Super Mario RPG level-up
screen)
- new scheduler for all emulator cores (precision of 2^-127)
- icarus database adds nine new SNES games
- added Input/Frequency to settings file (allows simulation of
latency)
byuu says (in the WIP forum):
Changelog:
- in 32-bit mode, Thread uses uint64\_t with 2^-63 time units (10^-7
precision in the worst case)
- nearly ten times the precision of an attosecond
- in 64-bit mode, Thread uses uint128\_t with 2^-127 time units
(10^-26 precision in the worst case)
- far more accurate than yoctoseconds; almost closing in on planck
time
Note: a quartz crystal is accurate to 10^-4 or 10^-5. A cesium fountain
atomic clock is accurate to 10^-15. So ... yeah. 2^-63 was perfectly
fine; but there was no speed penalty whatsoever for using uint128\_t in
64-bit mode, so why not?

Update to v100r16 release.
byuu says: (Windows users may need to include <sys/time.h> at the top of nall/chrono.hpp, not sure.) Unchangelog: - forgot to add the Scheduler clock=0 fix because I have the memory of a goldfish Changelog: - new icarus database with nine additional games - hiro(GTK,Qt) won't constantly write its settings.bml file to disk anymore - added latency simulator for fun (settings.bml => Input/Latency in milliseconds) So the last one ... I wanted to test out nall::chrono, and I was also thinking that by polling every emulated frame, it's pretty wasteful when you are using Fast Forward and hitting 200+fps. As I've said before, calls to ruby::input::poll are not cheap. So to get around this, I added a limiter so that if you called the hardware poll function within N milliseconds, it'll return without doing any actual work. And indeed, that increases my framerate of Zelda 3 uncapped from 133fps to 142fps. Yay. But it's not a "real" speedup, as it only helps you when you exceed 100% speed (theoretically, you'd need to crack 300% speed since the game itself will poll at 16ms at 100% speed, but yet it sped up Zelda 3, so who am I to complain?) I threw the latency value into the settings file. It should be 16, but I set it to 5 since that was the lowest before it started negatively impacting uncapped speeds. You're wasting your time and CPU cycles setting it lower than 5, but if people like placebo effects it might work. Maybe I should let it be a signed integer so people can set it to -16 and think it's actually faster :P (I'm only joking. I took out the 96000hz audio placebo effect as well. Not really into psychological tricks anymore.) But yeah seriously, I didn't do this to start this discussion again for the billionth time. Please don't go there. And please don't tell me this WIP has higher/lower latency than before. I don't want to hear it. The only reason I bring it up is for the fun part that is worth discussing: put up or shut up time on how sensitive you are to latency! You can set the value above 5 to see how games feel. I personally can't really tell a difference until about 50. And I can't be 100% confident it's worse until about 75. But ... when I set it to 150, games become "extra difficult" ... the higher it goes, the worse it gets :D For this WIP, I've left no upper limit cap. I'll probably set a cap of something like 500ms or 1000ms for the official release. Need to balance user error/trolling with enjoyability. I'll think about it. [...] Now, what I worry about is stupid people seeing it and thinking it's an "added latency" setting, as if anyone would intentionally make things worse by default. This is a limiter. So if 5ms have passed since the game last polled, and that will be the case 99.9% of the time in games, the next poll will happen just in time, immediately when the game polls the inputs. Thus, a value below 1/<framerate>ms is not only pointless, if you go too low it will ruin your fast forward max speeds. I did say I didn't want to resort to placebo tricks, but I also don't want to spark up public discussion on this again either. So it might be best to default Input/Latency to 0ms, and internally have a max(5, latency) wrapper around the value. |

Update to v098r13 release.
byuu says: Changelog: - nall/dsp returns with new iir/biquad.hpp and resampler/cubic.hpp files - nall/queue.hpp added (simple ring buffer ... nall/vector wouldn't cause too many moves with FIFO) - audio streams now only buffer 20ms; so even if multiple audio streams desync, latency can never exceed 20ms - replaced blackman windwed sinc FIR hermite audio filter with transposed direct form II biquadratic sixth-order IIR butterworth filter (better attenuation of frequencies above 20KHz, faster, no need for decimation, less code) - put in experimental eight-tap echo filter (a lot better than what I had before, but still rather weak) - substantial cleanups to the SuperFX GSU processor core (slightly faster, 479KB->100KB object file, 42.7KB->33.4KB source code size, way less code duplication) We'll definitely want to test the whole SuperFX library (not many games) just to make sure there's no regressions caused by this one. Not sure what I want to do with audio processing effects yet. I've always really wanted lots of fun controls to customize audio, and now finally with this new biquad filter, I can finally start implementing real effects. For instance, an equalizer wouldn't be too complicated anymore. The new reverb effect is still a poor man's version. I need to find human readable source for implementing a comb-filter properly. I'm pretty sure I can already treat nall::queue as an all-pass filter since all that does is phase shift (fancy audio term for "delay audio"). What's really going to be hard is figuring out how to expose user-friendly settings for controlling it. It looks like you need a bunch of coprime coefficients, and I don't think casual users are going to be able to hand-enter coprime values to get the echo effect they want. I uh ... don't even know how to calculate coprime values dynamically right now >_> But we're going to have to, as they are correlated to the output sampling rate. We'll definitely want to make some audio profiles so that users can quickly select pre-configured themes that sound nice, but expose the underlying coefficients so that they can tweak stuff to their liking. This isn't just about higan, this is about me trying to learn digital signal processing, so please don't be too upset about feature creep or anything on this. Anyway ... I'm having some difficulties with my audio right now. When the reverb effect is enabled, there's a bunch of static on system reset for just a moment. But this should not be possible. nall::queue is initializing all previous reverb sample elements to 0.0. I don't understand where static is coming in from. Further, we have the same issue with both the windowed sinc and the biquad filters ... a bit of a popping sound when starting a game. Any help tracking this down would be appreciated. There's also one really annoying issue ... I can't seem to do reverb or volume adjustments with normalized samples. If I say "volume *= 0.5" in higan/audio/audio.cpp line 68, it doesn't just halve the volume, it adds a whole bunch of distortion. This makes absolutely zero sense to me. The sample values are between 0.0 (mute) and 1.0 (full volume) here, so multiplying a double by 0.5 shouldn't cause distortion. So right now, I'm doing these adjustments with less precision after denormalizing back to int16. Anyone ever see something like that? :/ |

Update to v098r06 release.
byuu says:
Changelog:
- emulation cores now refresh video from host thread instead of
cothreads (fix AMD crash)
- SFC: fixed another bug with leap year months in SharpRTC emulation
- SFC: cleaned up camelCase on function names for
armdsp,epsonrtc,hitachidsp,mcc,nss,sharprtc classes
- GB: added MBC1M emulation (requires manually setting mapper=MBC1M in
manifest.bml for now, sorry)
- audio: implemented Emulator::Audio mixer and effects processor
- audio: implemented Emulator::Stream interface
- it is now possible to have more than two audio streams: eg SNES
+ SGB + MSU1 + Voicer-Kun (eventually)
- audio: added reverb delay + reverb level settings; exposed balance
configuration in UI
- video: reworked palette generation to re-enable saturation, gamma,
luminance adjustments
- higan/emulator.cpp is gone since there was nothing left in it
I know you guys are going to say the color adjust/balance/reverb stuff
is pointless. And indeed it mostly is. But I like the idea of allowing
some fun special effects and configurability that isn't system-wide.
Note: there seems to be some kind of added audio lag in the SGB
emulation now, and I don't really understand why. The code should be
effectively identical to what I had before. The only main thing is that
I'm sampling things to 48000hz instead of 32040hz before mixing. There's
no point where I'm intentionally introducing added latency though. I'm
kind of stumped, so if anyone wouldn't mind taking a look at it, it'd be
much appreciated :/
I don't have an MSU1 test ROM, but the latency issue may affect MSU1 as
well, and that would be very bad.

Update to v098r05 release.
byuu says:
Changelog:
- WS/WSC: re-added support for screen rotation (code is inside WS core)
- ruby: changed sample(uint16_t left, uint16_t right) to sample(int16_t
left, int16_t right);
- requires casting to uint prior to shifting in each driver, but
I felt it was misleading to use uint16_t just to avoid that
- ruby: WASAPI is now built in by default; has wareya's improvements,
and now supports latency adjust
- tomoko: audio settings panel has new "Exclusive Mode" checkbox for
WASAPI driver only
- note: although the setting *does* take effect in real-time, I'd
suggest restarting the emulator after changing it
- tomoko: audio latency can now be set to 0ms (which in reality means
"the minimum supported by the driver")
- all: increased cothread size from 512KiB to 2MiB to see if it fixes
bullshit AMD driver crashes
- this appears to cause a slight speed penalty due to cache locality
going down between threads, though

Update to v098r01 release.
byuu says:
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.

Update to v097r02 release.
byuu says:
Note: balanced/performance profiles still broken, sorry.
Changelog:
- added nall/GNUmakefile unique() function; used on linking phase of
higan
- added nall/unique_pointer
- target-tomoko and {System}::Video updated to use
unique_pointer<ClassName> instead of ClassName* [1]
- locate() updated to search multiple paths [2]
- GB: pass gekkio's if_ie_registers and boot_hwio-G test ROMs
- FC, GB, GBA: merge video/ into the PPU cores
- ruby: fixed ~AudioXAudio2() typo
[1] I expected this to cause new crashes on exit due to changing the
order of destruction of objects (and deleting things that weren't
deleted before), but ... so far, so good. I guess we'll see what crops
up, especially on OS X (which is already crashing for unknown reasons on
exit.)
[2] right now, the search paths are: programpath(), {configpath(),
"higan/"}, {localpath(), "higan/"}; but we can add as many more as we
want, and we can also add platform-specific versions.

Update to v097 release.
byuu says: This release features improvements to all emulation cores, but most substantially for the Game Boy core. All of blargg's test ROMs that pass in gambatte now either pass in higan, or are off by 1-2 clocks (the actual behaviors are fully emulated.) I consider the Game Boy core to now be fairly accurate, but there's still more improvements to be had. Also, what's sure to be a major feature for some: higan now has full support for loading and playing ordinary ROM files, whether they have copier headers, weird extensions, or are inside compressed archives. You can load these games from the command-line, from the main Library menu (via Load ROM Image), or via drag-and-drop on the main higan window. Of course, fans of game folders and the library need not worry: that's still there as well. Also new, you can drop the (uncompressed) Game Boy Advance BIOS onto the higan main window to install it into the correct location with the correct file name. Lastly, this release technically restores Mac OS X support. However, it's still not very stable, so I have decided against releasing binaries at this time. I'd rather not rush this and leave a bad first impression for OS X users. Changelog (since v096): - higan: project source code hierarchy restructured; icarus directly integrated - higan: added software emulation of color-bleed, LCD-refresh, scanlines, interlacing - icarus: you can now load and import ROM files/archives from the main higan menu - NES: fixed manifest parsing for board mirroring and VRC pinouts - SNES: fixed manifest for Star Ocean - SNES: fixed manifest for Rockman X2,X3 - GB: enabling LCD restarts frame - GB: emulated extra OAM STAT IRQ quirk required for GBVideoPlayer (Shonumi) - GB: VBK, BGPI, OBPI are readable - GB: OAM DMA happens inside PPU core instead of CPU core - GB: fixed APU length and sweep operations - GB: emulated wave RAM quirks when accessing while channel is enabled - GB: improved timings of several CPU opcodes (gekkio) - GB: improved timings of OAM DMA refresh (gekkio) - GB: CPU uses open collector logic; return 0xFF for unmapped memory (gekkio) - GBA: fixed sequencer enable flags; fixes audio in Zelda - Minish Cap (Jonas Quinn) - GBA: fixed disassembler masking error (Lioncash) - hiro: Cocoa support added; higan can now be compiled on Mac OS X 10.7+ - nall: improved program path detection on Windows - higan/Windows: moved configuration data from %appdata% to %localappdata% - higan/Linux,BSD: moved configuration data from ~/.config/higan to ~/.local/higan |

Update to v096r07 release.
byuu says: Changelog: - configuration files are now stored in localpath() instead of configpath() - Video gamma/saturation/luminance sliders are gone now, sorry - added Video Filter->Blur Emulation [1] - added Video Filter->Scanline Emulation [2] - improvements to GBA audio emulation (fixes Minish Cap) [Jonas Quinn] [1] For the Famicom, this does nothing. For the Super Famicom, this performs horizontal blending for proper pseudo-hires translucency. For the Game Boy, Game Boy Color, and Game Boy Advance, this performs interframe blending (each frame is the average of the current and previous frame), which is important for things like the GBVideoPlayer. [2] Right now, this only applies to the Super Famicom, but it'll come to the Famicom in the future. For the Super Famicom, this option doesn't just add scanlines, it simulates the phosphor decay that's visible in interlace mode. If you observe an interlaced game like RPM Racing on a real SNES, you'll notice that even on perfectly still screens, the image appears to shake. This option emulates that effect. Note 1: the buffering right now is a little sub-optimal, so there will be a slight speed hit with this new support. Since the core is now generating native ARGB8888 colors, it might as well call out to the interface to lock/unlock/refresh the video, that way it can render directly to the screen. Although ... that might not be such a hot idea, since the GBx interframe blending reads from the target buffer, and that tends to be a catastrophic option for performance. Note 2: the balanced and performance profiles for the SNES are completely busted again. This WIP took 6 1/2 hours, and I'm exhausted. Very much not looking forward to working on those, since those two have all kinds of fucked up speedup tricks for non-interlaced and/or non-hires video modes. Note 3: if you're on Windows and you saved your system folders somewhere else, now'd be a good time to move them to %localappdata%/higan |

byuu says: 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. |
