Update to 20180724 release.
byuu says: I failed to complete a WIP, have five of eight cores updated with some major changes to Emulator::Interface. I'll just post a quick temporary WIP in the off chance someone wants to look over the new interface and comment on it. Also implemented screen saver suppression into hiro/GTK. I should also add ... a plan of mine is to develop target-bsnes into a more generic user interface, with the general idea being that target-higan is for multiple Emulator::Interface cores at the same time, and target-bsnes is for just one Emulator::Interface core. The idea being that if one were to compile target-bsnes with the GBA core, it'd become bgba, for instance. I don't plan on releasing single-core emulators like this, but ... I don't see any downsides to being more flexible. |

Changelog:
- emulator/video,audio: various cleanups
- emulator/audio: removed reverb effect (it breaks very badly on
high-frequency systems)
- emulator/audio: the Nyquist anti-aliasing lowpass filter is now
generated automatically instead of set per-core
- at 44.1KHz output, it's set to 22KHz; at 48KHz, it's set to
22KHz; at 96KHz, it's set to 25KHz
- this filter now takes the bsnes emulation speed setting into
account
- all system/video.cpp files removed; inlined in System::power() and
Interface::set() instead
- sfc/cpu: pre-compute `HTIME` as `HTIME+1<<2` for faster comparisons of
HIRQs
- sfc/cpu: re-add check to block IRQs on the last dot of each frame
(minor speed hit)
- hiro/gtk3: fixed headers for Linux compilation finally
- hiro/gtk,qt: fixed settings.cpp logic so initial values are used
when no settings.bml file exists
- hiro/gtk: started a minor experiment to specify theming information
in settings.bml files
- nall/dsp: allow the precision type (double) to be overridden (to
float)
- nall: add some helpers for generating pre-compiled headers
- it was a failure to try using them for higan, however ...
- nall: add some helpers for reading fallback values from empty
`Markup::Node[search]` statements
Todo:
- CRITICAL: a lot of my IRQ/NMI/HDMA timing tests are failing with the
fast PPU ... need to figure out why
- space between Emulator::video functions and Emulator::audio
functions in gb/system/system.cpp
- remove Audio/Reverb/Enable from settings.bml in target-bsnes

Update to v106r47 release.

This is probably the largest code-change diff I've done in years.
I spent four days working 10-16 hours a day reworking layouts in hiro
completely.
The result is we now have TableLayout, which will allow for better
horizontal+vertical combined alignment.
Windows, GTK2, and now GTK3 are fully supported.
Windows is getting the initial window geometry wrong by a bit.
GTK2 and GTK3 work perfectly. I basically abandoned trying to detect
resize signals, and instead keep a list of all hiro windows that are
allocated, and every time the main loop runs, it will query all of them
to see if they've been resized. I'm disgusted that I have to do this,
but after fighting with GTK for years, I'm about sick of it. GTK was
doing this crazy thing where it would trigger another size-allocate
inside of a previous size-allocate, and so my layouts would be halfway
through resizing all the widgets, and then the size-allocate would kick
off another one. That would end up leaving the rest of the first layout
loop with bad widget sizes. And if I detected a second re-entry and
blocked it, then the entire window would end up with the older geometry.
I started trying to build a message queue system to allow the second
layout resize to occur after the first one completed, but this was just
too much madness, so I went with the simpler solution.
Qt4 has some geometry problems, and doesn't show tab frame layouts
properly yet.
Qt5 causes an ICE error and tanks my entire Xorg display server, so ...
something is seriously wrong there, and it's not hiro's fault. Creating
a dummy Qt5 application without even using hiro, just int main() {
TestObject object; } with object performing a dynamic\_cast to a derived
type segfaults. Memory is getting corrupted where GCC allocates the
vtables for classes, just by linking in Qt. Could be somehow related to
the -fPIC requirement that only Qt5 has ... could just be that FreeBSD
10.1 has a buggy implementation of Qt5. I don't know. It's beyond my
ability to debug, so this one's going to stay broken.
The Cocoa port is busted. I'll fix it up to compile again, but that's
about all I'm going to do.
Many optimizations mean bsnes and higan open faster. GTK2 and GTK3 both
resize windows very quickly now.
higan crashes when you load a game, so that's not good. bsnes works
though.
bsnes also has the start of a localization engine now. Still a long way
to go.
The makefiles received a rather substantial restructuring. Including the
ruby and hiro makefiles will add the necessary compilation rules for
you, which also means that moc will run for the qt4 and qt5 targets, and
windres will run for the Windows targets.

Update to v102r22 release.
byuu says:
Changelog:
- higan: Emulator::Interface::videoSize() renamed to videoResolution()
- higan: Emulator::Interface::rtcsync() renamed to rtcSynchronize()
- higan: added video display rotation support to Video
- GBA: substantially improved audio mixing
- fixed bug with FIFO 50%/100% volume setting
- now properly using SOUNDBIAS amplitude to control output
frequencies
- reduced quantization noise
- corrected relative volumes between PSG and FIFO channels
- both PSG and FIFO values cached based on amplitude; resulting in
cleaner PCM samples
- treating PSG volume=3 as 200% volume instead of 0% volume now
(unverified: to match mGBA)
- GBA: properly initialize ALL CPU state; including the vital
prefetch.wait=1 (fixes Classic NES series games)
- GBA: added video rotation with automatic key translation support
- PCE: reduced output resolution scalar from 285x242 to 285x240
- the extra two scanlines won't be visible on most TVs; and they
make all other cores look worse
- this is because all other cores output at 240p or less; so they
were all receiving black bars in windowed mode
- tomoko: added "Rotate Display" hotkey setting
- tomoko: changed hotkey multi-key logic to OR instead of AND
- left support for flipping it back inside the core; for those so
inclined; by uncommenting one line in input.hpp
- tomoko: when choosing Settings→Configuration, it will
automatically select the currently loaded system
- for instance, if you're playing a Game Gear game, it'll take you
to the Game Gear input settings
- if no games are loaded, it will take you to the hotkeys panel
instead
- WS(C): merged "Hardware-Vertical", "Hardware-Horizontal" controls
into combined "Hardware"
- WS(C): converted rotation support from being inside the core to
using Emulator::Video
- this lets WS(C) video content scale larger now that it's not
bounded by a 224x224 square box
- WS(C): added automatic key rotation support
- WS(C): removed emulator "Rotate" key (use the general hotkey
instead; I recommend F8 for this)
- nall: added serializer support for nall::Boolean (boolean) types
- although I will probably prefer the usage of uint1 in most cases

Update to v101r31 release.
byuu says:
Changelog:
- converted Emulator::Interface::Bind to Emulator::Platform
- temporarily disabled SGB hooks
- SMS: emulated Game Gear palette (latching word-write behavior not
implemented yet)
- SMS: emulated Master System 'Reset' button, Game Gear 'Start' button
- SMS: removed reset() functionality, driven by the mappable input now
instead
- SMS: split interface class in two: one for Master System, one for
Game Gear
- SMS: emulated Game Gear video cropping to 160x144
- PCE: started on HuC6280 CPU core—so far only registers, NOP
instruction has been implemented
Errata:
- Super Game Boy support is broken and thus disabled
- if you switch between Master System and Game Gear without
restarting, bad things happen:
- SMS→GG, no video output on the GG
- GG→SMS, no input on the SMS
I'm not sure what's causing the SMS\<-\>GG switch bug, having a hard
time debugging it. Help would be very much appreciated, if anyone's up
for it. Otherwise I'll keep trying to track it down on my end.

Update to v098r12 release.
byuu says: 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 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 v098r04 release.
byuu says: Changelog: - SFC: fixed behavior of 21fx $21fe register when no device is connected (must return zero) - SFC: reduced 21fx buffer size to 1024 bytes in both directions to mirror the FT232H we are using - SFC: eliminated dsp/modulo-array.hpp [1] - higan: implemented higan/video interface and migrated all cores to it [2] [1] the echo history buffer was 8-bytes, so there was no need for it at all here. Not sure what I was thinking. The BRR buffer was 12-bytes, and has very weird behavior ... but there's only a single location in the code where it actually writes to this buffer. It's much easier to just write to the buffer three times there instead of implementing an entire class just to abstract away two lines of code. This change actually boosted the speed from ~124.5fps to around ~127.5fps, but that's within the margin of error for GCC. I doubt it's actually faster this way. The DSP core could really use a ton of work. It comes from a port of blargg's spc_dsp to my coding style, but he was extremely fond of using 32-bit signed integers everywhere. There's a lot of opportunity to remove red tape masking by resizing the variables to their actual state sizes. I really need to find where I put spc_dsp6.sfc from blargg. It's a great test to verify if I've made any mistakes in my implementation that would cause regressions. Don't suppose anyone has it? [2] so again, the idea is that higan/audio and higan/video are going to sit between the emulation cores and the user interfaces. The hope is to output raw encoding data from the emulation cores without having to worry about the video display format (generally 24-bit RGB) of the host display. And also to avoid having to repeat myself with eg three separate implementations of interframe blending, and so on. Furthermore, the idea is that the user interface can configure its side of the settings, and the emulation cores can configure their sides. Thus, neither has to worry about the other end. And now we can spin off new user interfaces much easier without having to mess with all of these things. Right now, I've implemented color emulation, interframe blending and SNES horizontal color bleed. I did not implement scanlines (and interlace effects for them) yet, but I probably will at some point. Further, for right now, the WonderSwan/Color screen rotation is busted and will only show games in the horizontal orientation. Obviously this must be fixed before the next official release, but I'll want to think about how to implement it. Also, the SNES light gun pointers are missing for now. Things are a bit messy right now as I've gone through several revisions of how to handle these things, so a good house cleaning is in order once everything is feature-complete again. I need to sit down and think through how and where I want to handle things like light gun cursors, LCD icons, and maybe even rasterized text messages. And obviously ... higan/audio is still just nall::DSP's headers. I need to revamp that whole interface. I want to make it quite powerful with a true audio mixer so I can handle things like SNES+SGB+MSU1+Voicer-Kun+SNES-CD (five separate audio streams at once.) The video system has the concept of "effects" for things like color bleed and interframe blending. I want to extend on this with useful other effects, such as NTSC simulation, maybe bringing back my mini-HQ2x filter, etc. I'd also like to restore the saturation/gamma/luma adjustment sliders ... I always liked allowing people to compensate for their displays without having to change settings system-wide. Lastly, I've always wanted to see some audio effects. Although I doubt we'll ever get my dream of CoreAudio-style profiles, I'd like to get some basic equalizer settings and echo/reverb effects in there. |

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.
