GTK+3 is designed for automatic layout, where widgets are automatically sized
and positioned according to the size of their contents. However, hiro has to be
compatible with Windows, which lacks an automatic layout system, so hiro apps
tend to position widgets manually.
Unfortunately, the GTK+3 default theme uses much bigger widgets than GTK+2 or
Windows, so hiro apps using the GTK+3 backend tend to have ugly, overlapping
widgets. To make GTK+3 behave more like other hiro targets, we add custom CSS
and override the default theme at runtime.
Fixes#168.
On X11, hiro uses the xdg-screensaver helper tool to disable the screensaver,
which detects the screensaver that is running and uses the appropriate
mechanism to communicate with it. The tool's API expects an X11 window ID,
but at least some screensavers ignore it, so it can be set up however. The
GNOME backend *does* care about the window ID, but its expectations are not
documented anywhere, so byuu spent a frustrating few days trying things
at random to get it working, and failing.
It turns out, GNOME does *not* require the window to be mapped, but it *does*
require the window to have a name. Using XStoreName() to name the window fixes
screensaver suspension for me under GNOME 3.38.
Note: while XStoreName is technically deprecated, it's not going to go away
while X11 is still around, and the reason it's deprecated is because it doesn't
include character encoding data. We don't care — no user should ever see the
window name, and it's plain ASCII so it should be fine.
Fixes#102.

Don't let the point release fool you, there are many significant changes in this
release. I will be keeping bsnes releases using a point system until the new
higan release is ready.
Changelog:
- GUI: added high DPI support
- GUI: fixed the state manager image preview
- Windows: added a new waveOut driver with support for dynamic rate control
- Windows: corrected the XAudio 2.1 dynamic rate control support [BearOso]
- Windows: corrected the Direct3D 9.0 fullscreen exclusive window centering
- Windows: fixed XInput controller support on Windows 10
- SFC: added high-level emulation for the DSP1, DSP2, DSP4, ST010, and Cx4
coprocessors
- SFC: fixed a slight rendering glitch in the intro to Megalomania
If the coprocessor firmware is missing, bsnes will fallback on HLE where it is
supported, which is everything other than SD Gundam GX and the two Hayazashi
Nidan Morita Shougi games.
The Windows dynamic rate control works best with Direct3D in fullscreen
exclusive mode. I recommend the waveOut driver over the XAudio 2.1 driver, as it
is not possible to target a single XAudio2 version on all Windows OS releases.
The waveOut driver should work everywhere out of the box.
Note that with DRC, the synchronization source is your monitor, so you will
want to be running at 60hz (NTSC) or 50hz (PAL). If you have an adaptive sync
monitor, you should instead use the WASAPI (exclusive) or ASIO audio driver.
byuu says:
The biggest change was improving WonderSwan emulation. With help from
trap15, I tracked down a bug where I was checking the wrong bit for
reverse DMA transfers. Then I also emulated VTOTAL to support variable
refresh rate. Then I improved HyperVoice emulation which should be
unsigned samples in three of four modes. That got Fire Lancer running
great. I also rewrote the disassembler. The old one disassembled many
instructions completely wrong, and deviated too much from any known x86
syntax. I also emulated some of the quirks of the V30 (two-byte POP into
registers fails, SALC is just XLAT mirrored, etc) which probably don't
matter unless someone tries to run code to verify it's a NEC CPU and not
an Intel CPU, but hey, why not?
I also put more work into the MSX skeleton, but it's still just a
skeleton with no real emulation yet.
byuu says:
Changelog:
- fixed bug in Emulator::Game::Memory::operator bool()
- nall: renamed view<string> back to `string_view`
- nall:: implemented `array_view`
- Game Boy: split cartridge-specific input mappings (rumble,
accelerometer) to their own separate ports
- Game Boy: fixed MBC7 accelerometer x-axis

- higan: connect Video::poll(),update() functionality
- hiro, ruby: several compilation / bugfixes, should get the macOS
port compiling again, hopefully [Sintendo]
- ruby/video/xshm: fix crashing bug on window resize
- a bit hacky; it's throwing BadAccess Xlib warnings, but they're
not fatal, so I am catching and ignoring them
- bsnes: removed Application::Windows::onModalChange hook that's no
longer needed [Screwtape]
byuu says:
The main thing I worked on today was emulating the MBC7 EEPROM.
And... I have many things to say about that, but not here, and not now...
The missing EEPROM support is why the accelerometer was broken. Although
it's not evidently clear that I'm emulating the actual values
incorrectly. I'll think about it and get it fixed, though.
bsnes went from ~308fps to ~328fps, and I don't even know why. Probably
something somewhere in the 140KB of changes to other things made in this
WIP.
byuu says:
The Windows port can now run the emulation while navigating menus,
moving windows, and resizing windows. The main window also doesn't try
so hard to constantly clear itself. This may leave a bit of unwelcome
residue behind in some video drivers during resize, but under most
drivers, it lets you resize without a huge amount of flickering.
On all platforms, I now also run the emulation during MessageWindow
modal events, where I didn't before.
I'm thinking we should probably mute the audio during modal periods,
since it can generate a good deal of distortion.
The tooltip timeout was increased to ten seconds.
On Windows, the enter key can now activate buttons, so you can more
quickly dismiss MessageDialog windows. This part may not actually work
... I'm in the middle of trying to get messages out of the global
`Application_windowProc` hook and into the individual `Widget_windowProc`
hooks, so I need to do some testing.
I fixed a bug where changing the input driver wouldn't immediately
reload the input/hotkey settings lists properly.
I also went from disabling the driver "Change" button when the currently
active driver is selected in the list, to instead setting it to say
"Reload", and I also added a tool tip to the input driver reload button,
advising that if you're using DirectInput or SDL, you can hit "Reload"
to rescan for hotplugged gamepads without needing to restart the
emulator. XInput and udev have auto hotswap support. If we can ever get
that into DirectInput and SDL, then I'll remove the tooltip. But
regardless, the reload functionality is nice to have for all drivers.
I'm not sure what should happen when a user changes their driver
selection while a game is loaded, gets the warning dialog, chooses not
to change it, and then closes the emulator. Currently, it will make the
change happen the next time you start the emulator. This feels a bit
unexpected, but when you change the selection without a game loaded, it
takes immediate effect. So I'm not really sure what's best here.
byuu says:
I've added tool tips to hiro for Windows, GTK, and Qt. I'm unsure how to
add them for Cocoa. I wasted am embarrassing ~14 hours implementing tool
tips from scratch on Windows, because the `TOOLTIPS_CLASS` widget just
absolutely refused to show up, no matter what I tried. As such, they're
not quite 100% native, but I would really appreciate any patch
submissions to help improve my implementation.
I added tool tips to all of the confusing settings in bsnes. And of
course, for those of you who don't like them, there's a configuration
file setting to turn them off globally.
I also improved Mega Drive handling of the Game Genie a bit, and
restructured the way the Settings class works in bsnes.
Starting now, I'm feature-freezing bsnes and higan. From this point
forward:
- polishing up and fixing bugs caused by the ruby/hiro changes
- adding DRC to XAudio2, and maybe exclusive mode to WGL
- correcting FEoEZ (English) to load and work again out of the box
Once that's done, a final beta of bsnes will go out, I'll fix any
reported bugs that I'm able to, and then v107 should be ready. This time
with higan being functional, but marked as v107 beta. v108 will restore
higan to production status again, alongside bsnes.
byuu says:
I fixed all outstanding bugs that I'm aware of, including all of the
errata I listed yesterday.
And now it's time for lots of regression testing.
After that, I need to add Talarubi's XAudio2 DRC code, and then get a
new public bsnes WIP out for final testing.
New errata: when setting an icon (nall::image) larger than a Canvas on
Windows, it's not centering the image, so you end up seeing the overscan
area in the state manager previews, and the bottom of the image gets cut
off. I also need to forcefully disable the Xlib screensaver disable
support. I think I'll remove the GUI option to bypass it as well, and
just force screensaver disable always on with Windows. I'll improve it
in the future to toggle the effect between emulator pauses.
byuu says:
Everything *should* be working again, but of course that won't
actually be the case. Here's where things stand:
- bsnes, higan, icarus, and genius compile and run fine on FreeBSD
with GTK
- ruby video and audio drivers are untested on Windows, macOS, and
Linux
- hiro is untested on macOS
- bsnes' status bar is not showing up properly with hiro/qt
- bsnes and higan's about screen is not showing up properly with
hiro/qt (1x1 window size)
- bsnes on Windows crashes often when saving states, and I'm not sure
why ... it happens inside Encode::RLE
- bsnes on Windows crashes with ruby.input.windows (unsure why)
- bsnes on Windows fails to show the verified emblem on the status bar
properly
- hiro on Windows flickers when changing tabs
To build the Windows bsnes and higan ports, use
ruby="video.gdi audio.directsound"
Compilation error logs for Linux will help me fix the inevitable list of
typos there. I can fix the typos on other platforms, I just haven't
gotten to it yet.
byuu says:
Changes to hiro will break all but the GTK target. Not that it matters
much given that the only ruby drivers that function are all on BSD
anyway.
But if you are fortunate enough to be able to run this ... you'll find
lots of polishing improvements to the bsnes GUI. I posted some
screenshots on Twitter, if anyone were interested.
byuu says:
Okay, so the WIPs-within-WIPs thing wasn't achieving its desired effect,
and it ended up causing me to have to redo some work on hiro since my
last local snapshot was of r52. So, heck it. I'll just do mostly
non-functional WIPs for a bit, and worry about the fallout years later
when I'm trying to find an emulation regression and cursing that the
WIPs aren't compiling.
I ported all of the ruby input drivers to the new syntax, as well as the
OpenAL driver. If you patch the ruby drivers for Linux with this in
mind, bsnes should compile and run there again.
Also, the bsnes program icon has returned, now that the new hiro layout
code is mature enough and I can simply add and remove the icon as a
Canvas instead of having to try and render into a viewport. The icon
shows up instantly with the main window.
byuu says:
I've completed moving all the class objects from `unique_pointer<T>` to
just T. The one exception is the Emulator::Interface instance. I can
absolutely make that a global object, but only in bsnes where there's
just the one emulation core.
I also moved all the SettingsWindow and ToolsWindow panels out to their
own global objects, and fixed a very difficult bug with GTK TabFrame
controls.
The configuration settings panel is now the emulator settings panel. And
I added some spacing between bold label sections on both the emulator
and driver settings panels.
I gave fixing ComboButtonItem my best shot, given I can't reproduce the
crash. Probably won't work, though.
Also made a very slight consistency improvement to ruby and renamed
driverName() to driver().
...
An important change ... as a result of moving bsnes to global objects,
this means that the constructors for all windows run before the
presentation window is displayed. Before this change, only the
presentation window was constructed first berore displaying it, followed
by the construction of the rest of the GUI windows.
The upside to this is that as soon as you see the main window, the GUI
is ready to go without a period where it's unresponsive.
The downside to this is it takes about 1.5 seconds to show the main
window, compared to around 0.75 seconds before.
I've no intention of changing that back. So if the startup time becomes
a problem, then we'll just have to work on optimizing hiro, so that it
can construct all the global Window objects quicker. The main way to do
that would be to not do calls to the Layout::setGeometry functions for
every widget added, and instead wait until the window is displayed. But
I don't have an easy way to do that, because you want the widget
geometry values to be sane even before the window is visible to help
size certain things.

Sigh ...
asio.hpp needs #include <nall/windows/registry.hpp>
[Since the last WIP, byuu also posted the following message. -Ed.]
ruby drivers have all been updated (but not tested outside of BSD), and
I redesigned the settings window. The driver functionality all exists on
a new "Drivers" panel, the emulator/hack settings go to a
"Configuration" panel, and the video/audio panels lose driver settings.
As does the settings menu and its synchronize options.
I want to start pushing toward a v107 release. Critically, I will need
DirectSound and ALSA to support dynamic rate control. I'd also like to
eliminate the other system manifest.bml files. I need to update the
cheat code database format, and bundle at least a few quark shaders --
although I still need to default to Direct3D on Windows.
Turbo keys would be nice, if it's not too much effort. Aside from
netplay, it's the last significant feature I'm missing.
I think for v107, higan is going to be a bit rough around the edges
compared to bsnes. And I don't think it's practical to finish the bsnes
localization support.
I'm thinking we probably want another WIP to iron out any critical
issues, but this time there should be a feature freeze with the next
WIP.
byuu says:
Sigh, I seem to be spiraling a bit here ... but the work is very
important. Hopefully I can get a solid WIP together soon. But for now...
I've integrated dynamic rate control into ruby::Audio via
setDynamic(bool) for now. It's very demanding, as you would expect. When
it's not in use, I realized the OSS driver's performance was pretty bad
due to calling write() for every sample for every channel. I implemented
a tiny 256-sample buffer and bsnes went from 290fps to 330fps on my
FreeBSD desktop. It may be possible to do the same buffering with DRC,
but for now, I'm not doing so, and adjusting the audio input frequency
on every sample.
I also added ruby::Video::setFlush(bool), which is available only in the
OpenGL drivers, and this causes glFinish() to be called after swapping
display buffers. I really couldn't think of a good name for this, "hard
GPU sync" sounds kind of silly. In my view, flush is what commits queued
events. Eg fflush(). OpenGL of course treats glFlush differently (I
really don't even know what the point of it is even after reading the
manual ...), and then has glFinish ... meh, whatever. It's
setFlush(bool) until I come up with something better. Also as expected,
this one's a big hit to performance.
To implement the DRC, I started putting helper functions into the ruby
video/audio/input core classes. And then the XVideo driver started
crashing. It took hours and hours and hours to track down the problem:
you have to clear XSetWindowAttributes to zero before calling
XCreateWindow. No amount of `--sync`, `gdb break gdk_x_error`, `-Og`,
etc will make Xlib be even remotely helpful in debugging errors like
this.
The GLX, GLX2, and XVideo drivers basically worked by chance before. If
the stack frame had the right memory cleared, it worked. Otherwise it'd
crash with BadValue, and my changing things broke that condition on the
XVideo driver. So this has been fixed in all three now.
Once XVideo was running again, I realized that non-power of two video
sizes were completely broken for the YUV formats. It took a while, but I
managed to fix all of that as well.
At this point, most of ruby is going to be broken outside of FreeBSD, as
I still need to finish updating all the drivers.
byuu says:
I stand corrected, I managed to create and even larger diff than ever.
This one weighs in at 309KiB `>__>`
I'll have to create a changelog later, I'm too tired right now to go
through all of that.
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.

byuu says:
The problems with the Windows and Qt4 ports have all been resolved,
although there's a fairly gross hack on a few Qt widgets to not destruct
once Application::quit() is called to avoid a double free crash (I'm
unsure where Qt is destructing the widgets internally.) The Cocoa port
compiles again at least, though it's bound to have endless problems. I
improved the Label painting in the GTK ports, which fixes the background
color on labels inside TabFrame widgets.
I've optimized the Makefile system even further.
I added a "redo state" command to bsnes, which is created whenever you
load the undo state. There are also hotkeys for both now, although I
don't think they're really something you want to map hotkeys to.
I moved the nall::Locale object inside hiro::Application, so that it can
be used to translate the BrowserDialog and MessageDialog window strings.
I improved the Super Game Boy emulation of `MLT_REQ`, fixing Pokemon
Yellow's custom border and probably more stuff.
Lots of other small fixes and improvements. Things are finally stable
once again after the harrowing layout redesign catastrophe.
Errata:
- ICD::joypID should be set to 3 on reset(). joypWrite() may as well
take uint1 instead of bool.
- hiro/Qt: remove pWindow::setMaximumSize() comment; found a
workaround for it
- nall/GNUmakefile: don't set object.path if it's already set (allow
overrides before including the file)
byuu says:
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.

Changelog:
- nall: merged Path::config() and Path::local() to Path::userData()
- ~/.local/share or %appdata or ~/Library/ApplicationSupport
- higan, bsnes: render main window icon onto viewport instead of
canvas
- should hopefully fix a brief flickering glitch that appears on
Windows
- icarus: improved Super Famicom heuristics for Starfox / Starwing RAM
- ruby/Direct3D: handle viewport size changes in lock() instead of
output()
- fixes icon disappearing when resizing main window
- hiro/Windows: remove WS_DISABLED from StatusBar to fix window
resize grip
- this is experimental: I initially used WS_DISABLED to work
around a focus bug
- yet trying things now, said bug seems(?) to have gone away at
some point ...
- bsnes: added advanced settings panel with real-time driver change
support
I'd like feedback on the real-time driver change, for possible
consideration into adding this to higan as well.
Some drivers just crash, it's a fact of life. The ASIO driver in
particular likes to crash inside the driver itself, without any error
messages ever returned to try and catch.
When you try to change a driver with a game loaded, it gives you a scary
warning, asking if you want to proceed.
When you change a driver, it sets a crash flag, and if the driver
crashes while initializing, then restarting bsnes will disable the
errant driver. If it fails in a recoverable way, then it sets the driver
to “None” and warns you that the driver cannot be used.
What I'm thinking of further adding is to call emulator→save() to
write out the save RAM contents beforehand (although the periodic
auto-saving RAM will handle this anyway when it's enabled), and possibly
it might be wise to capture an emulator save state, although those can't
be taken without advancing the emulator to the next frame, so that might
not be a good idea.
I'm also thinking we should show some kind of message somewhere when a
driver is set to “None”. The status bar can be hidden, so perhaps on the
title bar? Or maybe just a warning on startup that a driver is set to
“None”.

processor(identifier=SDD1)
- higan: when selecting a default game to load for a new system entry,
it will change the system option to match the media type
- higan: the load text box on the system entry window is now editable;
can be used to erase entries
- icarus: fixed bug in Famicom importing
- icarus: importing unappended SNES coprocessor firmware will now
rename the firmware properly
- hiro/GTK,Qt: WM_CLASS is now set correctly in `argv[0]`, so
applications should show “higan”, “icarus” instead of “hiro” now
Note: if you wish to run the BS-X town cartridge, the database currently
lists the download RAM as type “PSRAM”. This needs to be changed to
“RAM” in order to load properly. Otherwise, the emulator will bomb
out on the load window, because BSC-1A5B9P-01 expects PSRAM to always be
present, but it won't find it with the wrong memory type. I'll correct
this in the database in a later release. For now, you can copy the game
portion of the manifest to a new manifest.bml file and drop it into the
gamepak folder until I fix the database.

Changelog:
- main menu renamed again (Library→System→Systems)
- the 'Hidden' checkbox on system properties was moved to the main
list as a 'Show' checkbox instead
- the move up/move down buttons on the systems panel now function
- added icons to indicate 'system' versus 'game boot' entries in the
systems list
I still didn't add ComboEdit to the Windows hiro port, so once again
this will be Linux/BSD only.
I polished the browse button for selecting a boot game. It'll use a list
of all bootable media file extensions, so that if you double-click any
supported game, it'll select it instead of going inside the folder. If
you pick a non-bootable folder, like say a Sufami Turbo cartridge, it
will go inside the folder instead, because it will treat it like any
other regular folder.
Having a checkbox next to text in the same cell doesn't work so well on
lists that have an onActivate action. Say you tried to double-click the
“Name” field on the Systems tab, it would toggle the checkbox twice
before popping open the system properties editor window. So because of
this, I made the show checkbox its own column. And for consistency, I
did the same for the slot# on the cheat editor window.
As a bit of really pedantic polish: if there are no systems enabled,
then the main menu won't show the separator before the “Load ROM Image”
option anymore.
I think something is wrong with the Markup::Node::insert syntax, but I
realized I have Markup::Node::swap, and just used that for the up/down
arrows on the systems panel for now. But we should probably fix insert()
at some point ... sigh.

Changelog:
- Super Game Boy: fixed loading of boot ROM
- hiro: added ComboEdit::setEditable(bool = true);
- tomoko: added new systems settings panel
Note!!: this release will not compile on Windows or macOS due to the
missing ComboEdit control! I'll try to merge in hex's implementation
for the Windows release here soon. macOS users will probably be out of
luck for a while, sorry.
The new systems panel is an idea I've been meaning to implement for
quite a while, but finally got around to starting on it. It's still
fairly unpolished, but the basic idea is there for Linux/BSD users to
try out now.
So imagine the Super Game Boy, BS-X Satellaview, Sufami Turbo, and the
associated BS Memory Pack-slotted SNES cartridges. To play any of those,
you needed to choose Nintendo→Super Famicom, and then select the
relevant cartridge, and then select any slotted cartridges to play with
it.
This was acceptable-ish, if not ideal. But now imagine in the future if
we wanted to support the Famicom Disk System, which is technically a
cartridge that plugs into the Famicom deck. Or the PC Engine CD, which
has one of three special HuCards that must be inserted (ignoring the
Turbo Duo where it's built-in—I'm going to be emulating the Super CD
as if you're using a stock PCE CD.) Or the Mega CD, where there are
probably a half dozen or more BIOS + hardware revisions that are
region-specific, which connect to an expansion port that is identical to
the cartridge port save for the Mega Drive seeing an I/O register bit
toggled here.
In all of these cases, it's going to be a real pain to have to choose
the 'BIOS' every time you want to play a game for them.
I can't distribute these BIOSes with higan due to copyright
restrictions, and trying to ship dummy folders for every possible
combination would become quite odious, and difficult for people to use
(compare to setting up the Game Boy Advance system BIOS.)
And so I've created the new systems settings panel. Here, you can manage
a list of systems that show up under the higan library menu (now renamed
to “System”), where each entry contains name, boot, and hidden
parameters.
The name parameter is what shows up in the system menu. You can call any
system higan emulates whatever you like here. Don't like “Super
Famicom”? Change it to “SNES”, then.
The boot parameter is a combo edit with a dropdown for all of the
systems higan emulates. If you choose one of these, then the higan
system menu option will work exactly like in previous releases, and
prompt you for a cartridge. But if you choose the browse button next to
the combo edit control, you'll get to pick any gamepak from the higan
library of your choosing.
So you could choose the SGB2 BIOS, and name the menu option “Super Game
Boy 2”, and when you choose the menu option, it will load the SFC core,
load the SGB2 BIOS, and only prompt you for the Game Boy game you wish
to play on it. The same deal goes for the FDS, PCE-CD, Mega CD, Mega
Drive Sonic & Knuckles lock-on cartridge, BS-X Satellaview, SD Gundam
G-Next, etc. Whatever you want to be in the menu, you can put in there
by pointing higan at the appropriate 'BIOS' gamepak to load.
Astute readers have probably already noticed, but you can technically
use this on non-slotted games as well, thus creating instant boot
options for your absolute favorite games, if you so wanted. Point it at
Zelda 3, and you can boot it instantly from the main menu, without any
need for file selection.
The hidden option is a way to hide the system entries from the system
menu. Primarily this would be a fast way for users to disable emulation
cores they never use in higan, without having to remove the options.
The major concession with this change is the collapsing of the
per-manufacturer submenus. What this means is you will now have all
twelve higan emulated systems in the main menu by default. This makes
the list rather long, but ... oh well. I may try to offer some form of
grouping in the future, but the grouping defeats the “list order =
display order” design, and I'm not willing to auto-sort the list. I want
people to be able to control the ordering of the system menu, and have
added (as yet non-functional) sorting arrows for that purpose. I also
don't have a combined tree+table view widget in higan to try to and
group things. But ... we'll see how things go in the future.
Another idea is to add a specialty load option that opens up the user's
Emulation library path, and lets you pick a gamepak for any system,
which would boot the same way as when you drop a gamepak onto the higan
executable or main window. So say you almost never play Wonderswan
games, this would be a way to play them without them cluttering your
system menu list.
The “import ROM files” option has been removed. All it does is launch
icarus directly. I would rather users become familiar with using icarus.
The “load ROM file” option remains.
Anyway, this is all still a work in progress, so please give it time and
don't overload me with too many suggested changes right now, thanks :3

My intention is to remove Emulator::Interface::sha256(), as it's not
really useful. They'll be removed from save states as well. I never
bothered validating the SHA256 within them, because that'd be really
annoying for ROM hackers.
I also intend to rename Emulator::Interface::title() to label() instead.
Most everything is still broken. The SNES still needs all the board
definitions updated, all the other cores need to move to using
Emulator::Game.

Changelog:
- nall/GNUmakefile: build=release changed to -O2, build=optimize is
now -O3
- hiro: added Monitor::dpi(uint index) → Position [returns logical
DPI for x, y]
- Position is a bad name, but dpi(monitor).(x,y)() make more sense
than .(width,height)()
- hiro: Position, Size, Geometry, Font changed from using signed int
to float
- hiro: Alignment changed from using double to float
- hiro: added skeleton (unused) Application::scale(), setScale()
functions
Errata:
- hiro/cocoa's Monitor::dpi() is untested. Probably will cause issues
with macOS' automatic scaling.
- hiro/gtk lacks a way to get both per-monitor and per-axis (x,y) DPI
scaling
- hiro/qt lacks a way to get per-monitor DPI scaling (Qt 5.x has this,
but I still use Qt 4.x)
- and just to get global DPI, hiro/qt's DPI retrieval has to use
undocumented functions ... fun
The goal with this WIP was basically to prepare hiro for potential
automatic scaling. It'll be extremely difficult, but I'm convinced that
it must be possible if macOS can do it.
By moving from signed integers to floats for coordinates, we can now
scale and unscale without losing precision. That of course isn't the
hard part, though. The hard part is where and how to do the scaling. In
the ideal application, hiro/core and hiro/extension will handle 100% of
this, and the per-platform hiro/(cocoa,gtk,qt,windows) will not be aware
of what's going on, but ... to even make that possible, things will need
to change in every per-platform core, eg the per-platform code will have
to call a core function to change geometry, which will know about the
scaling and unscale the values back down again.
Gonna be a lot of work, but ... it's a start.

- only took eight months! :D
¹: When I tried to move the Master System hardware port below the
controller ports, I ran into a world of pain.
The input settings list expects every item in the
`InputEmulator<InputPort<InputDevice<InputMapping>>>>` arrays to be
populated with valid results. But these would be sparsely populated
based on the port and device IDs from inside higan. And that is done so
that the Interface::inputPoll can have O(1) lookup of ports and devices.
This worked because all the port and device IDs were sequential (they
left no gaps in the maps upon creating the lists.)
Unfortunately by changing the expectation of port ID to how it appears
in the list, inputs would not poll correctly. By leaving them alone and
just moving Hardware to the third position, the Game Gear would be
missing port IDs of 0 and 1 (the controller ports of the Master System).
Even by trying to make separate MasterSystemHardware and
GameGearHardware ports, things still fractured when the devices were no
longer contigious.
I got pretty sick of this and just decided to give up on O(1)
port/device lookup, and moved to O(n) lookup. It only knocked the
framerate down by maybe one frame per second, enough to be in the margin
of error. Inputs aren't polled *that* often for loops that usually
terminate after 1-2 cycles to be too detrimental to performance.
So the new input system now allows non-sequential port and device IDs.
Remember that I killed input IDs a while back. There's never any reason
for those to need IDs ... it was easier to just order the inputs in the
order you want to see them in the user interface. So the input lookup is
still O(1). Only now, everything's safer and I return a
maybe<InputMapping&>, and won't crash out the program trying to use a
mapping that isn't found for some reason.
Errata: the escape key isn't working on the browser/message dialogs on
Windows, because of course nothing can ever just be easy and work for
me. If anyone else wouldn't mind looking into that, I'd greatly
appreciate it.
Having the `WM_KEYDOWN` test inside the main `Application_sharedProc`, it
seems to not respond to the escape key on modal dialogs. If I put the
`WM_KEYDOWN` test in the main window proc, then it doesn't seem to get
called for `VK_ESCAPE` at all, and doesn't get called period for modal
windows. So I'm at a loss and it's past 4AM here >_>

Changelog:
- added \~130 new PAL games to icarus (courtesy of Smarthuman
and aquaman)
- added all three Korean-localized games to icarus
- sfc: removed SuperDisc emulation (it was going nowhere)
- sfc: fixed MSU1 regression where the play/repeat flags were not

- minor shims to fix compilation issues due to nall changes
The real magic is that we now have 25-30% of the PAL SNES library in
icarus!
Signing will be tricky. Obviously if I put the public key inside the
higan archive, then all anyone has to do is change that public key for
their own releases. And if you download from my site (which is now over
HTTPS), then you don't need the signing to verify integrity. I may just
put the public key on my site on my site and leave it at that, we'll
see.
byuu says:
I reworked the video sizing code. Ended up wasting five fucking hours
fighting GTK. When you call `gtk_widget_set_size_request`, it doesn't
actually happen then. This is kind of a big deal because when I then go
to draw onto the viewport, the actual viewport child window is still the
old size, so the image gets distorted. It recovers in a frame or so with
emulation, but if we were to put a still image on there, it would stay
distorted.
The first thought is, `while(gtk_events_pending())
gtk_main_iteration_do(false);` right after the `set_size_request`. But
nope, it tells you there's no events pending. So then you think, go
deeper, use `XPending()` instead. Same thing, GTK hasn't actually issued
the command to Xlib yet. So then you think, if the widget is realized,
just call a blocking `gtk_main_iteration`. One call does nothing, two
calls results in a deadlock on the second one ... do it before program
startup, and the main window will never appear. Great.
Oh, and it's not just the viewport. It's also the widget container area
of the windows, as well as the window itself, as well as the fullscreen
mode toggle effect. They all do this.
For the latter three, I couldn't find anything that worked, so I just
added 20ms loops of constantly calling `gtk_main_iteration_do(false)`
after each one of those things. The downside here is toggling the status
bar takes 40ms, so you'll see it and it'll feel a tiny bit sluggish.
But I can't have a 20ms wait on each widget resize, that would be
catastrophic to performance on windows with lots of widgets.
I tried hooking configure-event and size-allocate, but they were very
unreliable. So instead I ended up with a loop that waits up to a maximm
of 20ms that inspects the `widget->allocation.(width,height)` values
directly and waits for them to be what we asked for with
`set_size_request`.
There was some extreme ugliness in GTK with calling
`gtk_main_iteration_do` recursively (`hiro::Widget::setGeometry` is
called recursively), so I had to lock it to only happen on the top level
widgets (the child ones should get resized while waiting on the
top-level ones, so it should be fine in practice), and also only run it
on realized widgets.
Even still, I'm getting ~3 timeouts when opening the settings dialog in
higan, but no other windows. But, this is the best I can do for now.
And the reason for all of this pain? Yeah, updated the video code.
So the Emulator::Interface now has this:
struct VideoSize { uint width, height; }; //or requiem for a tuple
auto videoSize() -> VideoSize;
auto videoSize(uint width, uint height, bool arc) -> VideoSize;
The first function, for now, is just returning the literal surface size.
I may remove this ... one thing I want to allow for is cores that send
different texture sizes based on interlace/hires/overscan/etc settings.
The second function is more interesting. Instead of having the UI trying
to figure out sizing, I figure the emulation cores can do a better job
and we can customize it per-core now. So it gets the window's width and
height, and whether the user asked for aspect correction, and then
computes the best width/height ratio possible. For now they're all just
doing multiples of a 1x scale to the UI 2x,3x,4x modes.
We still need a third function, which will probably be what I repurpose
videoSize() for: to return the 'effective' size for pixel shaders, to
then feed into ruby, to then feed into quark, to then feed into our
shaders. Since shaders use normalized coordinates for pixel fetching,
this should work out just fine. The real texture size will be exposed to
quark shaders as well, of course.
Now for the main window ... it's just hard-coded to be 640x480, 960x720,
1280x960 for now. It works nicely for some cores on some modes, not so
much for others. Work in progress I guess.
I also took the opportunity to draw the about dialog box logo on the
main window. Got a bit fancy and used the old spherical gradient and
impose functionality of nall/image on it. Very minor highlight, nothing
garish. Just something nicer than a solid black window.
If you guys want to mess around with sizes, placements, and gradient
styles/colors/shapes ... feel free. If you come up with something nicer,
do share.
That's what led to all the GTK hell ... the logo wasn't drawing right as
you resized the window. But now it is, though I am not at all happy with
the hacking I had to do.
I also had to improve the video update code as a result of this:
- when you unload a game, it blacks out the screen
- if you are not quitting the emulator, it'll draw the logo; if
you are, it won't
- when you load a game, it black out the logo
These options prevent any unsightliness from resizing the viewport with
image data on it already
I need to redraw the logo when toggling fullscreen with no game loaded
as well for Windows, it seems.

(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.

declared]
- would be nice to remove the using lstring eventually ... but that'd
probably require 10,000 lines of changes >_>
- format -> string_format [no using here; format was too ambiguous]
- using integer = Integer<sizeof(int)*8>; and using natural =
Natural<sizeof(uint)*8>; declared
- for consistency with boolean. These three are meant for creating
zero-initialized values implicitly (various uses)
- R65816::io() -> idle() and SPC700::io() -> idle() [more clear; frees
up struct IO {} io; naming]
- SFC CPU, PPU, SMP use struct IO {} io; over struct (Status,Registers) {}
(status,registers); now
- still some CPU::Status status values ... they didn't really fit into
IO functionality ... will have to think about this more
- SFC CPU, PPU, SMP now use step() exclusively instead of addClocks()
calling into step()
- SFC CPU joypad1_bits, joypad2_bits were unused; killed them
- SFC PPU CGRAM moved into PPU::Screen; since nothing else uses it
- SFC PPU OAM moved into PPU::Object; since nothing else uses it
- the raw uint8[544] array is gone. OAM::read() constructs values from
the OAM::Object[512] table now
- this avoids having to determine how we want to sub-divide the two
OAM memory sections
- this also eliminates the OAM::synchronize() functionality
- probably more I'm forgetting
The FPS fluctuations are driving me insane. This WIP went from 128fps to
137fps. Settled on 133.5fps for the final build. But nothing I changed
should have affected performance at all. This level of fluctuation makes
it damn near impossible to know whether I'm speeding things up or slowing
things down with changes.
