The latest WIP renames icarus/database and icarus/firmware to
icarus/Database and icarus/Firmware (in title case).
Also, somewhere along the line we stopped building icarus for higan/Linux,
which seems an oversight.

This synchronizes bsnes/higan with many recent internal nall changes.
This will be the last WIP until I am situated in Japan. Apologies for the
bugfixes that didn't get applied yet, I ran out of time.
byuu says:
Changelog:
- sfc: completed BS Memory Cassette emulation (sans bugs, of course --
testing appreciated)
- bsnes: don't strip - on MSU1 track names in game ROM mode
[hex_usr]
I'm going with "metadata.bml" for the flash metadata filename for the
time being, but I'll say that it's subject to change. I'll have to make
a new extension for it to be supported with bsnes.
byuu says:
Changelog:
- gb/mbc7: rewrote the 93LCx6 EEPROM emulation
- sfc/slot/bsmemory: rewrote the flash emulation for Satellaview
cartridges
As of this release, flash-based BS Memory cartridges will be writable.
So without the bsnes patch to disable write limits, some games will lock
out after a few plays.
byuu says:
Changelog:
- sfc/cx4: added missing instructions [info from Overload]
- sfc/cx4: added instruction cache emulation [info from ikari]
- sfc/sa1: don't let CPU access SA1-only I/O registers, and vice versa
- sfc/sa1: fixed IRQs that were broken from the recent WIP
- sfc/sa1: significantly improved bus conflict emulation
- all tests match hardware now, other than HDMA ROM↔ROM, which
is 0.5 - 0.8% too fast
- sfc/cpu: fixed a bug with DMA→CPU alignment timing
- sfc/cpu: removed the DMA pipe; performs writes on the same cycles as
reads [info from nocash]
- sfc/memory: fix a crashing bug due to not clearing Memory size field
[hex_usr]
- bsnes/gb: use .rtc for real-time clock file extensions on the Game
Boy [hex_usr]
- ruby/cgl: compilation fix [Sintendo]
Now let's see if I can accept being off by ~0.65% on one of twelve SA1
timing tests for the time being and prioritize much more important
things or not.
byuu says:
This release adds ikari's Cx4 notes to bsnes. It fixes the MMX2 intro's
boss fight sequence to be frame perfect to real hardware. It's also very
slightly faster than before.
I've also added an option to toggle the CPU↔coprocessor cycle
synchronization to the emulation settings panel, so you don't have to
recompile to get the more accurate SA1 timings. I'm most likely going to
default this to disabled in bsnes, and *maybe* enabled in higan out of
the box.
StaticRAM (wasn't used) and MappedRAM are gone from the Super Famicom
core. Instead, there's now ReadableMemory, WritableMemory, and
ProtectedMemory (WritableMemory with a toggle for write protection.)
Cartridge::loadMap now takes a template Memory object, which bypasses an
extra virtual function call on memory accesses, but it doesn't really
impact speed much. Whatever.
byuu says:
I added (imperfect) memory conflict timing to the SA1.
Before:
- WRAM↔↔ROM ran 7% too fast
- ROM↔↔ROM ran 100% too fast
- WRAM↔↔IRAM ran 7% too fast
- ROM↔↔IRAM ran 7% too fast
- IRAM↔↔IRAM ran 287% too fast
- BWRAM↔↔BWRAM ran 100% too fast
- HDMA ROM↔↔ROM ran 15% too fast
- HDMA WRAM↔↔ROM ran 15% too fast
- DMA ROM↔↔ROM ran 100% too fast
After:
- ROM↔↔ROM runs 14% too fast
- HDMA WRAM↔↔ROM runs 7% too fast
- DMA ROM↔↔ROM runs 4% too fast
If you enable this with the fast PPU + DSP, your framerate in SA1 games
will drop by 51%. And even if you disable it, you'll still lose 9% speed
in SA1 games, and 2% speed in non-SA1 games, because of changes needed
to make this support possible.
By default, I'm leaving this off. Compile with `-DACCURATE_SA1` (or
uncomment the line in sfc/sfc.hpp) if you want to try it out.
This'll almost certainly cause some SA1 regressions, so I guess we'll
tackle those as they arise.
byuu says:
Changelog:
- fixed bug in Emulator::Game::Memory::operator bool()

- 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
- icarus: Game Boy, Super Famicom, Mega Drive cores output internal
header game titles to heuristics manifests
- higan, icarus, hiro/gtk: improve viewport geometry configuration;

- 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.
Previously the Makefile, when run on Windows, expected the uname command to report either "MINGW" or "windows32". This was unfortunate because the uname included in Git for Windows reports "MSYS".
With this change, the Makefile will work properly with any uname, whether it comes from MinGW, GnuWin32 or Git for Windows.
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:
This release fixes the XAudio 2.1 and WASAPI drivers on Windows, and
extends XAudio to support device selection (eg headphones, speakers,
monitor, etc.) It also adds DRC to XAudio, however it's not currently
working.
The code is courtesy of Talarubi, I just botched it somewhere upon
porting it to the newer version of ruby.
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.
The WonderSwan Color came out in 2000 and the GBA in 2001, so technically
they're not "video-game consoles of the 1980s and 1990s". Since there's no
elegant way to talk about the 2000-2009 timespan, let's just not mention
dates at all.
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.
byuu says:
These WIPs-within-WIPs are getting more and more broken ... this isn't
going the way I wanted.
But ... this time around, I've revamped the entire ruby API again, to
solve a bunch of tough problems that have always made using ruby really
clunky.
But there are *so many* ruby drivers that it's going to take a long
time to work through them all. This WIP is only going to run bsnes, and
only on FreeBSD, and only with some drivers.
hiro's Application::initialize() now calls hiro::initialize(), which you
define inside of your hiro apps. This lets you call
Application::setName(...) before anything else in hiro runs. This is
essential on Xorg to set program icons, for instance.
With the ruby rewrite and the change to hiro, I can get away from the
need to make everything in bsnes/higan pointers to objects, and can now
just declare them as regular objects.

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.
