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.

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.

Changelog:
- ruby: ported all remaining drivers to new API¹
- ruby/wasapi: fix for dropping one sample per period [SuperMikeMan]
- gb: emulated most of the TAMA RTC; but RTC state is still volatile²
¹: the new ports are:
- audio/{directsound, alsa, pulseaudio, pulseaudiosimple, ao}
- input/{udev, quartz, carbon}
It's pretty much guaranteed many of them will have compilation errors.
Please paste the error logs and I'll try to fix them up. It may take a
WIP or two to get there.
It's also possible things broke from the updates. If so, I could use
help comparing the old file to the new file, looking for mistakes, since
I can't test on these platforms apart from audio/directsound.
Please report working drivers in this list, so we can mark them off the
list. I'll need both macOS and Linux testers.
audio/directsound.cpp:112:
if(DirectSoundCreate(0, &_interface, 0) != DS_OK) return terminate(), false;
²: once I get this working, I'll add load/save support for the RTC
values. For now, the RTC data will be lost when you close the emulator.
Right now, you can set the date/time in real-time mode, and when you
start the game, the time will be correct, and the time will tick
forward. Note that it runs off emulated time instead of actual real
time, so if you fast-forward to 300%, one minute will be 20 seconds.
The really big limitation right now is that when you exit the game, and
restart it, and resume a new game, the hour spot gets corrupted, and
this seems to instantly kill your pet. Fun. This is crazy because the
commands the game sends to the TAMA interface are identical between
starting a new game and getting in-game versus loading a game.
It's likely going to require disassembling the game's code and seeing
what in the hell it's doing, but I am extremely bad at LR35092 assembly.
Hopefully endrift can help here :|

Changelog:
- ruby: rewrote the API interfaces for Video, Audio, Input
- ruby/audio: can now select the number of output channels (not useful
to higan, sorry)
- ruby/asio: various improvements
- tomoko: audio settings panel can now select separate audio devices
(for ASIO, OSS so far)
- tomoko: audio settings panel frequency and latency lists are
dynamically populated now
Note: due to the ruby API rewrite, most drivers will not compile. Right
now, the following work:
- video: Direct3D, XShm
- audio: ASIO, OSS
- input: Windows, SDL, Xlib
It takes a really long time to rewrite these (six hours to do the
above), so it's going to be a while before we're back at 100%
functionality again.
Errata:
- ASIO needs device(), setDevice()
- need to call setDevice() at program startup to populate
frequency/latency settings properly
- changing the device and/or frequency needs to update the emulator
resampler rates
The really hard part is going to be the last one: the only way to change
the emulator frequency is to flush all the audio streams and then
recompute all the coefficients for the resamplers. If this is called
during emulation, all audio streams will be erased and thus no sound
will be output. I'll most likely be forced to simply ignore
device/frequency changes until the user loads another game. It is at
least possible to toggle the latency dynamically.
byuu says:
This WIP substantially restructures the ruby API for the first time
since that project started.
It is my hope that with this restructuring, destruction of the ruby
objects should now be deterministic, which should fix the crashing on
closing the emulator on Linux. We'll see I guess ... either way, it
removed two layers of wrappers from ruby, so it's a pretty nice code
cleanup.
It won't compile on Windows due to a few issues I didn't see until
uploading the WIP, too lazy to upload another. But I fixed all the
compilation issues locally, so it'll work on Windows again with the next
WIP (unless I break something else.)
(Kind of annoying that Linux defines glActiveTexture but Windows
doesn't.)
byuu says:
The library window is gone, and replaced with
hiro::BrowserWindow::openFolder(). This gives navigation capabilities to
game loading, and it also completes our slotted cart selection code. As
an added bonus, it's less code this way, too.
I also set the window size to consistent sizes between all emulated
systems, so that switching between SFC and GB don't cause the window
size to keep changing, and so that the scaling size is consistent (eg at
normal scale, GB @ 3x is closer to SNES @ 2x.) This means black borders
in GB/GBA mode, but it doesn't look that bad, and it's not like many
people ever use these modes anyway.
Finally, added the placeholder tabs for video, audio and timing. I don't
intend to add the timing calculator code to v095 (it might be better as
a separate tool), but I'll add the ability to set video/audio rates, at
least.
Glitch 1: despite selecting the first item in the BrowserDialog list, if
you press enter when the window appears, it doesn't activate the item
until you press an arrow key first.
Glitch 2: in Game Boy mode, if you set the 4x window size, it's not
honoring the full requested height because the viewport is smaller than
the window. 8+ years of trying to get GTK+ and Qt to simply set the god
damned window size I ask for, and I still can't get them to do it
reliably.
Remaining issues:
- finish configuration panels (video, audio, timing)
- fix ruby driver compilation on Windows
- add DIP switch selection window (NSS) [I may end up punting this one
to v096]

This updates ruby to return shared_pointer<HID::Device> objects instead
of HID::Device* objects. It also fixes an ID bug where joypads were
starting at ID# 2+, but mice were also set to ID# 2. I also revised
nall/hid a lot, with getters and setters instead of stabbing at internal
state. I didn't yet patch nall::string to safely consume nullptr const
char* values, though.

Not an official WIP (a WIP WIP? A meta-WIP?), just throwing in the new
fullscreen code, and I noticed that OpenGL colors in 30-bit mode are all
fucked up now for some strange reason. So I'm just using this snapshot
to debug the issue.
byuu says:
I've completely redone the ethos InputManager and ruby to work on
HID::Device objects instead of one giant scancode pool.
Currently only the udev driver supports the changes to ruby, so only
Linux users will be able to compile and run this WIP build.
The nice thing about the new system is that it's now possible to
uniquely identify controllers, so if you swap out gamepads, you won't
end up with it working but with all the mappings all screwed up. Since
higan lets you map multiple physical inputs to one emulated input, you
can now configure your keyboard and multiple gamepads to the same
emulated input, and then just use whatever controller you want.
Because USB gamepad makers failed to provide unique serial#s with each
controller, we have to limit the mapping to specific USB ports.
Otherwise, we couldn't distinguish two otherwise identical gamepads. So
basically your computer USB ports act like real game console input port
numbers. Which is kind of neat, I guess.
And the really nice thing about the new system is that we now have the
capability to support hotplugging input devices. I haven't yet added
this to any drivers, but I'm definitely going to add it to udev for v094
official.
Finally, with the device ID (vendor ID + product ID) exposed, we gain
one last really cool feature that we may be able to develop more in the
future. Say we created a joypad.bml file to include with higan. In it,
we'd store the Xbox 360 controller, and pre-defined button mappings for
each emulated system. So if higan detects you have an Xbox 360
controller, you can just plug it in and use it. Even better, we can
clearly specify the difference between triggers and analog axes, and
name each individual input. So you'd see "Xbox 360 Gamepad #1: Left
Trigger" instead of higan v093's "JP0::Axis2.Hi"
Note: for right now, ethos' input manager isn't filtering the device IDs
to look pretty. So you're going to see a 64-bit hex value for a device
ID right now instead of something like Joypad#N for now.

audio repetition with DirectSound driver)
- a substantial amount of code clean-up (probably the biggest
refactoring to date)
One highly desired target for this release was to default to the optimal
drivers instead of the safest drivers, but because AMD drivers don't
seem to like my OpenGL 3.2 driver, I've decided to postpone that. AMD
has too big a market share. Hopefully with v093 officially released, we
can get some public input on what AMD doesn't like.
byuu describes the changes since v067:
This release officially introduces the accuracy and performance cores,
alongside the previously-existing compatibility core. The accuracy core
allows the most accurate SNES emulation ever seen, with every last
processor running at the lowest possible clock synchronization level.
The performance core allows slower computers the chance to finally use
bsnes. It is capable of attaining 60fps in standard games even on an
entry-level Intel Atom processor, commonly found in netbooks.
The accuracy core is absolutely not meant for casual gaming at all. It
is meant solely for getting as close to 100% perfection as possible, no
matter the cost to speed. It should only be used for testing,
development or debugging.
The compatibility core is identical to bsnes v067 and earlier, but is
now roughly 10% faster. This is the default and recommended core for
casual gaming.
The performance core contains an entirely new S-CPU core, with
range-tested IRQs; and uses blargg's heavily-optimized S-DSP core
directly. Although there are very minor accuracy tradeoffs to increase
speed, I am confident that the performance core is still more accurate
and compatible than any other SNES emulator. The S-CPU, S-SMP, S-DSP,
SuperFX and SA-1 processors are all clock-based, just as in the accuracy
and compatibility cores; and as always, there are zero game-specific
hacks. Its compatibility is still well above 99%, running even the most
challenging games flawlessly.
If you have held off from using bsnes in the past due to its system
requirements, please give the performance core a try. I think you will
be impressed. I'm also not finished: I believe performance can be
increased even further.
I would also strongly suggest Windows Vista and Windows 7 users to take
advantage of the new XAudio2 driver by OV2. Not only does it give you
a performance boost, it also lowers latency and provides better sound by
way of skipping an API emulation layer.
Changelog:
- Split core into three profiles: accuracy, compatibility and
performance
- Accuracy core now takes advantage of variable-bitlength integers (eg
uint24_t)
- Performance core uses a new S-CPU core, written from scratch for speed
- Performance core uses blargg's snes_dsp library for S-DSP emulation
- Binaries are now compiled using GCC 4.5
- Added a workaround in the SA-1 core for a bug in GCC 4.5+

Quinn]; fixing Mega Man X2 "gained weapon" star background effect
- Updated video renderer to properly handle mixed-resolution screens
with interlace enabled; fixing Air Strike Patrol level briefing screen
- Added mightymo's 2010-08-19 cheat code pack
- Windows port: added XAudio2 output support [OV2]
- Source: major code restructuring; virtual base classes for processor
- cores removed, build system heavily modified, etc.
