From the MSVC docs: "You can use the /permissive- compiler option to
specify standards-conforming compiler behavior. This option disables
permissive behaviors, and sets the /Zc compiler options for strict
conformance."
While generally a positive thing, this does make MSVC stricter than
GCC/Clang in some cases. A couple of things popped out:
- nall::multiFactorImage had a busted constructor. I fixed this and did
some other cleanup while I was at it.
- nall::string has an implicit conversion operator to const char*. This
is honestly really ugly and creates ambiguity and allows for all kinds
of surprising silent conversions. Unfortunately, fixing that (by making
it explicit) will require touching hundreds of lines of code so I opted
not to deal with it now. Instead I fixed the much smaller number of
ambigous cases relating to string literals.
- ruby: removed Input::onHotplug(); luna and lucia handle hot-plugging
automatically
- Famicom: refactored SxROM and MMC1 into a single class
- Famicom: converted generic class variable types (bool, uint) to
uint# types
- Game Boy Advance: fixed a bug with keypad interrupt handling (keypad
array was erroneously marked static)
- all: moved inline designators from function designators to function
declarations
Initial release; fork of **higan** v110.
- the project and core library is now called **ares**
- the simplified user interface is now called **lucia**
- the advanced user interface is now called **luna**
- the game analyzer is now called **mia**
- removed the database editor **genius** from the project
- PC Engine: adjusted rendering viewport for the scanline renderer
from Y=18 to Y=21

I've added a waveOut audio driver for Windows (no DRC), and hooked up a lot more
neo geo pocket stuff (gamepad polling, APU/Z80 enable/disable, APU->CPU IRQs,
VPU I/O registers, etc.) still not enough to get any further than we already
were, sigh.

Another thirteen hours ... Concerta is a hell of a drug.
Okay, so this is a partial merging of Screwtape and bun's suggestions
for a multi-pane layout.
The configuration manager shows the list of systems on the left, and you
can choose to create a new system in the right pane, or to see
(read-only) the current connections of a given system entry. For right
now, there's just a simple logo display on the right when no systems are
selected and you're not in create mode. I imagine it will make more
sense to list the systems on the right when not showing a specific
system connections list, but ... I wanted to put the icon there for now.
To do that, I wrote a new nall::image function, shrink(), which detects
all entirely blank/transparent rows/columns on all four sides of an
image, and then crops them out. I could have just used Imagemagick on
the icon.png file, but ... overkill is more fun.
My thoughts were, maybe in the future, we can populate it as a kind of
"home" screen with some more things. Have to think about it.
The system manager window shows the connections on the left, and you can
edit either port↔peripheral connections or input mappings on the
right. And in the future, settings and other such things as well. The
system manager also has a "blank" panel, but this time it's just a
disabled, empty TreeView (so that the frame matches the other panels.)
We could put anything here as well in the future ...
There's new hiro classes, HorizontalResizeGrip and VerticalResizeGrip.
The former is used to let you resize the two panels.
I burned a lot of time reimplementing the horizontal scroll bar display
in GtkTreeView, because GTK's implementation was busted, ignored icon
indentations, and showed the scrollbar way too early.
The tree views now render little L bracket things to help show
indentation a bit better. Unfortunately my GTK themes can't do this even
with the extenders visible, so this is the best I can do in a
cross-platform manner for now ...
If we decide to give up on tree views ... we will have to lose the icons
(and the chance of any nicer node-specific icons in the future), because
the TableViewItem icons always appear at the far left. I might consider
it anyway because I really don't want to port TreeView to Windows, Qt,
and MacOS.
I turned back on the GTK alternating row colors for a bit, to make the
input mapping panel a bit easier to read.
I cleaned up a lot of the SNES core code as well. The Super Multitap is
back, and functions like a real Super Multitap for the first time ever.
There is the possibility of a controller that passes through the iobit
lines to PIO d6/d7, but for now, the only controller we emulate with
extra ports (save for maybe the dual Justifier) is the Multitap, and it
doesn't pass through the iobits to its connected children, so for now
I'm just having anything other than controller ports 1&2 return 0 from
iobit reads, and ignore iobit writes. The ControllerPorts implement
wrappers for the Controller functions (iobit, data, latch) so that the
Controller* device object can be a nullptr.
Expansions are connectable again. There's a new Thread::destroy() to
both release a cothread_t and remove it from the scheduler threads
list. I still regrettably have to also remove the threads from the
cpu.coprocessors/cpu.peripherals vectors (speaking of, I should
double-check that the peripherals do this right.) All of the
coprocessors have been updated to properly do all of this, and handle
thread attach/detach inside their own unload/power functions, instead of
in System/Cartridge::power,unload.
The Satellaview maps data onto and off the SNES bus, but ultimately this
should be okay because the expansion port isn't hot-swappable. If you
forcefully do it anyway, it should still work since nothing else maps to
those ranges except for the 21fx.
I updated hiro's setAlignment functions to replace the newer
setPlacement with something even more flexible. Love it or hate it,
higan now places the system manager window in the center of the screen,
and when you power on a system, it centers the video, and then moves the
system manager to the left of the video output. When you close the video
output, it acts like an unload event and moves the system manager back.
If the system manager is either minimized or maximized, it won't move it
on power on (though currently you can't power the system on with the
system manager minimized, but maybe later with a hotkey ...) When you
close the video window, it'll unminimize the system manager if you did
that, and then center it ... unless it was maximized.
Unserializing node.bml tables got a lot more strict. Now only Setting
values and Property values can be unserialized into the root tree, and
only when both the type (identity) and name of the node matches up. This
should hopefully help to prevent incompatibilities as the node.bml
structure changes.
If you right-click on a port, you can change the path it looks for
things in. This is a bit hidden, and the port connection panel should
really tell you where it's looking as well. We'll get there.
I'm sure there's a lot more, but that's all I can remember right now.

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.

et al⁴
¹: because there's no concept of a controller for cartridge inputs,
I'm attaching to the base platform for now. An idea I had was to make
separate ports for each cartridge type ... but this would duplicate the
rumble input between MBC5 and MBC7. And would also be less discoverable.
But it would be more clean in that users wouldn't think the Game Boy
hardware had this functionality. I'll think about it.
²: it probably won't work yet. Rumble isn't documented anywhere, but
I dug through an emulator named GEST and discovered that it seems to use
bit 3 of the RAM bank select to be rumble. I don't know if it sets the
bit for rumbling, then clears when finished, or if it sets it and then
after a few milliseconds it stops rumbling. I couldn't test on my
FreeBSD box because SDL 1.2 doesn't support rumble, udev doesn't exist
on FreeBSD, and nobody has ever posted any working code for how to use
evdev (or whatever it's called) on FreeBSD.
³: I'm still thinking about specifying the MBC7 RAM as EEPROM, since
it's not really static RAM.
⁴: if possible, please test all drivers if you can. I want to ensure
they're all working. Especially let me know if the following work:
macOS: input.carbon Linux: audio.pulseaudiosimple, audio.ao (libao)
If I can confirm these are working, I'm going to then remove them from
being included with stock higan builds.
I'm also considering dropping SDL video on Linux/BSD. XShm is much
faster and supports blurring. I may also drop SDL input on Linux, since
udev works better. That will free a dependency on SDL 1.2 for building
higan. FreeBSD is still going to need it for joypad support, however.

New update. Most of the work today went into eliminating hiro::Image
from all objects in all ports, replacing with nall::image. That took an
eternity.
Changelog:
- fixed crashing bug when loading games [thanks endrift!!]
- toggling "show status bar" option adjusts window geometry (not
supposed to recenter the window, though)
- button sizes improved; icon-only button icons no longer being cut off
byuu says:
Updated to compile with all of the new hiro changes. My next step is to
write up hiro API documentation, and move the API from alpha (constantly
changing) to beta (rarely changing), in preparation for the first stable
release (backward-compatible changes only.)
Added "--fullscreen" command-line option. I like this over
a configuration file option. Lets you use the emulator in both modes
without having to modify the config file each time.
Also enhanced the command-line game loading. You can now use any of
these methods:
higan /path/to/game-folder.sfc
higan /path/to/game-folder.sfc/
higan /path/to/game-folder.sfc/program.rom
The idea is to support launchers that insist on loading files only.
Technically, the file can be any name (manifest.bml also works); the
only criteria is that the file actually exists and is a file, and not
a directory. This is a requirement to support the first version (a
directory lacking the trailing / identifier), because I don't want my
nall::string class to query the file system to determine if the string
is an actual existing file or directory for its pathname() / dirname()
functions.
Anyway, every game folder I've made so far has program.rom, and that's
very unlikely to change, so this should be fine.
Now, of course, if you drop a regular "game.sfc" file on the emulator,
it won't even try to load it, unless it's in a folder that ends in .fc,
.sfc, etc. In which case, it'll bail out immediately by being unable to
produce a manifest for what is obviously not really a game folder.

Changelog (since the last open beta):
- icarus is now included. icarus is used to import game files/archives
into game paks (folders)
- SNES: mid-scanline BGMODE changes now emulated correctly (used only by
atx2.smc Anthrox Demo)
- GBA: fixed a CPU bug that was causing dozens of games to have
distorted audio
- GBA: fixed default FlashROM ID; should allow much higher compatibility
- GBA: now using Cydrak's new, much improved, GBA color emulation filter
(still a work-in-progress)
- re-added command-line loading support for game paks (not for game
files/archives, sorry!)
- Qt port now compiles and runs again (may be a little buggy;
Windows/GTK+ ports preferred)
- SNES performance profile now compiles and runs again
- much more

- fixed Baldur's Gate bug
- guess if no flash ROM ID present (fixes Magical Vacation, many many
others)
- nall cleanups
- sfc/cartridge major cleanups
- bsxcartridge/"bsx" renamed to mcc/"mcc" after the logic chip it uses
(consistency with SGB/ICD2)
- ... and more!
byuu says:
Added AWJ's fixes for alt/cpu (Tetris Attack framelines issue) and
alt/dsp (Thread::clock reset)
Added fix so that the taskbar entry appears when the application first
starts on Windows.
Fixed checkbox toggling inside of list views on Windows.
Updated nall/image to properly protect variables that should not be
written externally.
New Object syntax for hiro is in.
Fixed the backwards-typing on Windows with the state manager.
NOTE: the list view isn't redrawing when you change the description
text. It does so on the cheat editor because of the resizeColumns call;
but that shouldn't be necessary. I'll try and fix this for the next WIP.
byuu says:
Finally!! Compilation works once again on Windows.
However, it's pretty buggy. Modality isn't really working right, you can
still poke at other windows, but when you select ListView items, they
redraw as empty boxes (need to process WM_DRAWITEM before checking
modality.)
The program crashes when you close it (probably a ruby driver's term()
function, that's what it usually is.)
The Layout::setEnabled(false) call isn't working right, so you get that
annoying chiming sound and cursor movement when mapping keyboard keys to
game inputs.
The column sizing seems off a bit on first display for the Hotkeys tab.
And probably lots more.
byuu says:
This will easily be the biggest diff in the history of higan. And not in
a good way.
* target-higan and target-loki have been blown away completely
* nall and ruby massively updated
* phoenix replaced with hiro (pretty near a total rewrite)
* target-higan restarted using hiro (just a window for now)
* all emulation cores updated to compile again
* installation changed to not require root privileges (installs locally)
For the foreseeable future (maybe even permanently?), the new higan UI
will only build under Linux/BSD with GTK+ 2.20+. Probably the most
likely route for Windows/OS X will be to try and figure out how to build
hiro/GTK on those platforms, as awful as that would be. The other
alternative would be to produce new UIs for those platforms ... which
would actually be a good opportunity to make something much more user
friendly.
Being that I just started on this a few hours ago, that means that for
at least a few weeks, don't expect to be able to actually play any
games. Right now, you can pretty much just compile the binary and that's
it. It's quite possible that some nall changes didn't produce
compilation errors, but will produce runtime errors. So until the UI can
actually load games, we won't know if anything is broken. But we should
mostly be okay. It was mostly just trim<1> -> trim changes, moving to
Hash::SHA256 (much cleaner), and patching some reckless memory copy
functions enough to compile.
Progress isn't going to be like it was before: I'm now dividing my time
much thinner between studying and other hobbies.
My aim this time is not to produce a binary for everyone to play games
on. Rather, it's to keep the emulator alive. I want to be able to apply
critical patches again. And I would also like the base of the emulator
to live on, for use in other emulator frontends that utilize higan.
byuu says:
This release adds support for game libraries, and substantially improves
Game Boy and Game Boy Color emulation with cycle-based renderers. Many
other changes are also present.
It's very important to note that this release now defaults to optimal
drivers rather than safe drivers. This is particularly important if you
do not have strong OpenGL 3.2 drivers. If performance is bad, go to
Settings -> Configuration -> Advanced, change the video driver, and
restart higan. In the rare case that you have trouble opening higan, you
can edit settings.bml directly and change the setting there. The Windows
safe driver is Direct3D, and the Linux safe driver is XShm.
Also note that although display emulation shaders are now supported,
they have not been included in this release as they are not ready yet.
The support has been built-in anyway, so that they can be tested by
everyone. Once refined, future releases of higan will come with built-in
shaders for each emulated system that simulates the unique display
characteristics of each.

byuu says:
This WIP removes nall/input.hpp entirely, and implements the new
universal cheat format for FC/SFC/GB/GBC/SGB.
GBA is going to be tricky since there's some consternation around
byte/word/dword overrides.
It's also not immediately obvious to me how to implement the code search
in logarithmic time, due to the optional compare value.
Lastly, the cheat values inside cheats.bml seem to be broken for the
SFC. Likely there's a bug somewhere in the conversion process. Obviously
I'll have to fix that before v094.
I received no feedback on the universal cheat format. If nobody adds
anything before v094, then I don't want to hear any complaining about
the formatting :P
