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.

Changelog:
- reverted nall/inline-if.hpp usage for now, since the
nall/primitives.hpp math operators still cast to (u)int64_t
- improved nall/primitives.hpp more; integer8 x = -128; print(-x) will
now print 128 (unary operator+ and - cast to (u)int64_t)
- renamed processor/lr35902 to processor/sm83; after the Sharp SM83
CPU core [gekkio discovered the name]
- a few bugfixes to the TLCS900H CPU core
- completed the disassembler for the TLCS900H core
As a result of reverting most of the inline if stuff, I guess the
testing priority has been reduced. Which is probably a good thing,
considering I seem to have a smaller pool of testers these days.
Indeed, the TLCS900H core has ended up at 131KiB compared to the M68000
core at 128KiB. So it's now the largest CPU core in all of higan. It's
even more ridiculous because the M68000 core would ordinarily be quite a
bit smaller, had I not gone overboard with the extreme templating to
reduce instruction decoding overhead (you kind of have to do this for
RISC CPUs, and the inverted design of the TLCS900H kind of makes it
infeasible to do the same there.)
This CPU core is bound to have dozens of extremely difficult CPU bugs,
and there's no easy way for me to test them. I would greatly appreciate
any help in looking over the core for bugs. A fresh pair of eyes to spot
a mistake could save me up to several days of tedious debugging work.
The core still isn't ready to actually be tested: I have to hook up
cartridge loading, a memory bus, interrupts, timers, and the micro DMA
controller before it's likely that anything happens at all.
byuu says:
I've implemented a lot more TLCS900H instructions. There are currently
20 missing spots, all of which are unique instructions (well, MINC and
MDEC could be considered pairs of 3 each), from a map of 1024 slots.
After that, I have to write the disassembler. Then the memory bus. Then
I get to start the fun process of debugging this monstrosity.
Also new is nall/inline-if.hpp. Note that this file is technically a war
crime, so be careful when opening it. This replaces ternary() from the
previous WIP.
byuu says:
So this turned out to be a rather unproductive ten-hour rabbit hole, but
...
I reworked nall/primitives.hpp a lot. And because the changes are
massive, testing of this WIP for regressions is critically important. I
really can't stress that enough, we're almost certainly going to have
some hidden regressions here ...
We now have a nall/primitives/ subfolder that splits up the classes into
manageable components. The bit-field support is now shared between both
Natural and Integer. All of the assignment operator overloads are now
templated and take references instead of values. Things like the
GSU::Register class are non-copyable on account of the function<>
object inside of it, and previously only operator= would work with
classes like that.
The big change is nall/primitives/operators.hpp, which is a really
elaborate system to compute the minimum number of bits needed for any
operation, and to return a Natural<T> or Integer<T> when one or both of
the arguments are such a type.
Unfortunately, it doesn't really work yet ... Kirby's Dream Land 3
breaks if we include operators.hpp. Zelda 3 runs fine with this, but I
had to make a huge amount of core changes, including introducing a new
ternary(bool, lhs, rhs) function to nall/algorithm to get past
Natural<X> and Natural<Y> not being equivalent (is_integral types get a
special exemption to ternary ?: type equivalence, yet it's impossible to
simulate with our own classes, which is bullshit.) The horrifying part
is that ternary() will evaluate both lhs and rhs, unlike ?:
I converted some of the functions to test ? uint(x) : uint(y), and
others to ternary(test, x, y) ... I don't have a strong preference
either way yet.
But the part where things may have gotten broken is in the changes to
where ternary() was placed. Some cases like in the GBA PPU renderer, it
was rather unclear the order of evaluations, so I may have made a
mistake somewhere.
So again, please please test this if you can. Or even better, look over
the diff.
Longer-term, I'd really like the enable nall/primitives/operators.hpp,
but right now I'm not sure why Kirby's Dream Land 3 is breaking. Help
would be appreciated, but ... it's gonna be really complex and difficult
to debug, so I'm probably gonna be on my own here ... sigh.

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:
- 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
being cleared on track select
- nall: cryptography support added; will be used to sign future
databases (validation will always be optional)
- 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.

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:
Changelog:
- return open bus instead of mirroring addresses on the bus (fixes
Mario&Luigi, Minish Cap, etc) [Jonas Quinn]
- add boolean flag to load requests for slotted game carts (fixes slot
load prompts)
- rename BS-X Town cart from psram to ram
- icarus: add support for game database
Note: I didn't rename "bsx" to "mcc" in the database for icarus before
uploading that. But I just fixed it locally, so it'll be in the next
WIP. For now, make it create the manifest for you and then rename it
yourself. I did fix the PSRAM size to 256kbit.
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]
byuu says:
This updates higan to use the new Markup::Node changes. This is a really
big change, and one slight typo anywhere could break certain classes of
games from playing.
I don't have ananke hooked up again yet, so I don't have the ability to
test this much. If anyone with some v094 game folders wouldn't mind
testing, I'd help out a great deal.
I'm most concerned about testing one of each SNES special chip game.
Most notably, systems like the SA-1, HitachiDSP and NEC-DSP were using
the fancier lookups, eg node["rom[0]/name"], which I had to convert to
a rather ugly node["rom"].at(0)["name"], which I'm fairly confident
won't work. I'm going to blame that on the fumes from the shelves I just
stained >.> Might work with node.find("rom[0]/name")(0) though ...? But
so ugly ... ugh.
That aside, this WIP adds the accuracy-PPU inlining, so the accuracy
profile should run around 7.5% faster than before.
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.

Changelog:
- added Cocoa target: higan can now be compiled for OS X Lion
[Cydrak, byuu]
- SNES/accuracy profile hires color blending improvements - fixes
Marvelous text [AWJ]
- fixed a slight bug in SNES/SA-1 VBR support caused by a typo
- added support for multi-pass shaders that can load external textures
(requires OpenGL 3.2+)
- added game library path (used by ananke->Import Game) to
Settings->Advanced
- system profiles, shaders and cheats database can be stored in "all
users" shared folders now (eg /usr/share on Linux)
- all configuration files are in BML format now, instead of XML (much
easier to read and edit this way)
- main window supports drag-and-drop of game folders (but not game files
/ ZIP archives)
- audio buffer clears when entering a modal loop on Windows (prevents
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.
