Update to v085r08 release.
byuu says:
Changelog:
- follow the Laevateinn topic to get most of it
- also added NMI, IRQ step buttons to CPU debugger
- also added trace masking + trace mask reset
- also added memory export
- cartridge loading is entirely folder-based now
FitzRoy, I'll go ahead and make a second compromise with you for v086:
I'll match the following:
/path/to/SNES.sfc/*.sfc
/path/to/NES.fc/*.prg, *.chr (split format)
/path/to/NES.fc/*.fc (merged format)
/path/to/GB.gb/*.gb
/path/to/GBC.gbc/*.gbc
Condition will be that there can only be one of each file. If there's
more than one, it'll abort. That lets me name my ROMs as
"Game.fc/Game.fc", and you can name yours as "Game.fc/cartridge.prg,
cartridge.chr". Or whatever you want.
We'll just go with that, see what fares out as the most popular, and
then restrict it back to that method.
The folder must have the .fc, etc extension though. That will be how we
avoid false-positive folder matches.
[Editor's note - the Laevateinn topic mentions these changes for
v085r08:
Added SMP/PPU breakpoints, SMP debugger, SMP stepping / tracing,
memory editing on APU-bus / VRAM / OAM / CGRAM, save state menu,
WRAM mirroring on breakpoints, protected MMIO memory regions
(otherwise, viewing $002100 could crash your game.)
Major missing components:
- trace mask
- trace mask clear / usage map clear
- window geometry caching / sizing improvements
- VRAM viewer
- properties viewer
- working memory export button
The rest will most likely appear after v086 is released.

Update to v102r02 release.
byuu says:
Changelog:
- I caved on the `samples[] = {0.0}` thing, but I'm very unhappy about it
- if it's really invalid C++, then GCC needs to stop accepting it
in strict `-std=c++14` mode
- Emulator::Interface::Information::resettable is gone
- Emulator::Interface::reset() is gone
- FC, SFC, MD cores updated to remove soft reset behavior
- split GameBoy::Interface into GameBoyInterface,
GameBoyColorInterface
- split WonderSwan::Interface into WonderSwanInterface,
WonderSwanColorInterface
- PCE: fixed off-by-one scanline error [hex_usr]
- PCE: temporary hack to prevent crashing when VDS is set to < 2
- hiro: Cocoa: removed (u)int(#) constants; converted (u)int(#)
types to (u)int_(#)t types
- icarus: replaced usage of unique with strip instead (so we don't
mess up frameworks on macOS)
- libco: added macOS-specific section marker [Ryphecha]
So ... the major news this time is the removal of the soft reset
behavior. This is a major!! change that results in a 100KiB diff file,
and it's very prone to accidental mistakes!! If anyone is up for
testing, or even better -- looking over the code changes between v102r01
and v102r02 and looking for any issues, please do so. Ideally we'll want
to test every NES mapper type and every SNES coprocessor type by loading
said games and power cycling to make sure the games are all cleanly
resetting. It's too big of a change for me to cover there not being any
issues on my own, but this is truly critical code, so yeah ... please
help if you can.
We technically lose a bit of hardware documentation here. The soft reset
events do all kinds of interesting things in all kinds of different
chips -- or at least they do on the SNES. This is obviously not ideal.
But in the process of removing these portions of code, I found a few
mistakes I had made previously. It simplifies resetting the system state
a lot when not trying to have all the power() functions call the reset()
functions to share partial functionality.
In the future, the goal will be to come up with a way to add back in the
soft reset behavior via keyboard binding as with the Master System core.
What's going to have to happen is that the key binding will have to send
a "reset pulse" to every emulated chip, and those chips are going to
have to act independently to power() instead of reusing functionality.
We'll get there eventually, but there's many things of vastly greater
importance to work on right now, so it'll be a while. The information
isn't lost ... we'll just have to pull it out of v102 when we are ready.
Note that I left the SNES reset vector simulation code in, even though
it's not possible to trigger, for the time being.
Also ... the Super Game Boy core is still disconnected. To be honest, it
totally slipped my mind when I released v102 that it wasn't connected
again yet. This one's going to be pretty tricky to be honest. I'm
thinking about making a third GameBoy::Interface class just for SGB, and
coming up with some way of bypassing platform-> calls when in this
mode.

Update to v098r12 release.
byuu says:
Changelog:
- higan/video: added support for Emulator::Sprite
- higan/resource: a new system for accessing embedded binary files
inside the emulation cores; holds the sprites
- higan/sfc/superscope,justifier: re-enabled display of crosshairs
- higan/sfc/superscope: fixed turbo toggle (also shows different
crosshair color when in turbo mode)
- higan/sfc/ppu: always outputs at 512x480 resolution now
- causes a slight speed-hit from ~127fps to ~125fps;
- but allows high-resolution 32x32 cursors that look way better;
- also avoids the need to implement sprite scaling logic
Right now, the PPU code to always output at 480-height is a really gross
hack. Don't worry, I'll make that nicer before release.
Also, superscope.cpp and justifier.cpp are built around a 256x240
screen. But since we now have 512x480, we can make the cursor's movement
much smoother by doubling the resolution on both axes. The actual games
won't see any accuracy improvements when firing the light guns, but the
cursors will animate nicer so I think it's still worth it. I'll work on
that before the next release as well.
The current 32x32 cursors are nicer, but we can do better now with full
24-bit color. So feel free to submit alternatives. I'll probably reject
them, but you can always try :D
The sprites don't support alpha blending, just color keying (0x00000000
= transparent; anything else is 0xff......). We can revisit that later
if necessary.
The way I have it designed, the only files that do anything with
Emulator::Sprite at all are the superscope and justifier folders.
I didn't have to add any hooks anywhere else. Rendering the sprite is
a lot cleaner than the old code, too.

Update to v099r14 release.
byuu says:
Changelog:
- (u)int(max,ptr) abbreviations removed; use _t suffix now [didn't feel
like they were contributing enough to be worth it]
- cleaned up nall::integer,natural,real functionality
- toInteger, toNatural, toReal for parsing strings to numbers
- fromInteger, fromNatural, fromReal for creating strings from numbers
- (string,Markup::Node,SQL-based-classes)::(integer,natural,real)
left unchanged
- template<typename T> numeral(T value, long padding, char padchar)
-> string for print() formatting
- deduces integer,natural,real based on T ... cast the value if you
want to override
- there still exists binary,octal,hex,pointer for explicit print()
formatting
- lstring -> string_vector [but using lstring = string_vector; is
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.

Update to v068r12 release.
(there was no r11 release posted to the WIP thread)
byuu says:
This took ten hours of mind boggling insanity to pull off.
It upgrades the S-PPU dot-based renderer to fetch one tile, and then
output all of its pixels before fetching again. It sounds easy enough,
but it's insanely difficult. I ended up taking one small shortcut, in
that rather than fetch at -7, I fetch at the first instance where a tile
is needed to plot to x=0. So if you have {-3 to +4 } as a tile, it
fetches at -3. That won't work so well on hardware, if two BGs fetch at
the same X offset, they won't have time.
I have had no luck staggering the reads at BG1=-7, BG3=-5, etc. While
I can shift and fetch just fine, what happens is that when a new tile is
fetched in, that gives a new palette, priority, etc; and this ends up
happening between two tiles which results in the right-most edges of the
screen ending up with the wrong colors and such.
Offset-per-tile is cheap as always. Although looking at it, I'm not sure
how BG3 could pre-fetch, especially with the way one or two OPT modes
can fetch two tiles.
There's no magic in Hoffset caching yet, so the SMW1 pixel issue is
still there.
Mode 7 got a bugfix, it was off-by-one horizontally from the mosaic
code. After re-designing the BG mosaic, I ended up needing a separate
mosaic for Mode7, and in the process I fixed that bug. The obvious
change is that the Chrono Trigger Mode7->Mode2 transition doesn't cause
the pendulum to jump anymore.
Windows were simplified just a tad. The range testing is shared for all
modes now. Ironically, it's a bit slower, but I'll take less code over
more speed for the accuracy core.
Speaking of speed, because there's so much less calculations per pixel
for BGs, performance for the entire emulator has gone up by 30% in the
accuracy core. Pretty neat overall, I can maintain 60fps in all but,
yeah you can guess can't you?
