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 v096r07 release.

Changelog:
- configuration files are now stored in localpath() instead of configpath()
- Video gamma/saturation/luminance sliders are gone now, sorry
- added Video Filter->Blur Emulation [1]
- added Video Filter->Scanline Emulation [2]
- improvements to GBA audio emulation (fixes Minish Cap) [Jonas Quinn]
[1] For the Famicom, this does nothing. For the Super Famicom, this
performs horizontal blending for proper pseudo-hires translucency. For
the Game Boy, Game Boy Color, and Game Boy Advance, this performs
interframe blending (each frame is the average of the current and
previous frame), which is important for things like the GBVideoPlayer.
[2] Right now, this only applies to the Super Famicom, but it'll come to
the Famicom in the future. For the Super Famicom, this option doesn't
just add scanlines, it simulates the phosphor decay that's visible in
interlace mode. If you observe an interlaced game like RPM Racing on
a real SNES, you'll notice that even on perfectly still screens, the
image appears to shake. This option emulates that effect.
Note 1: the buffering right now is a little sub-optimal, so there will
be a slight speed hit with this new support. Since the core is now
generating native ARGB8888 colors, it might as well call out to the
interface to lock/unlock/refresh the video, that way it can render
directly to the screen. Although ... that might not be such a hot idea,
since the GBx interframe blending reads from the target buffer, and that
tends to be a catastrophic option for performance.
Note 2: the balanced and performance profiles for the SNES are
completely busted again. This WIP took 6 1/2 hours, and I'm exhausted.
Very much not looking forward to working on those, since those two have
all kinds of fucked up speedup tricks for non-interlaced and/or
non-hires video modes.
Note 3: if you're on Windows and you saved your system folders somewhere
else, now'd be a good time to move them to %localappdata%/higan

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?

Update to v095r05 release.
byuu says:
Changelog:
- GBA: lots of emulation improvements
- PPU PRAM is 16-bits wide
- DMA masks &~1/Half, &~3/Word
- VRAM OBJ 8-bit writes are ignored
- OAM 8-bit writes are ignored
- BGnCNT unused bits are writable*
- BG(0,1)CNT can't set the d13
- BLDALPHA is readable (fixes Donkey Kong Country, etc)
- SNES: lots of code cleanups
- sfc/chip => sfc/coprocessor
- UI: save most recent controller selection
GBA test scores: 1552/1552, 37/38, 1020/1260
(* forgot to add the value to the read function, so endrift's I/O tests
for them will fail. Fixed locally.)
Note: SNES is the only system with multiple controller/expansion port
options, and as such is the only one with a "None" option. Because it's
shared by the controller and expansion port, it ends up sorted first in
the list. This means that on your first run, you'll need to go to Super
Famicom->Controller Port 1 and select "Gamepad", otherwise input won't
work.
Also note that changing the expansion port device requires loading a new
cart. Unlike controllers, you aren't meant to hotplug expansion port
devices.
