Changelog:
- massive cleanups and optimizations on the PPU core
- ~9% speedup over v099 official
This is pretty much it for the low-hanging fruit of speeding up higan. Any
more gains from this point will be extremely hard-fought, unfortunately.
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.

Got it. Wow, that didn't hurt nearly as much as I thought it was going
to.
Dropped from 127.5fps to 123.5fps to use Natural/Integer for
(u)int(8,16,32,64).
That's totally worth the cost.

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

Changelog:
- restructured the project and removed a whole bunch of old/dead
directives from higan/GNUmakefile
- huge amounts of work on hiro/cocoa (compiles but ~70% of the
functionality is commented out)
- fixed a masking error in my ARM CPU disassembler [Lioncash]
- SFC: decided to change board cic=(411,413) back to board
region=(ntsc,pal) ... the former was too obtuse
If you rename Boolean (it's a problem with an include from ruby, not
from hiro) and disable all the ruby drivers, you can compile an
OS X binary, but obviously it's not going to do anything.
It's a boring WIP, I just wanted to push out the project structure
change now at the start of this WIP cycle.
byuu says:
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.

This will be another massive diff from the previous version.
All of higan was updated to use the new foo& bar syntax, and I also
updated switch statements to be consistent as well (but not in the
disassemblers, was starting to get an RSI just from what I already did.)
phoenix/{windows, cocoa, qt} need to be updated to use "string foo"
instead of "const string& foo", and after that, the major diffs should
be finished.
This archive is the first time I'm posting my copy-on-write,
size+capacity nall::string class, so any feedback on that is welcome as
well.

Changelog:
- merged AWJ's hires color blending improvements (most notably: fixes
Marvelous' text)
- created sfc/base/ to store base unit (expansion port device) emulation
- synchronized the markup of Satellaview and Sufami Turbo cartridge
slots in the board markup
- fixed "Initializing ..." typo in timing settings
If at all possible, I'd really like to have heavy testing of games that
use hires graphics to check for any regressions.
I trust AWJ's code, and all of the test ROMs I have thrown at it all
appear to work great. But better safe than sorry. Same deal for any core
changes, it's a lot better to catch it now than after v093 is released.
byuu says:
Basically just a project rename, with s/bsnes/higan and the new icon
from lowkee added in.
It won't compile on Windows because I forgot to update the resource.rc
file, and a path transform command isn't working on Windows.
It was really just meant as a starting point, so that v091 WIPs can flow
starting from .00 with the new name (it overshadows bsnes v091, so
publicly speaking this "shouldn't exist" and will probably be deleted
from Google Code when v092 is ready.)
