Nothing WS-related this time.
First, I fixed expansion port device mapping. On first load, it was
mapping the expansion port device too late, so it ended up not taking
effect. I had to spin out the logic for that into
Program::connectDevices(). This was proving to be quite annoying while
testing eBoot (SNES-Hook simulation.)
Second, I fixed the audio->set(Frequency, Latency) functions to take
(uint) parameters from the configuration file, so the weird behavior
around changing settings in the audio panel should hopefully be gone
now.
Third, I rewrote the interface->load,unload functions to call into the
(Emulator)::System::load,unload functions. And I have those call out to
Cartridge::load,unload. Before, this was inverted, and Cartridge::load()
was invoking System::load(), which I felt was kind of backward.
The Super Game Boy really didn't like this change, however. And it took
me a few hours to power through it. Before, I had the Game Boy core
dummying out all the interface->(load,save)Request calls, and having the
SNES core make them for it. This is because the folder paths and IDs
will be different between the two cores.
I've redesigned things so that ICD2's Emulator::Interface overloads
loadRequest and saveRequest, and translates the requests into new
requests for the SuperFamicom core. This allows the Game Boy code to do
its own loading for everything without a bunch of Super Game Boy special
casing, and without any awkwardness around powering on with no cartridge
inserted.
This also lets the SNES side of things simply call into higher-level
GameBoy::interface->load,save(id, stream) functions instead of stabbing
at the raw underlying state inside of various Game Boy core emulation
classes. So things are a lot better abstracted now.

More V30MZ implemented, a lot more to go.
icarus now supports importing WS and WSC games. It expects them to have
the correct file extension, same for GB and GBC.
> Ugh, apparently HiDPI icarus doesn't let you press the check boxes.
I set the flag value in the plist to false for now. Forgot to do it for
higan, but hopefully I won't forget before release.

A minor WIP to get us started.
Changelog:
- System::Video merged to PPU::Video
- System::Audio merged to DSP::Audio
- System::Configuration merged to Interface::Settings
- created emulator/emulator.cpp and accompanying object file for shared
code between all cores
Currently, emulator.cpp just holds a videoColor() function that takes
R16G16B16, performs gamma/saturation/luma adjust, and outputs
(currently) A8R8G8B8. It's basically an internal function call for cores
to use when generating palette entries. This code used to exist inside
ui-tomoko/program/interface.cpp, but we have to move it internal for
software display emulation. But in the future, we could add other useful
cross-core functionality here.
byuu says:
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:
- fixed S-DD1 RAM writes (Star Ocean audio fixed)
- applied all of the DMG test ROM fixes discussed earlier; passes many
more test ROMs now
- at least until the GBVideoPlayer is working: for debugging purposes,
CPU/PPU single-step now instead of sync just-in-time (~30% slower)
- fixed OS X crash on NSTextView (hopefully, would be very odd if not)
Unfortunately passing these test ROMs caused my favorite GB/GBC game to
break all of its graphics =(
Shin Megami Tensei - Devichil - Kuro no Sho (Japan) is all garbled now.
I'm really quite bummed by this ... but I guess I'll go through and
revert r04's fixes one at a time until I find what's causing it.
On the plus side, Astro Rabby is playable now. Still acts weird when
pressing B/A on the first screen, but the start button will start the
game.
EDIT: got it. Shin Megami Tensei - Devichil requires FF4F (VBK) to be
readable. Before, it was always returning 0x00. With my return 0xFF
patch, that broke. But it should be returning the VBK value, which also
fixes it. Also need to handle FF68/FF6A reads. Was really hoping that'd
help GBVideoPlayer too, but nope. It doesn't read any of those three
registers.
byuu says:
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.
byuu says:
Changelog:
- fixed cartridge load window focus on Windows
- lots of updates to nall, ruby and phoenix
- ethos and Emulator::Interface updated from "foo &bar" to "foo& bar"
syntax (work-in-progress)
Before I had mixed the two ways to declare variables/arguments all over
the place, so the goal is to unify them all for consistency. So the
changelog for this release will be massive (750KB >.>) due to the syntax
change. Yeah, that's what I spent the last three days working on ...
byuu says:
higan changelog:
- compiler is set to g++-4.7, subst(cc,++) rule is gone, C files compile
with $(compiler) -x c
- make throws an error when you specify an invalid profile or compile on
an unsupported platform (instead of hanging forever)
- added unverified.png to resources (causes too big of a speed hit to
actually check for folder/unverified file ... so disabled for now)
- fixed default browser paths for Game Boy, Sufami Turbo and BS-X
Satellaview (have to delete paths.cfg to see this)
- browser home button seeks to configpath()/higan/library.cfg
- settings->driver is now settings->advanced, and it adds game library
path setting and profile information
- emulation cores now load manifest files internally, manifest.bml is
not required for a game folder to be recognized by higan as such
- BS-X Satellaview and Sufami Turbo slot cartridge handling moved out of
sfc/chip and into sfc/slot
- Video::StartFullScreen only sets fullscreen when a game is specified
on the command-line
purify and ananke changelog:
- library output path shown in purify window
- added button to change library path
- squelch firmware warning windows to prevent multi-threading crash, but
only via purify (they show up in higan still)
In the release thread, byuu says:
The first official release of higan has been posted. higan is the
new name for bsnes, and it continues with the latter's version
numbering.
Note that as of now, bsnes still exists. It's a module distributed
inside of higan. bsnes is now specific to my SNES emulator.
Due to last minute changes to the emulator interface, and missing
support in ananke, I wasn't able to include Cydrak's Nintendo DS
emulator dasShiny in this build, but I hope to do so in the next
release.

For both new and experienced users, please read the higan user guide
first:
http://byuu.org/higan/user-guide
In the v091 WIP thread, byuu says:
r15->r16:
- BS-X MaskROM handling (partial ... need to split bsx/flash away
from sfc/chip, restructure code - it requires tagging the base
cart markup for now, but it needs to parse the slotted cart
markup)
- phoenixflags / phoenixlink += -m32
- nall/sort stability
- if(input.poll(scancode[activeScancode]) == false) return;
- MSU1 / USART need to use interface->path(1)
- MSU1 needs to use Markup::Document, not XML::Document
- case-insensitive folder listings
- remove nall/emulation/system.hpp files (move to ananke)
- remove rom/ram id= checks with indexing
X have cores ask for manifest.bml (skipped for v092's release, too
big a change)
- rename compatibility profile to balanced (so people don't assume
it has better compatibility than accuracy)
byuu says:
higan changelog:
- generates title displayed in emulator window by asking the core
- core builds title solely from "information/title" ... if it's not
there, you don't get a title at all
- sub-system load menu is gone ... since there are multiple revisions of
the SGB, this never really worked well anyway
- to load an SGB, BS-X or ST cartridge, load the base cartridge first
- "File->Load Game" moved to "Load->Import Game" ... may cause a bit of
confusion to new users, but I don't like having a single-item menu,
we'll just have to explain it to new users
- browser window redone to look like ananke
- home button here goes to ~/Emulation rather than just ~ like ananke,
since this is the home of game folders
- game folder icon is now the executable icon for the Tango theme
(orange diamond), meant to represent a complete game rather than
a game file or archive
ananke changelog:
- outputs GBC games to "Game Boy Color/" instead of "Game Boy/"
- adds the file basename to "information/title"
Known issues:
- using ananke to load a GB game trips the Super Famicom SGB mode and
fails (need to make the full-path auto-detection ignore non-bootable
systems)
- need to dump and test some BS-X media before releasing
- ananke lacks BS-X Satellaview cartridge support
- v092 isn't going to let you retarget the ananke/higan game folder path
of ~/Emulation, you will have to wait for a future version if that
bothers you so greatly
[Later, after the v092 release, byuu posted this additional changelog:
- kill laevateinn
- add title()
- add bootable, remove load
- combine file, library
- combine [][][] paths
- fix SFC subtype handling XML->BML
- update file browser to use buttons
- update file browser keyboard handling
- update system XML->BML
- fix sufami turbo hashing
- remove Cartridge::manifest
]
byuu says (about higan):
- dropped release/ root node for individual games (still there in
ananke's database.)
- Memory export uses smarter names (vram.rwm -> video.ram, etc.)
- cheat database moved from XML to BML (3.1MB to 1.9MB file size.)
- cheat codes moved from XML to BML
- resource manifest moved from XML to BML
What can I say, I like consistency. But I'll leave the shaders alone
until I get around to shader folders.
byuu says (about ananke):
Works with higan v091r13. Only does SNES stuff so far.
[r07 and r08 were not posted to the WIP thread. -Ed.]
byuu says:
I'd appreciate it if you guys wouldn't mind testing out the database
functionality.
Save this file as database.bml (remove the date) inside
~/.config/higan/Super Famicom.sfc/ or %APPDATA%/higan/Super Famicom.sfc/
http://byuu.org/snes/database/database_2012-10-21.bml
Now load any of the 20 games in the database from the file dialog. They
need to be named *.sfc, have no copier header, and have firmware
appended (for Mario Kart only so far.)
If anyone actually does test it, please let me know how it goes for you
and what you think. Note that future versions of higan will have the
database.bml file included with the release.
[No prior releases were posted to the WIP thread. -Ed.]

Super Famicom mapping system has been reworked as discussed with the
mask= changes. offset becomes base, mode is gone. Also added support for
comma-separated fields in the address fields, to reduce the number of
map lines needed.
<?xml version="1.0" encoding="UTF-8"?>
<cartridge region="NTSC">
<superfx revision="2">
<rom name="program.rom" size="0x200000"/>
<ram name="save.rwm" size="0x8000"/>
<map id="io" address="00-3f,80-bf:3000-32ff"/>
<map id="rom" address="00-3f:8000-ffff" mask="0x8000"/>
<map id="rom" address="40-5f:0000-ffff"/>
<map id="ram" address="00-3f,80-bf:6000-7fff" size="0x2000"/>
<map id="ram" address="70-71:0000-ffff"/>
</superfx>
</cartridge>
Or in BML:
cartridge region=NTSC
superfx revision=2
rom name=program.rom size=0x200000
ram name=save.rwm size=0x8000
map id=io address=00-3f,80-bf:3000-32ff
map id=rom address=00-3f:8000-ffff mask=0x8000
map id=rom address=40-5f:0000-ffff
map id=ram address=00-3f,80-bf:6000-7fff size=0x2000
map id=ram address=70-71:0000-ffff
As a result of the changes, old mappings will no longer work. The above
XML example will run Super Mario World 2: Yoshi's Island. Otherwise,
you'll have to write your own.
All that's left now is to work some sort of database mapping system in,
so I can start dumping carts en masse.
The NES changes that FitzRoy asked for are mostly in as well.
Also, part of the reason I haven't released a WIP ... but fuck it, I'm
not going to wait forever to post a new WIP.
I've added a skeleton driver to emulate Campus Challenge '92 and
Powerfest '94. There's no actual emulation, except for the stuff I can
glean from looking at the pictures of the board. It has a DSP-1 (so
SR/DR registers), four ROMs that map in and out, RAM, etc.
I've also added preliminary mapping to upload high scores to a website,
but obviously I need the ROMs first.
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.)
