I added (imperfect) memory conflict timing to the SA1.
Before:
- WRAM↔↔ROM ran 7% too fast
- ROM↔↔ROM ran 100% too fast
- WRAM↔↔IRAM ran 7% too fast
- ROM↔↔IRAM ran 7% too fast
- IRAM↔↔IRAM ran 287% too fast
- BWRAM↔↔BWRAM ran 100% too fast
- HDMA ROM↔↔ROM ran 15% too fast
- HDMA WRAM↔↔ROM ran 15% too fast
- DMA ROM↔↔ROM ran 100% too fast
After:
- ROM↔↔ROM runs 14% too fast
- HDMA WRAM↔↔ROM runs 7% too fast
- DMA ROM↔↔ROM runs 4% too fast
If you enable this with the fast PPU + DSP, your framerate in SA1 games
will drop by 51%. And even if you disable it, you'll still lose 9% speed
in SA1 games, and 2% speed in non-SA1 games, because of changes needed
to make this support possible.
By default, I'm leaving this off. Compile with `-DACCURATE_SA1` (or
uncomment the line in sfc/sfc.hpp) if you want to try it out.
This'll almost certainly cause some SA1 regressions, so I guess we'll
tackle those as they arise.

can now be triggered without focus as well
- hiro/cocoa: fix crash on exit from menu [ncbncb]
- ruby: smarter `double` → `int16_t` conversion to prevent
underflow/overflow
byuu says:
Changelog:
- ruby: rewrote the API interfaces for Video, Audio, Input
- ruby/audio: can now select the number of output channels (not useful
to higan, sorry)
- ruby/asio: various improvements
- tomoko: audio settings panel can now select separate audio devices
(for ASIO, OSS so far)
- tomoko: audio settings panel frequency and latency lists are
dynamically populated now
Note: due to the ruby API rewrite, most drivers will not compile. Right
now, the following work:
- video: Direct3D, XShm
- audio: ASIO, OSS
- input: Windows, SDL, Xlib
It takes a really long time to rewrite these (six hours to do the
above), so it's going to be a while before we're back at 100%
functionality again.
Errata:
- ASIO needs device(), setDevice()
- need to call setDevice() at program startup to populate
frequency/latency settings properly
- changing the device and/or frequency needs to update the emulator
resampler rates
The really hard part is going to be the last one: the only way to change
the emulator frequency is to flush all the audio streams and then
recompute all the coefficients for the resamplers. If this is called
during emulation, all audio streams will be erased and thus no sound
will be output. I'll most likely be forced to simply ignore
device/frequency changes until the user loads another game. It is at
least possible to toggle the latency dynamically.
r13 and r14 weren't posted as individual releases, but their changelogs
were posted.
byuu says about r13:
I'm not going to be posting WIPs for r13 and above for a while.
The reason is that I'm working on the major manifest overhaul I've
discussed previously on the icarus subforum.
I'm recreating my boards database from scratch using the map files
and the new map analyzer. The only games that will load are ones
I've created board definitions for, and updated
sfc/cartridge/markup.cpp to parse. Once I've finished all the
boards, then I'll update the heuristics.
Then finally, I'll sync the syntax changes over to the fc, gb, gba
cores.
Once that's done, I'll start posting WIPs again, along with a new
build of icarus.
But I'll still post changelogs as I work through things.
Changelog (r13):
- preservation: created new database-builder tool (merges
region-specific databases with boards)
- icarus: support new, external database format
(~/.config/icarus/Database/(Super Famicom.bml, ...)
- added 1A3B-(10,11,12); 1A3B-20
byuu says about r14:
r14 work:
I successfully created mappings for every board used in the US set.
I also updated icarus' heuristics to use the new mappings, and
created ones there for the boards that are only in the JP set.
Then I patched icarus to support pulling games out of the database
when it's used on a game folder to generate a manifest file.
Then I updated a lot of code in higan/sfc to support the new mapping
syntax. sfc/cartridge/markup.cpp is about half the size it used to
be with the new mappings, and I was able to kill off both map/id and
map/select entirely.
Then I updated all four emulated systems (and both subsystems) to
use "board" as the root node, and harmonized their syntax (made them
all more consistent with each other.)
Then I added a manifest viewer to the tools window+menu. It's kind
of an advanced user feature, but oh well. No reason to coddle people
when the feature is very useful for developers. The viewer will show
all manifests in order when you load multi-cart games as well.
Still not going to call any syntax 100% done right now, but
thankfully with the new manifest-free folders, nobody will have to
do anything to use the new format. Just download the new version and
go.
The Super Famicom Event stuff is currently broken (CC92/PF94
boards). That's gonna be fun to support.
byuu says about r15:
EDIT: small bug in icarus with heuristics. Edit
core/super-famicom.cpp line 27:
if(/*auto*/ markup = cartridge.markup) {
Gotta remove that "auto" so that it returns valid markup.
Resolved the final concerns I had with the new manifest format.
Right now there are two things that are definitely broken: MCC (BS-X
Town cart) and Event (CC '92 and PF'94).
And there are a few things that are untested: SPC7110, EpsonRTC,
SharpRTC, SDD1+RAM, SufamiTurbo, BS-X slotted carts.

This WIP substantially restructures the ruby API for the first time
since that project started.
It is my hope that with this restructuring, destruction of the ruby
objects should now be deterministic, which should fix the crashing on
closing the emulator on Linux. We'll see I guess ... either way, it
removed two layers of wrappers from ruby, so it's a pretty nice code
cleanup.
It won't compile on Windows due to a few issues I didn't see until
uploading the WIP, too lazy to upload another. But I fixed all the
compilation issues locally, so it'll work on Windows again with the next
WIP (unless I break something else.)
(Kind of annoying that Linux defines glActiveTexture but Windows
doesn't.)
byuu says:
Finally!! Compilation works once again on Windows.
However, it's pretty buggy. Modality isn't really working right, you can
still poke at other windows, but when you select ListView items, they
redraw as empty boxes (need to process WM_DRAWITEM before checking
modality.)
The program crashes when you close it (probably a ruby driver's term()
function, that's what it usually is.)
The Layout::setEnabled(false) call isn't working right, so you get that
annoying chiming sound and cursor movement when mapping keyboard keys to
game inputs.
The column sizing seems off a bit on first display for the Hotkeys tab.
And probably lots more.
byuu says:
Changelog:
* added driver selection
* added video scale + aspect correction settings
* added A/V sync + audio mute settings
* added configuration file
* fixed compilation bugs under Windows and Linux
* fixed window sizing
* removed HSU1
* the system menu stays as "System", because "Game Boy Advance" was too
long a string for the smallest scale size
* some more stuff
You guys probably won't be ecstatic about the video sizing options, but
it's basically your choice of 1x, 2x or 4x scale with optional aspect
correction. 3x was intentionally skipped because it looks horrible on
hires SNES games. The window is resized and recentered upon loading
games. The window doesn't resize otherwise. I never really liked the way
v094 always left you with black screen areas and left you with
off-centered window positions.
I might go ahead and add the pseudo-fullscreen toggle that will jump
into 4x mode (respecting your aspect setting.)
Short-term:
* add input port changing support
* add other input types (mouse-based, etc)
* add save states
* add cheat codes
* add timing configuration (video/audio sync)
* add hotkeys (single state)
We can probably do a new release once the short-term items are
completed.
Long-term:
* add slotted cart loader (SGB, BSX, ST)
* add DIP switch selection window (NSS)
* add cheat code database
* add state manager
* add overscan masking
Not planned:
* video color adjustments (will allow emulated color vs raw color; but
no more sliders)
* pixel shaders
* ananke integration (will need to make a command-line version to get my
games in)
* fancy audio adjustment controls (resampler, latency, volume)
* input focus settings
* relocating game library (not hard, just don't feel like it)
* localization support (not enough users)
* window geometry memory
* anything else not in higan v094

byuu says:
Not an official WIP (a WIP WIP? A meta-WIP?), just throwing in the new
fullscreen code, and I noticed that OpenGL colors in 30-bit mode are all
fucked up now for some strange reason. So I'm just using this snapshot
to debug the issue.
