Update to v082r04 release.
byuu says:
So, here's the deal. I now have three emulators. I don't think the
NES/GB ones are at all useful, but I do want them to be eventually. And
having them have those pathetic little GUIs like ui-gameboy, and keeping
everything in separate project folders, just doesn't work well for me.
I kind of "got around" the issue with the Game Boy, by only allowing SGB
mode emulation. But there is no "Super Nintendo" ... er ... wait ...
uhmm ... well, you know what I mean anyway.
So, my idea is to write a multi-emulator GUI, and keep the projects
together. The GUI is not going to change much. The way I envision this
working:
At startup, you have a menubar with: "Cartridge, Settings, Tools, Help".
Cartridge has "Load NES Cartridge", "Load SNES Cartridge", etc.
When you load something, Cartridge is replaced with the appropriate
system menu, eg "SNES". Here you have all your regular items: "power,
reset, controller port selection, etc." There is also a new "Unload
Cartridge" option, which is how you restore the "Cartridge" menu again.
I have no plans to emulate any other systems, but if I ever do emulate
something that doesn't take cartridges, I'll change the name to just
"Load" or something.
The cheat editor / state manager will look and act exactly the same. The
settings panel will look exactly the same. I'll simply show/hide
system-specific options as needed, like NES/SNES aspect ratio
correction, etc. The input mapping window will just have settings for
the currently loaded system. Video and audio tweaking will apply
cross-system, as will hotkey mapping.
The GUI stuff is mostly copy-paste, so it should only take me a week to
get it 95% back to where it was, so don't worry, this isn't total GUI
rewrite #80.
I am, however, making all the objects pointers, so that I can destruct
them all prior to main() returning, which is certainly one way of fixing
that annoying Windows/Qt crash.
Please only test on Linux. The Windows port is broken to hell, and will
give you a bad impression of the idea:
- menu groups are not hiding for some reason (all groups are showing, it
looks hideous)
- Timer interval(0) is taking 16ms per call, capping the FPS to ~64 tops
[FWIW, bsnes/accuracy gets 130fps, bgameboy gets 450fps, bnes gets
800fps; all run at lowest possible granularity]
- the OS keeps beeping when you press keys (AGAIN)
Of course, Qt and GTK+ don't let you shrink a window from the requested
geometry size, because they suck. So the video scaling stuff doesn't
work all that great yet.
Man, a metric fuckton of things need to be fixed in phoenix, and
I really don't know how to fix any of them :/

Update to v088r08 release.
byuu says:
From this WIP, I'm starting on the impossible task of
a declarative-based GUI, which I'm calling Ethos.
base/ becomes emulator/, and we add emulator/interface.hpp, which is
a base API that all emulation cores must implement in full.
(Right now, it's kind of a hybrid to work with the old GUI and the new
GUI at the same time, of course.)
Unlike the old interfaces, the new base class also provides all general
usability hooks: loading and saving files and states, cheat codes, etc.
The new interface also contains information and vector structs to
describe all possible loading methods, controller bindings, etc; and
gives names for them all.
The actual GUI in fact should not include eg <gba/gba.hpp> anymore.
Should speed up GUI compilation.
So the idea going forward is that ethos will build a list of emulators
right when the application starts up.
Once you've appended an emulator to that list, you're done. No more GUI
changes are needed to support that system.
The GUI will have code to parse the emulator interfaces list, and build
all the requisite GUI options dynamically, declarative style.
Ultimately, once the project is finished, the new GUI should look ~99%
identical to the current GUI. But it'll probably be a whole lot smaller.

byuu says:
Added some more ARM opcodes, hooked up MMIO. Bind it with mmio[(addr
000-3ff)] = this; inside CPU/PPU/APU, goes to read(), write().
Also moved the Hitachi HG51B core to processor/, and split it apart from
the snes/chip/hitachidsp implementation.
This one actually worked really well. Very clean split between MMIO/DMA
and the processor core. I may move a more generic DMA function inside
the core, not sure yet.
I still believe the HG51B169 to be a variant of the HG51BS family, but
given they're meant to be incredibly flexible microcontrollers, it's
possible that each variant gets its own instruction set.
So, who knows. We'll worry about it if we ever find another HG51B DSP,
I guess.
GBA BIOS is constantly reading from 04000300, but it never writes. If
I return prng()&1, I can get it to proceed until it hits a bad opcode
(stc opcode, which the GBA lacks a coprocessor so ... bad codepath.)
Without it, it just reads that register forever and keeps resetting the
system, or something ...
I guess we're going to have to try and get ARMwrestler working, because
the BIOS seems to need too much emulation code to do anything at all.

This moves toward a profile-selection mode. Right now, it is incomplete.
There are three binaries, one for each profile. The GUI selection
doesn't actually do anything yet. There will be a launcher in a future
release that loads each profile's respective binary.
I reverted away from blargg's SMP library for the time being, in favor
of my own. This will fix most of the csnes/bsnes-performance bugs. This
causes a 10% speed hit on 64-bit platforms, and a 15% speed hit on
32-bit platforms. I hope to be able to regain that speed in the future,
I may also experiment with creating my own fast-SMP core which drops bus
hold delays and TEST register support (never used by anything, ever.)
Save states now work in all three cores, but they are not
cross-compatible. The profile name is stored in the description field of
the save states, and it won't load a state if the profile name doesn't
match.
The debugger only works on the research target for now. Give it time and
it will return for the other targets.
Other than that, let's please resume testing on all three once again.
See how far we get this time :)
I can confirm the following games have issues on the performance
profile:
- Armored Police Metal Jacket (minor logo flickering, not a big deal)
- Chou Aniki (won't start, so obviously unplayable)
- Robocop vs The Terminator (major in-game flickering, unplayable)
Anyone still have that gigantic bsnes thread archive from the ZSNES
forum? Maybe I posted about how to fix those two broken games in there,
heh.
I really want to release this as v1.0, but my better judgment says we
need to give it another week. Damn.

- SFC: performance profile removed
- SFC: code for handling non-threaded CPU, SMP, DSP, PPU removed
- SFC: Coprocessor, Controller (and expansion port) shared Thread code
merged to SFC::Cothread
- Cothread here just means "Thread with CPU affinity" (couldn't think
of a better name, sorry)
- SFC: CPU now has vector<Thread*> coprocessors, peripherals;
- this is the beginning of work to allow expansion port devices to be
dynamically changed at run-time
- ruby: all audio drivers default to 48000hz instead of 22050hz now if
no frequency is assigned
- note: the WASAPI driver can default to whatever the native frequency
is; doesn't have to be 48000hz
- tomoko: removed the ability to change the frequency from the UI (but
it will display the frequency used)
- tomoko: removed the timing settings panel
- the goal is to work toward smooth video via adaptive sync
- the model is broken by not being in control of the audio frequency
anyway
- it's further broken by PAL running at 50hz and WSC running at 75hz
- it was always broken anyway by SNES interlace timing varying from
progressive timing
- higan: audio/ stub created (for now, it's just nall/dsp/ moved here
and included as a header)
- higan: video/ stub created
- higan/GNUmakefile: now includes build rules for essential components
(libco, emulator, audio, video)
The audio changes are in preparation to merge wareya's awesome WASAPI
work without the need for the nall/dsp resampler.

Update to v098r03 release.

It took several hours, but I've rebuilt much of the SNES' bus memory
mapping architecture.
The new design unifies the cartridge string-based mapping
("00-3f,80-bf:8000-ffff") and internal bus.map calls. The map() function
now has an accompanying unmap() function, and instead of a fixed 256
callbacks, it'll scan to find the first available slot. unmap() will
free slots up when zero addresses reference a given slot.
The controllers and expansion port are now both entirely dynamic.
Instead of load/unload/power/reset, they only have the constructor
(power/reset/load) and destructor (unload). What this means is you can
now dynamically change even expansion port devices after the system is
loaded.
Note that this is incredibly dangerous and stupid, but ... oh well. The
whole point of this was for 21fx. There's no way to change the expansion
port device prior to loading a game, but if the 21fx isn't active, then
the reset vector hijack won't work. Now you can load a 21fx game, change
the expansion port device, and simply reset the system to active the
device.
The unification of design between controller port devices and expansion
port devices is nice, and overall this results in a reduction of code
(all of the Mapping stuff in Cartridge is gone, replaced with direct bus
mapping.) And there's always the potential to expand this system more in
the future now.
The big missing feature right now is the ability to push/pop mappings.
So if you look at how the 21fx does the reset vector, you might vomit
a little bit. But ... it works.
Also changed exit(0) to _exit(0) in the POSIX version of nall::execute.
[The _exit(0) thing is an attempt to make higan not crash when it tries
to launch icarus and it's not on $PATH. The theory is that higan forks,
then the child tries to exec icarus and fails, so it exits, all the
unique_ptrs clean up their resources and tell the X server to free
things the parent process is still using. Calling _exit() prevents
destructors from running, and seems to prevent the problem. -Ed.]

Since we're now talking about three splits, that's getting a bit out of
hand.
This WIP combines everything back into one project again. Added the
src/fast folder that has all the speed-oriented cores.
A slight slowdown to csnes from what it was before, I'm using blargg's
accurate DSP. I just don't like the idea of releasing a less accurate
DSP core than Snes9X v1.52 has. Plus the fast DSP core doesn't serialize
yet.
I moved back to snes_spc 0.9.0 because I care more about Tales and Star
Ocean than I do about Earthworm Jim 2. So if you try EWJ2 on csnes,
expect it to sound like it does on Snes9X. In other words, don't wear
headphones if you value your hearing.
The middle-of-the-road bsnes core uses blargg's accurate DSP, because
it's about 3% faster than mine which removes all of blargg's
optimizations. There is absolutely no accuracy loss here. bsnes v067.20
that is included should be equal to v067 official.
Performance:
Code:
asnes = 58fps
bsnes = 172fps +2.97x
csnes = 274fps +1.59x +4.72x
The binaries are not profiled, so that's an additional 15% slower from
the previous builds.
Save states only work on asnes, as I don't know how to serialize
blargg's cores yet. The copy_func thing is very confusing to me for some
reason. The debugger won't work anywhere.
Outside of that, please go ahead and bug test. Once I get the debugger
and save states working, I'll build some profiled v1.0 releases for all
three, and we can test that for a bit and then release.

destructors from running, and seems to prevent the problem. -Ed.]

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.

Update to v098r01 release.

Changelog:
- SFC: balanced profile removed
- SFC: performance profile removed
- SFC: code for handling non-threaded CPU, SMP, DSP, PPU removed
- SFC: Coprocessor, Controller (and expansion port) shared Thread code
merged to SFC::Cothread
- Cothread here just means "Thread with CPU affinity" (couldn't think
of a better name, sorry)
- SFC: CPU now has vector<Thread*> coprocessors, peripherals;
- this is the beginning of work to allow expansion port devices to be
dynamically changed at run-time
- ruby: all audio drivers default to 48000hz instead of 22050hz now if
no frequency is assigned
- note: the WASAPI driver can default to whatever the native frequency
is; doesn't have to be 48000hz
- tomoko: removed the ability to change the frequency from the UI (but
it will display the frequency used)
- tomoko: removed the timing settings panel
- the goal is to work toward smooth video via adaptive sync
- the model is broken by not being in control of the audio frequency
anyway
- it's further broken by PAL running at 50hz and WSC running at 75hz
- it was always broken anyway by SNES interlace timing varying from
progressive timing
- higan: audio/ stub created (for now, it's just nall/dsp/ moved here
and included as a header)
- higan: video/ stub created
- higan/GNUmakefile: now includes build rules for essential components
(libco, emulator, audio, video)
The audio changes are in preparation to merge wareya's awesome WASAPI
work without the need for the nall/dsp resampler.
