Changelog:
- emulator/random: new array function with more realistic RAM
initializations
- emulator/random: both low and high entropy register initializations
now use PCG
- gba/player: rumble will time out and disable after being left on for
500ms; fixes Pokemon Pinball issue
- ruby/input/udev: fixed rumble effects [ma\_rysia]
- sfc/system: default to low-entropy randomization of memory
The low-entropy memory randomization is modeled after one of my SHVC
2/1/3 systems. It generates striped patterns in memory, using random
inputs (biased to 0x00/0xff), and has a random chance of corrupting 1-2
bits of random values in the pool of memory (to prevent easy emulator
detection and to match observed results on hardware.)
The reasoning for using PCG on register initializations, is that I don't
believe they're going to have repeating patterns like RAM does anyway.
And register initializations are way more vital.
I want to have the new low-entropy RAM mode tested, so at least for the
next few WIPs, I've set the SNES randomization over to low-entropy.
We'll have to have a long discussion and decide whether we want official
releases to use high-entropy or low-entropy.
Also, I figured out the cause of the Prince of Persia distortion ... I
had the volume under the audio settings tab set to 200%. I didn't
realize there were SNES games that clipped so easily, given how
incredibly weak SNES audio is compared to every other sound source on my
PC. So with no entropy or low-entropy, indeed the game now sounds just
fine.
I can't actually test the udev fixes, so I guess we'll see how that goes
for Screwtape and ma\_rysia.
I made a change to ruby/input/joypad/udev.cpp while diagnosing a problem
with higan's rumble behaviour on Linux, and accidentally committed it
in 15b3dc8b0b as part of a documentation
change.

Changelog:
- ruby: ported all remaining drivers to new API¹
- ruby/wasapi: fix for dropping one sample per period [SuperMikeMan]
- gb: emulated most of the TAMA RTC; but RTC state is still volatile²
¹: the new ports are:
- audio/{directsound, alsa, pulseaudio, pulseaudiosimple, ao}
- input/{udev, quartz, carbon}
It's pretty much guaranteed many of them will have compilation errors.
Please paste the error logs and I'll try to fix them up. It may take a
WIP or two to get there.
It's also possible things broke from the updates. If so, I could use
help comparing the old file to the new file, looking for mistakes, since
I can't test on these platforms apart from audio/directsound.
Please report working drivers in this list, so we can mark them off the
list. I'll need both macOS and Linux testers.
audio/directsound.cpp:112:
if(DirectSoundCreate(0, &_interface, 0) != DS_OK) return terminate(), false;
²: once I get this working, I'll add load/save support for the RTC
values. For now, the RTC data will be lost when you close the emulator.
Right now, you can set the date/time in real-time mode, and when you
start the game, the time will be correct, and the time will tick
forward. Note that it runs off emulated time instead of actual real
time, so if you fast-forward to 300%, one minute will be 20 seconds.
The really big limitation right now is that when you exit the game, and
restart it, and resume a new game, the hour spot gets corrupted, and
this seems to instantly kill your pet. Fun. This is crazy because the
commands the game sends to the TAMA interface are identical between
starting a new game and getting in-game versus loading a game.
It's likely going to require disassembling the game's code and seeing
what in the hell it's doing, but I am extremely bad at LR35092 assembly.
Hopefully endrift can help here :|

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.

I'm happy with where we are at with code cleanups and stability, so I'd
like to release v100. But even though I'm not assigning any special
significance to this version, we should probably test it more thoroughly
first.
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.
byuu says:
I'll post more detailed changes later, but basically:
- fixed Baldur's Gate bug
- guess if no flash ROM ID present (fixes Magical Vacation, many many
others)
- nall cleanups
- sfc/cartridge major cleanups
- bsxcartridge/"bsx" renamed to mcc/"mcc" after the logic chip it uses
(consistency with SGB/ICD2)
- ... and more!
byuu says:
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:
Windows port should run mostly well now, although exiting fullscreen
breaks the application in a really bizarre way. (clicking on the window
makes it sink to background rather than come to the foreground o_O)
I also need to add the doModalChange => audio.clear() thing for the
accursed menu stuttering with DirectSound.
I also finished porting all of the ruby drivers over to the newer API
changes from nall.
Since I can't compile the Linux or OS X drivers, I have no idea if there
are any typos that will result in compilation errors. If so, please let
me know where they're at and I'll try and fix them. If they're simple,
please try and fix them on your end to test further if you can.
I'm hopeful the udev crash will be gone now that nall::string checks for
null char* values passed to its stringify function. Of course, it's
a problem it's getting a null value in the first place, so it may not
work at all.
If you can compile on Linux (or by some miracle, OS X), please test each
video/audio/input driver if you don't mind, to make sure there's no
"compiles okay but still typos exist" bugs.
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:
This updates ruby to return shared_pointer<HID::Device> objects instead
of HID::Device* objects. It also fixes an ID bug where joypads were
starting at ID# 2+, but mice were also set to ID# 2. I also revised
nall/hid a lot, with getters and setters instead of stabbing at internal
state. I didn't yet patch nall::string to safely consume nullptr const
char* values, though.
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.
byuu says:
I've completely redone the ethos InputManager and ruby to work on
HID::Device objects instead of one giant scancode pool.
Currently only the udev driver supports the changes to ruby, so only
Linux users will be able to compile and run this WIP build.
The nice thing about the new system is that it's now possible to
uniquely identify controllers, so if you swap out gamepads, you won't
end up with it working but with all the mappings all screwed up. Since
higan lets you map multiple physical inputs to one emulated input, you
can now configure your keyboard and multiple gamepads to the same
emulated input, and then just use whatever controller you want.
Because USB gamepad makers failed to provide unique serial#s with each
controller, we have to limit the mapping to specific USB ports.
Otherwise, we couldn't distinguish two otherwise identical gamepads. So
basically your computer USB ports act like real game console input port
numbers. Which is kind of neat, I guess.
And the really nice thing about the new system is that we now have the
capability to support hotplugging input devices. I haven't yet added
this to any drivers, but I'm definitely going to add it to udev for v094
official.
Finally, with the device ID (vendor ID + product ID) exposed, we gain
one last really cool feature that we may be able to develop more in the
future. Say we created a joypad.bml file to include with higan. In it,
we'd store the Xbox 360 controller, and pre-defined button mappings for
each emulated system. So if higan detects you have an Xbox 360
controller, you can just plug it in and use it. Even better, we can
clearly specify the difference between triggers and analog axes, and
name each individual input. So you'd see "Xbox 360 Gamepad #1: Left
Trigger" instead of higan v093's "JP0::Axis2.Hi"
Note: for right now, ethos' input manager isn't filtering the device IDs
to look pretty. So you're going to see a 64-bit hex value for a device
ID right now instead of something like Joypad#N for now.

Changelog:
- GBA: SOUND_CTL_H is readable, fixes sound effects in Mario&Luigi
Superstar Saga [Cydrak] (note: game is still unplayable due to other
bugs)
- phoenix/Windows: workaround for Win32 API ListView bug, fixes slot
loading behavior
- ruby: added udev driver for Linux with rumble support, and added
rumble support to existing RawInput driver for XInput and DirectInput
- ethos: added new "Rumble" mapping to GBA input assignment, use it to
tell higan which controller to rumble (clear it to disable rumble)
- GBA: Game Boy Player rumble is now fully emulated
- core: added new normalized raw-color palette mode for Display
Emulation shaders
The way rumble was added to ethos was somewhat hackish. The support
doesn't really exist in nall.
I need to redesign the entire input system, but that's not a change
I want to make so close to a release.
