Update to v103r10 release.
byuu says:
Changelog:
- tomoko: video scaling options are now resolutions in the
configuration file, eg "640x480", "960x720", "1280x960"
- tomoko: main window is now always resizable instead of fixed width
(also supports maximizing)
- tomoko: added support for non-integral scaling in windowed mode
- tomoko: made the quick/managed state messaging more consistent
- tomoko: hide "Find Codes ..." button from the cheat editor window if
the cheat database is not present
- tomoko: per-game cheats.bml file now goes into the higan/ subfolder
instead of the root folder
So the way the new video system works is you have the following options
on the video settings panel:
Windowed mode: { Aspect correction, Integral scaling, Adaptive }
Fullscreen mode: { Aspect correction, Integral scaling } (and one day,
hopefully Exclusive will be added here)
Whenever you adjust the overscan masking, or you change any of the
windowed or fullscreen mode settings, or you choose a different video
scale from the main menu, or you load a new game, or you unload a game,
or you rotate the display of an emulated system, the resizeViewport
logic will be invoked. This logic will remember the last option you
chose for video scale, and base the new window size on that value as an
upper limit of the new window size.
If you are in windowed mode and have adaptive enabled, it will shrink
the window to fit the contents of the emulated system's video output.
Otherwise, if you are not in integral scaling mode, it will scale the
video as large as possible to fit into the video scaled size you have
selected. Otherwise, it will perform an integral scale and center the
video inside of the viewport.
If you are in fullscreen mode, it's much the same, only there is no
adaptive mode.
A major problem with Xorg is that it's basically impossible to change
the resizability attribute of a window post-creation. You can do it, but
all kinds of crazy issues start popping up. Like if you toggle
fullscreen, then you'll find that the window won't grow past a certain
fairly small size that it's already at, and cannot be shrunk. And the
multipliers will stop expanding the window as large as they should. And
sometimes the UI elements won't be placed in the correct position, or
the video will draw over them. It's a big mess. So I have to keep the
main window always resizable. Also, note that this is not a limitation
of hiro. It's just totally broken in Xorg itself. No amount of fiddling
has ever allowed this to work reliably for me on either GTK+ 2 or Qt 4.
So what this means is ... the adaptive mode window is also resizable.
What happens here is, whenever you drag the corners of the main window
to resize it, or toggle the maximize window button, higan will bypass
the video scale resizing code and instead act as though the adaptive
scaling mode were disabled. So if integral scaling is checked, it'll
begin scaling in integral mode. Otherwise, it'll begin scaling in
non-integral mode.
And because of this flexibility, it no longer made sense for the video
scale menu to be a radio box. I know, it sucks to not see what the
active selection is anymore, but ... say you set the scale to small,
then you accidentally resized the window a little, but want it snapped
back to the proper small resolution dimensions. If it were a radio item,
you couldn't reselect the same option again, because it's already active
and events don't propagate in said case. By turning them into regular
menu options, the video scale menu can be used to restore window sizing.
Errata:
On Windows, the main window blinks a few times on first load. The fix
for that is a safeguard in the video settings code, roughly like so ...
but note you'd need to make a few other changes for this to work against
v103r10:
auto VideoSettings::updateViewport(bool firstRun) -> void {
settings["Video/Overscan/Horizontal"].setValue(horizontalMaskSlider.position());
settings["Video/Overscan/Vertical"].setValue(verticalMaskSlider.position());
settings["Video/Windowed/AspectCorrection"].setValue(windowedModeAspectCorrection.checked());
settings["Video/Windowed/IntegralScaling"].setValue(windowedModeIntegralScaling.checked());
settings["Video/Windowed/AdaptiveSizing"].setValue(windowedModeAdaptiveSizing.checked());
settings["Video/Fullscreen/AspectCorrection"].setValue(fullscreenModeAspectCorrection.checked());
settings["Video/Fullscreen/IntegralScaling"].setValue(fullscreenModeIntegralScaling.checked());
horizontalMaskValue.setText({horizontalMaskSlider.position()});
verticalMaskValue.setText({verticalMaskSlider.position()});
if(!firstRun) presentation->resizeViewport();
}
That'll get it down to one blink, as with v103 official. Not sure I can
eliminate that one extra blink.
I forgot to remove the setResizable toggle on fullscreen mode exit. On
Windows, the main window will end up unresizable after toggling
fullscreen. I missed that one because like I said, toggling resizability
is totally broken on Xorg. You can fix that with the below change:
auto Presentation::toggleFullScreen() -> void {
if(!fullScreen()) {
menuBar.setVisible(false);
statusBar.setVisible(false);
//setResizable(true);
setFullScreen(true);
if(!input->acquired()) input->acquire();
} else {
if(input->acquired()) input->release();
setFullScreen(false);
//setResizable(false);
menuBar.setVisible(true);
statusBar.setVisible(settings["UserInterface/ShowStatusBar"].boolean());
}
resizeViewport();
}
Windows is stealing focus on calls to resizeViewport(), so we need to
deal with that somehow ...
I'm not really concerned about the behavior of shrinking the viewport
below the smallest multiplier for a given system. It might make sense to
snap it to the window size and forego all other scaling, but honestly
... meh. I don't really care. Nobody sane is going to play like that.

Update to v103r08 release.
byuu says:
Changelog:
- emulator: improved aspect correction accuracy by using
floating-point calculations
- emulator: added videoCrop() function, extended videoSize() to take
cropping parameters¹
- tomoko: the overscan masking function will now actually resize the
viewport²
- gba/cpu: fixed two-cycle delay on triggering DMAs; not running DMAs
when the CPU is stopped
- md/vdp: center video when overscan is disabled
- pce/vce: resize video output from 1140x240 to 1120x240
- tomoko: resize window scaling from 326x240 to 320x240
- tomoko: changed save slot naming and status bar messages to indicate
quick states vs managed states
- tomoko: added increment/decrement quick state hotkeys
- tomoko: save/load quick state hotkeys now save to slots 1-5 instead
of always to 0
- tomoko: increased overscan range from 0-16 to 0-24 (in case you want
to mask the Master System to 240x192)
¹: the idea here was to decouple raw pixels from overscan masking.
Overscan was actually horrifically broken before. The Famicom outputs at
256x240, the Super Famicom at 512x480, and the Mega Drive at 1280x480.
Before, a horizontal overscan mask of 8 would not reduce the Super
Famicom or Mega Drive by nearly as much as the Famicom. WIth the new
videoCrop() function, the internals of pixel size distortions can be
handled by each individual core.
²: furthermore, by taking optional cropping information in
videoSize(), games can scale even larger into the viewport window. So
for example, before the Super Famicom could only scale to 1536x1440. But
by cropping the vertical resolution by 6 (228p effectively, still more
than NTSC can even show), I can now scale to 1792x1596. And wiht aspect
correction, that becomes a perfect 8:7 ratio of 2048x1596, giving me
perfectly crisp pixels without linear interpolation being required.
Errata: for some reason, when I save a new managed state with the SFC
core, the default description is being set to a string of what looks to
be hex numbers. I found the cause ... I'll fix this in the next release.
Note: I'd also like to hide the "find codes..." button if cheats.bml
isn't present, as well as update the SMP TEST register comment from
smp/timing.cpp

Update to v100r16 release.
byuu says: (Windows users may need to include <sys/time.h> at the top of nall/chrono.hpp, not sure.) Unchangelog: - forgot to add the Scheduler clock=0 fix because I have the memory of a goldfish Changelog: - new icarus database with nine additional games - hiro(GTK,Qt) won't constantly write its settings.bml file to disk anymore - added latency simulator for fun (settings.bml => Input/Latency in milliseconds) So the last one ... I wanted to test out nall::chrono, and I was also thinking that by polling every emulated frame, it's pretty wasteful when you are using Fast Forward and hitting 200+fps. As I've said before, calls to ruby::input::poll are not cheap. So to get around this, I added a limiter so that if you called the hardware poll function within N milliseconds, it'll return without doing any actual work. And indeed, that increases my framerate of Zelda 3 uncapped from 133fps to 142fps. Yay. But it's not a "real" speedup, as it only helps you when you exceed 100% speed (theoretically, you'd need to crack 300% speed since the game itself will poll at 16ms at 100% speed, but yet it sped up Zelda 3, so who am I to complain?) I threw the latency value into the settings file. It should be 16, but I set it to 5 since that was the lowest before it started negatively impacting uncapped speeds. You're wasting your time and CPU cycles setting it lower than 5, but if people like placebo effects it might work. Maybe I should let it be a signed integer so people can set it to -16 and think it's actually faster :P (I'm only joking. I took out the 96000hz audio placebo effect as well. Not really into psychological tricks anymore.) But yeah seriously, I didn't do this to start this discussion again for the billionth time. Please don't go there. And please don't tell me this WIP has higher/lower latency than before. I don't want to hear it. The only reason I bring it up is for the fun part that is worth discussing: put up or shut up time on how sensitive you are to latency! You can set the value above 5 to see how games feel. I personally can't really tell a difference until about 50. And I can't be 100% confident it's worse until about 75. But ... when I set it to 150, games become "extra difficult" ... the higher it goes, the worse it gets :D For this WIP, I've left no upper limit cap. I'll probably set a cap of something like 500ms or 1000ms for the official release. Need to balance user error/trolling with enjoyability. I'll think about it. [...] Now, what I worry about is stupid people seeing it and thinking it's an "added latency" setting, as if anyone would intentionally make things worse by default. This is a limiter. So if 5ms have passed since the game last polled, and that will be the case 99.9% of the time in games, the next poll will happen just in time, immediately when the game polls the inputs. Thus, a value below 1/<framerate>ms is not only pointless, if you go too low it will ruin your fast forward max speeds. I did say I didn't want to resort to placebo tricks, but I also don't want to spark up public discussion on this again either. So it might be best to default Input/Latency to 0ms, and internally have a max(5, latency) wrapper around the value. |

Update to v099r16 release (public beta).
byuu says: Changelog: - hiro: BrowserDialog can navigate up to drive selection on Windows - nall: (file,path,dir,base,prefix,suffix)name => Location::(file,path,dir,base,prefix,suffix) - higan/tomoko: rename audio filter label from "Sinc" to "IIR - Biquad" - higan/tomoko: allow loading files via icarus on the command-line once again - higan/tomoko: (begrudging) quick hack to fix presentation window focus on startup - higan/audio: don't divide output audio volume by number of streams - processor/r65816: fix a regression in (read,write)DB; fixes Taz-Mania - fixed compilation regressions on Windows and Linux 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. |

Update to v099r14 release.
byuu says:
Changelog:
- (u)int(max,ptr) abbreviations removed; use _t suffix now [didn't feel
like they were contributing enough to be worth it]
- cleaned up nall::integer,natural,real functionality
- toInteger, toNatural, toReal for parsing strings to numbers
- fromInteger, fromNatural, fromReal for creating strings from numbers
- (string,Markup::Node,SQL-based-classes)::(integer,natural,real)
left unchanged
- template<typename T> numeral(T value, long padding, char padchar)
-> string for print() formatting
- deduces integer,natural,real based on T ... cast the value if you
want to override
- there still exists binary,octal,hex,pointer for explicit print()
formatting
- lstring -> string_vector [but using lstring = string_vector; is
declared]
- would be nice to remove the using lstring eventually ... but that'd
probably require 10,000 lines of changes >_>
- format -> string_format [no using here; format was too ambiguous]
- using integer = Integer<sizeof(int)*8>; and using natural =
Natural<sizeof(uint)*8>; declared
- for consistency with boolean. These three are meant for creating
zero-initialized values implicitly (various uses)
- R65816::io() -> idle() and SPC700::io() -> idle() [more clear; frees
up struct IO {} io; naming]
- SFC CPU, PPU, SMP use struct IO {} io; over struct (Status,Registers) {}
(status,registers); now
- still some CPU::Status status values ... they didn't really fit into
IO functionality ... will have to think about this more
- SFC CPU, PPU, SMP now use step() exclusively instead of addClocks()
calling into step()
- SFC CPU joypad1_bits, joypad2_bits were unused; killed them
- SFC PPU CGRAM moved into PPU::Screen; since nothing else uses it
- SFC PPU OAM moved into PPU::Object; since nothing else uses it
- the raw uint8[544] array is gone. OAM::read() constructs values from
the OAM::Object[512] table now
- this avoids having to determine how we want to sub-divide the two
OAM memory sections
- this also eliminates the OAM::synchronize() functionality
- probably more I'm forgetting
The FPS fluctuations are driving me insane. This WIP went from 128fps to
137fps. Settled on 133.5fps for the final build. But nothing I changed
should have affected performance at all. This level of fluctuation makes
it damn near impossible to know whether I'm speeding things up or slowing
things down with changes.

Update to v099r08 release.
byuu says:
Changelog:
- nall/vfs work 100% completed; even SGB games load now
- emulation cores now call load() for the base cartridges as well
- updated port/device handling; portmask is gone; device ID bug should
be resolved now
- SNES controller port 1 multitap option was removed
- added support for 128KiB SNES PPU VRAM (for now, edit sfc/ppu/ppu.hpp
VRAM::size=0x10000; to enable)
Overall, nall/vfs was a huge success!! We've substantially reduced
the amount of boilerplate code everywhere, while still allowing (even
easier than before) support for RAM-based game loading/saving. All of
nall/stream is dead and buried.
I am considering removing Emulator::Interface::Medium::id and/or
bootable flag. Or at least, doing something different with it. The
values for the non-bootable GB/BS/ST entries duplicate the ID that is
supposed to be unique. They are for GB/GBC and WS/WSC. Maybe I'll use
this as the hardware revision selection ID, and then gut non-bootable
options. There's really no reason for that to be there. I think at one
point I was using it to generate library tabs for non-bootable systems,
but we don't do that anymore anyway.
Emulator::Interface::load() may not need the required flag anymore ... it
doesn't really do anything right now anyway.
I have a few reasons for having the cores load the base cartridge. Most
importantly, it is going to enable a special mode for the WonderSwan /
WonderSwan Color in the future. If we ever get the IPLROMs dumped ... it's
possible to boot these systems with no games inserted to set user profile
information and such. There are also other systems that may accept being
booted without a cartridge. To reach this state, you would load a game and
then cancel the load dialog. Right now, this results in games not loading.
The second reason is this prevents nasty crashes when loading fails. So
if you're missing a required manifest, the emulator won't die a violent
death anymore. It's able to back out at any point.
The third reason is consistency: loading the base cartridge works the
same as the slot cartridges.
The fourth reason is Emulator::Interface::open(uint pathID)
values. Before, the GB, SB, GBC modes were IDs 1,2,3 respectively. This
complicated things because you had to pass the correct ID. But now
instead, Emulator::Interface::load() returns maybe<uint> that is nothing
when no game is selected, and a pathID for a valid game. And now open()
can take this ID to access this game's folder contents.
The downside, which is temporary, is that command-line loading is
currently broken. But I do intend on restoring it. In fact, I want to do
better than before and allow multi-cart booting from the command-line by
specifying the base cartridge and then slot cartridges. The idea should
be pretty simple: keep a queue of pending filenames that we fill from
the command-line and/or drag-and-drop operations on the main window,
and then empty out the queue or prompt for load dialogs from the UI
when booting a system. This also might be a bit more unorthodox compared
to the traditional emulator design of "loadGame(filename)", but ... oh
well. It's easy enough still.
The port/device changes are fun. We simplified things quite a bit. The
portmask stuff is gone entirely. While ports and devices keep IDs,
this is really just sugar-coating so UIs can use for(auto& port :
emulator->ports) and access port.id; rather than having to use for(auto
n : range(emulator->ports)) { auto& port = emulator->ports[n]; ... };
but they should otherwise generally be identical to the order they appear
in their respective ranges. Still, don't rely on that.
Input::id is gone. There was no point since we also got rid of the nasty
Input::order vector. Since I was in here, I went ahead and caved on the
pedantics and renamed Input::guid to Input::userData.
I removed the SNES controller port 1 multitap option. Basically, the only
game that uses this is N-warp Daisakusen and, no offense to d4s, it's
not really a good game anyway. It's just a quick demo to show 8-players
on the SNES. But in the UI, all it does is confuse people into wasting
time mapping a controller they're never going to use, and they're going
to wonder which port to use. If more compelling use cases for 8-players
comes about, we can reconsider this. I left all the code to support this
in place, so all you have to do is uncomment one line to enable it again.
We now have dsnes emulation! :D
If you change PPU::VRAM::size to 0x10000 (words), then you should now
have 128KiB of VRAM. Even better, it serializes the used-VRAM size,
so your save states shouldn't crash on you if you swap between the two
(though if you try this, you're nuts.)
Note that this option does break commercial software. Yoshi's Island in
particular. This game is setting A15 on some PPU register writes, but
not on others. The end result of this is things break horribly in-game.
Also, this option is causing a very tiny speed hit for obvious reasons
with the variable masking value (I'm even using size-1 for now.) Given
how niche this is, I may just leave it a compile-time constant to avoid
the overhead cost. Otherwise, if we keep the option, then it'll go into
Super Famicom.sys/manifest.bml ... I'll flesh that out in the near-future.
----
Finally, some fun for my OCD ... my monitor suddenly cut out on me
in the middle of working on this WIP, about six hours in of non-stop
work. Had to hit a bunch of ctrl+alt+fN commands (among other things)
and trying to log in headless on another TTY to do issue commands,
trying to recover the display. Finally power cycled the monitor and it
came back up. So all my typing ended up going to who knows where.
Usually this sort of thing terrifies me enough that I scrap a WIP and
start over to ensure I didn't screw anything up during the crashed screen
when hitting keys randomly.
Obviously, everything compiles and appears to work fine. And I know
it's extremely paranoid, but OCD isn't logical, so ... I'm going
to go over every line of the 100KiB r07->r08 diff looking for any
corruption/errors/whatever.
----
Review finished.
r08 diff review notes:
- fc/controller/gamepad/gamepad.cpp:
use uint device = ID::Device::Gamepad; not id = ...;
- gb/cartridge/cartridge.hpp:
remove redundant uint _pathID; (in Information::pathID already)

add " - Slot (A,B)" to interface->load("Sufami Turbo"); to be more
descriptive
- sfc/controller/gamepad/gamepad.cpp:
use uint device = ID::Device::Gamepad; not id = ...;
- sfc/interface/interface.cpp:
remove n variable from the Multitap device input generation loop
(now unused)
- sfc/interface/interface.hpp:

- ui-tomoko:
cheats.bml is reading from/writing to mediumPaths(0) [system folder
instead of game folder]
- ui-tomoko:
instead of mediumPaths(1) - call emulator->metadataPathID() or something
like that

Update to v096r01 release.
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.
