Changelog:
- major restructuring of board manifests
- cleanup of generic board names
- Super Famicom: updates to SA1, SuperFX, Cx4, SPC7110, EpsonRTC,
SharpRTC load/save code
- Super Famicom: added experimental SuperFX plot dithering fix
[qwertymodo]
- higan, icarus: rename shared folders to lowercase names; put .sys
folders into new subfolder
- Video Shaders/ → shaders/
- Database/ → database/
- Firmware/ → firmware/
- \*.sys/ → systems/\*.sys/
So right now, only standard SNES games, SA-1, SuperFX, and Cx4 games
load. I have not tested SPC7110 or RTC support, because icarus import
seems to be completely broken? It's creating blank folders when I try it
now. I'll have to fix that ...
Since we are now up to thirteen systems, I've put the .sys folders into
a subfolder. This should declutter the main higan-windows release folder
a good deal. Linux users will need to re-run make install, or manually
move things into a new systems/ subfolder.
Same goes for icarus: lowercase the database/ and firmware/ folders or
re-run make install.
I don't know if qwertymodo's SuperFX fix is exactly correct or not.
Hopefully it is, but I didn't write a test ROM or anything to be
certain. Since SuperFX games should run, if people could please play
through some of them and look for any regressions, that'd be very much
appreciated.

- if firmware isn't appended, it still cuts out the size from the
memory/program.rom file
- boards.bml is still missing the new Japanese production boards

Changelog:
- Super Famicom: added support for loading manifests without embedded
mapping information¹
- genius: initial commit
- various Makefile cleanups
¹: so the idea here is to try and aim for a stable manifest format,
and to allow direct transposition of icarus/genius database entries into
manifest files. The exact mechanics of how this is going to work is
currently in flux, but we'll get there.
For right now, `Super Famicom.sys` gains `boards.bml`, which is the raw
database from my board-editor tool, and higan itself tries to load
`boards.bml`, match an entry to game/board from the game's `manifest.bml`
file, and then transform it into the format currently used by higan. It
does this only when the game's `manifest.bml` file lacks a board node.
When such a board node exists, it works as previous versions of higan
did.
The only incompatible change right now is information/title is now
located at game/label. I may transition window title display to just use
the filenames instead.
Longer term, some thought is going to need to go into the format of the
`boards.bml` database itself, and at which point in the process I should
be transforming things.
Give it time, we'll refine this into something nicer.

Changelog:
- nall/GNUmakefile: build=release changed to -O2, build=optimize is
now -O3
- hiro: added Monitor::dpi(uint index) → Position [returns logical
DPI for x, y]
- Position is a bad name, but dpi(monitor).(x,y)() make more sense
than .(width,height)()
- hiro: Position, Size, Geometry, Font changed from using signed int
to float
- hiro: Alignment changed from using double to float
- hiro: added skeleton (unused) Application::scale(), setScale()
functions
Errata:
- hiro/cocoa's Monitor::dpi() is untested. Probably will cause issues
with macOS' automatic scaling.
- hiro/gtk lacks a way to get both per-monitor and per-axis (x,y) DPI
scaling
- hiro/qt lacks a way to get per-monitor DPI scaling (Qt 5.x has this,
but I still use Qt 4.x)
- and just to get global DPI, hiro/qt's DPI retrieval has to use
undocumented functions ... fun
The goal with this WIP was basically to prepare hiro for potential
automatic scaling. It'll be extremely difficult, but I'm convinced that
it must be possible if macOS can do it.
By moving from signed integers to floats for coordinates, we can now
scale and unscale without losing precision. That of course isn't the
hard part, though. The hard part is where and how to do the scaling. In
the ideal application, hiro/core and hiro/extension will handle 100% of
this, and the per-platform hiro/(cocoa,gtk,qt,windows) will not be aware
of what's going on, but ... to even make that possible, things will need
to change in every per-platform core, eg the per-platform code will have
to call a core function to change geometry, which will know about the
scaling and unscale the values back down again.
Gonna be a lot of work, but ... it's a start.

et al⁴
¹: because there's no concept of a controller for cartridge inputs,
I'm attaching to the base platform for now. An idea I had was to make
separate ports for each cartridge type ... but this would duplicate the
rumble input between MBC5 and MBC7. And would also be less discoverable.
But it would be more clean in that users wouldn't think the Game Boy
hardware had this functionality. I'll think about it.
²: it probably won't work yet. Rumble isn't documented anywhere, but
I dug through an emulator named GEST and discovered that it seems to use
bit 3 of the RAM bank select to be rumble. I don't know if it sets the
bit for rumbling, then clears when finished, or if it sets it and then
after a few milliseconds it stops rumbling. I couldn't test on my
FreeBSD box because SDL 1.2 doesn't support rumble, udev doesn't exist
on FreeBSD, and nobody has ever posted any working code for how to use
evdev (or whatever it's called) on FreeBSD.
³: I'm still thinking about specifying the MBC7 RAM as EEPROM, since
it's not really static RAM.
⁴: if possible, please test all drivers if you can. I want to ensure
they're all working. Especially let me know if the following work:
macOS: input.carbon Linux: audio.pulseaudiosimple, audio.ao (libao)
If I can confirm these are working, I'm going to then remove them from
being included with stock higan builds.
I'm also considering dropping SDL video on Linux/BSD. XShm is much
faster and supports blurring. I may also drop SDL input on Linux, since
udev works better. That will free a dependency on SDL 1.2 for building
higan. FreeBSD is still going to need it for joypad support, however.

inverted; counter decrements)
- md/apu: power/reset do not cancel 68K bus requests
- md/apu: 68K is not granted bus access on Z80 power/reset
- md/controller: replaced System::Peripherals with ControllerPort
concept
- md/controller: CTRL port is now read-write, maintains value across
controller changes (and soon, soft resets)
- md/psg: PSG sampling rate unintentionally modified¹
- processor/spc700: improve cycle timing of (indirect),y instructions
[Overload]
- processor/spc700: idle() cycles actually read from the program
counter; much like the 6502 [Overload]
- some of the idle() cycles should read from other addresses; this
still needs to be supported
- processor/spc700: various cleanups to instruction function naming
- processor/z80: prefix state (HL→IX,IY override) can now be
serialized
- icarus: fix install rule for certain platforms (it wasn't buggy on
FreeBSD, but was on Linux?)
¹: the clock speed of the PSG is oscillator/15. But I was setting the
sampling rate to oscillator/15/16, which was around 223KHz. I am not
sure whether the PSG should be outputting at 3MHz or 223KHz. Amazingly
... I don't really hear a difference either way `o_O` I didn't actually
mean to make this change; I just noticed it after comparing the diff
between r01 and r02. If this turns out to be wrong, set
stream = Emulator::audio.createStream(1, frequency() / 16.0);
in md/psg.cpp to revert this change.

Changelog:
- added higan/emulator/platform.hpp (moved out Emulator::Platform from
emulator/interface.hpp)
- moved gmake build paramter to nall/GNUmakefile; both higan and
icarus use it now
- added build=profile mode
- MD: added the region select I/O register
- MD: started to add region selection support internally (still no
external select or PAL support)
- PCE: added cycle stealing when reading/writing to the VDC or VCE;
and when using ST# instructions
- PCE: cleaned up PSG to match the behavior of Mednafen (doesn't
improve sound at all ;_;)
- note: need to remove loadWaveSample, loadWavePeriod
- HuC6280: ADC/SBC decimal mode consumes an extra cycle; does not set
V flag
- HuC6280: block transfer instructions were taking one cycle too many
- icarus: added code to strip out PC Engine ROM headers
- hiro: added options support to BrowserDialog
The last one sure ended in failure. The plan was to put a region
dropdown directly onto hiro::BrowserDialog, and I had all the code for
it working. But I forgot one important detail: the system loads
cartridges AFTER powering on, so even though I could technically change
the system region post-boot, I'd rather not do so.
So that means we have to know what region we want before we even select
a game. Shit.

So ... the major news this time is the removal of the soft reset
behavior. This is a major!! change that results in a 100KiB diff file,
and it's very prone to accidental mistakes!! If anyone is up for
testing, or even better -- looking over the code changes between v102r01
and v102r02 and looking for any issues, please do so. Ideally we'll want
to test every NES mapper type and every SNES coprocessor type by loading
said games and power cycling to make sure the games are all cleanly
resetting. It's too big of a change for me to cover there not being any
issues on my own, but this is truly critical code, so yeah ... please
help if you can.
We technically lose a bit of hardware documentation here. The soft reset
events do all kinds of interesting things in all kinds of different
chips -- or at least they do on the SNES. This is obviously not ideal.
But in the process of removing these portions of code, I found a few
mistakes I had made previously. It simplifies resetting the system state
a lot when not trying to have all the power() functions call the reset()
functions to share partial functionality.
In the future, the goal will be to come up with a way to add back in the
soft reset behavior via keyboard binding as with the Master System core.
What's going to have to happen is that the key binding will have to send
a "reset pulse" to every emulated chip, and those chips are going to
have to act independently to power() instead of reusing functionality.
We'll get there eventually, but there's many things of vastly greater
importance to work on right now, so it'll be a while. The information
isn't lost ... we'll just have to pull it out of v102 when we are ready.
Note that I left the SNES reset vector simulation code in, even though
it's not possible to trigger, for the time being.
Also ... the Super Game Boy core is still disconnected. To be honest, it
totally slipped my mind when I released v102 that it wasn't connected
again yet. This one's going to be pretty tricky to be honest. I'm
thinking about making a third GameBoy::Interface class just for SGB, and
coming up with some way of bypassing platform-> calls when in this
mode.
byuu says:
I refactored my schedulers. Added about ten lines to each scheduler, and
removed about 100 lines of calling into internal state in the scheduler
for the FC,SFC cores and about 30-40 lines for the other cores. All of
its state is now private.
Also reworked all of the entry points to static auto Enter() and auto
main(). Where Enter() handles all the synchronization stuff, and main()
doesn't need the while(true); loop forcing another layer of indentation
everywhere.
Took a few hours to do, but totally worth it. I'm surprised I didn't do
this sooner.
Also updated icarus gmake install rule to copy over the database.

This WIP finally achieves the vision I've had for icarus.
I also fixed a mapping issue with Cx4 that, oddly enough, only caused
the "2" from the Mega Man X2 title screen to disappear.
[Editor's note - "the vision for icarus" was described in a separate,
public forum post: http://board.byuu.org/phpbb3/viewtopic.php?p=20584
Quoting for posterity:
icarus is now a full-fledged part of higan, and will be bundled with
each higan WIP as well. This will ensure that in the future, the
exact version of icarus you need to run higan will be included right
along with it. As of this WIP, physical manifest files are now truly
and entirely optional.
From now on, you can associate your ROM image files with higan's
main binary, or drop them directly on top of it, to load and play
your games.
Furthermore, there are two new menu options that appear under the
library menu when icarus is present:
- "Load ROM File ..." => gives you a single-file selection dialog to
import (and if possible) run the game
- "Import ROM Files ..." => gives you a multi-file import dialog
with checkboxes to pull in multiple games at once
Finally, as before, icarus can generate manifest.bml files for
folders that lack them.
For people who like the game folder and library system, nothing's
changed. Keep using higan as you have been.
For people who hate it, you can now use higan like your classic
emulators. Treat the "Library->{System Name}" entries as your
"favorites" list: the games you actually play. Treat the
"Library->Load ROM" as your standard open file dialog in other
emulators. And finally, treat "Advanced->Game Library" as your save
data path for cheat codes, save states, save RAM, etc.

Warning: this is not for the faint of heart. This is a very early,
unpolished, buggy release. But help testing/fixing bugs would be greatly
appreciated for anyone willing.
Requirements:
- Mac OS X 10.7+
- Xcode 7.2+
Installation Commands:
cd higan
gmake -j 4
gmake install
cd ../icarus
gmake -j 4
gmake install
(gmake install is absolutely required, sorry. You'll be missing key
files in key places if you don't run it, and nothing will work.)
(gmake uninstall also exists, or you can just delete the .app bundles
from your Applications folder, and the Dev folder on your desktop.)
If you want to use the GBA emulation, then you need to drop the GBA BIOS
into ~/Emulation/System/Game\ Boy\ Advance.sys\bios.rom
Usage:
You'll now find higan.app and icarus.app in your Applications folders.
First, run icarus.app, navigate to where you keep your game ROMs. Now
click the settings button at the bottom right, and check "Create
Manifests", and click OK. (You'll need to do this every time you run
icarus because there's some sort of bug on OSX saving the settings.) Now
click "Import", and let it bring in your games into ~/Emulation.
Note: "Create Manifests" is required. I don't yet have a pipe
implementation on OS X for higan to invoke icarus yet. If you don't
check this box, it won't create manifest.bml files, and your games won't
run at all.
Now you can run higan.app. The first thing you'll want to do is go to
higan->Preferences... and assign inputs for your gamepads. At the very
least, do it for the default controller for all the systems you want to
emulate.
Now this is very important ... close the application at this point so
that it writes your config file to disk. There's a serious crashing bug,
and if you trigger it, you'll lose your input bindings.
Now the really annoying part ... go to Library->{System} and pick the
game you want to play. Right now, there's a ~50% chance the application
will bomb. It seems the hiro::pListView object is getting destroyed, yet
somehow the internal Cocoa callbacks are being triggered anyway. I don't
know how this is possible, and my attempts to debug with lldb have been
a failure :(
If you're unlucky, the application will crash. Restart and try again. If
it crashes every single time, then you can try launching your game from
the command-line instead. Example:
open /Applications/higan.app \
--args ~/Emulation/Super\ Famicom/Zelda3.sfc/
Help wanted:
I could really, really, really use some help with that crashing on game
loading. There's a lot of rough edges, but they're all cosmetic. This
one thing is pretty much the only major show-stopping issue at the
moment, preventing a wider general audience pre-compiled binary preview.
byuu says:
After 20 months of development, higan v095 is released at long last!
The most notable feature is vastly improved Game Boy Advance emulation.
With many thanks to endrift, Cydrak, Jonas Quinn and jchadwick, this
release contains substantially improved CPU timings and many bugfixes.
Being one of only two GBA emulators to offer ROM prefetch emulation,
higan is very near mGBA in terms of accuracy, and far ahead of all
others. As a result of these fixes, compatibility is also much higher
than in v094.
There are also several improvements to SNES emulation. Most
significantly is support for mid-scanline changes to the background mode
in the accuracy profile.
Due to substantial changes to the user interface library used by higan,
this release features yet again a brand-new UI. With the exception of
video shaders and NSS DIP switch selection, it is at feature-parity with
the previous UI. It also offers some new features that v094 lacked.
The cheat code database has also been updated to the latest version by
mightymo.
