Update to v101r04 release.
byuu says:
Changelog:
- pulled the (u)intN type aliases into higan instead of leaving them
in nall
- added 68K LINEA, LINEF hooks for illegal instructions
- filled the rest of the 68K lambda table with generic instance of
ILLEGAL
- completed the 68K disassembler effective addressing modes
- still unsure whether I should use An to decode absolute
addresses or not
- pro: way easier to read where accesses are taking place
- con: requires An to be valid; so as a disassembler it does a
poor job
- making it optional: too much work; ick
- added I/O decoding for the VDP command-port registers
- added skeleton timing to all five processor cores
- output at 1280x480 (needed for mixed 256/320 widths; and to handle
interlace modes)
The VDP, PSG, Z80, YM2612 are all stepping one clock at a time and
syncing; which is the pathological worst case for libco. But they also
have no logic inside of them. With all the above, I'm averaging around
250fps with just the 68K core actually functional, and the VDP doing a
dumb "draw white pixels" loop. Still way too early to tell how this
emulator is going to perform.
Also, the 320x240 mode of the Genesis means that we don't need an aspect
correction ratio. But we do need to ensure the output window is a
multiple 320x240 so that the scale values work correctly. I was
hard-coding aspect correction to stretch the window an additional \*8/7.
But that won't work anymore so ... the main higan window is now 640x480,
960x720, or 1280x960. Toggling aspect correction only changes the video
width inside the window.
It's a bit jarring ... the window is a lot wider, more black space now
for most modes. But for now, it is what it is.

Update to v099r07 release.
byuu says:
Changelog:
- (hopefully) fixed BS Memory and Sufami Turbo slot loading
- ported GB, GBA, WS cores to use nall/vfs
- completely removed loadRequest, saveRequest functionality from
Emulator::Interface and ui-tomoko
- loadRequest(folder) is now load(folder)
- save states now use a shared Emulator::SerializerVersion string
- whenever this is bumped, all older states will break; but this makes
bumping state versions way easier
- also, the version string makes it a lot easier to identify
compatibility windows for save states
- SNES PPU now uses uint16 vram[32768] for memory accesses [hex_usr]
NOTE: Super Game Boy loading is currently broken, and I'm not entirely
sure how to fix it :/
The file loading handoff was -really- complicated, and so I'm kind of
at a loss ... so for now, don't try it.
Everything else should theoretically work, so please report any bugs
you find.
So, this is pretty much it. I'd be very curious to hear feedback from
people who objected to the old nall/stream design, whether they are
happy with the new file loading system or think it could use further
improvements.
The 16-bit VRAM turned out to be a wash on performance (roughly the same
as before. 1fps slower on Zelda 3, 1fps faster on Yoshi's Island.) The
main reason for this was because Yoshi's Island was breaking horribly
until I changed the vramRead, vramWrite functions to take uint15 instead
of uint16.
I suspect the issue is we're using uint16s in some areas now that need
to be uint15, and this game is setting the VRAM address to 0x8000+,
causing us to go out of bounds on memory accesses.
But ... I want to go ahead and do something cute for fun, and just because
we can ... and this new interface is so incredibly perfect for it!! I
want to support an SNES unit with 128KiB of VRAM. Not out of the box,
but as a fun little tweakable thing. The SNES was clearly designed to
support that, they just didn't use big enough VRAM chips, and left one
of the lines disconnected. So ... let's connect it anyway!
In the end, if we design it right, the only code difference should be
one area where we mask by 15-bits instead of by 16-bits.

Update to v098r04 release.
byuu says:
Changelog:
- SFC: fixed behavior of 21fx $21fe register when no device is connected
(must return zero)
- SFC: reduced 21fx buffer size to 1024 bytes in both directions to
mirror the FT232H we are using
- SFC: eliminated dsp/modulo-array.hpp [1]
- higan: implemented higan/video interface and migrated all cores to it
[2]
[1] the echo history buffer was 8-bytes, so there was no need for it at
all here. Not sure what I was thinking. The BRR buffer was 12-bytes, and
has very weird behavior ... but there's only a single location in the
code where it actually writes to this buffer. It's much easier to just
write to the buffer three times there instead of implementing an entire
class just to abstract away two lines of code. This change actually
boosted the speed from ~124.5fps to around ~127.5fps, but that's within
the margin of error for GCC. I doubt it's actually faster this way.
The DSP core could really use a ton of work. It comes from a port of
blargg's spc_dsp to my coding style, but he was extremely fond of using
32-bit signed integers everywhere. There's a lot of opportunity to
remove red tape masking by resizing the variables to their actual state
sizes.
I really need to find where I put spc_dsp6.sfc from blargg. It's a great
test to verify if I've made any mistakes in my implementation that would
cause regressions. Don't suppose anyone has it?
[2] so again, the idea is that higan/audio and higan/video are going to
sit between the emulation cores and the user interfaces. The hope is to
output raw encoding data from the emulation cores without having to
worry about the video display format (generally 24-bit RGB) of the host
display. And also to avoid having to repeat myself with eg three
separate implementations of interframe blending, and so on.
Furthermore, the idea is that the user interface can configure its side
of the settings, and the emulation cores can configure their sides.
Thus, neither has to worry about the other end. And now we can spin off
new user interfaces much easier without having to mess with all of these
things.
Right now, I've implemented color emulation, interframe blending and
SNES horizontal color bleed. I did not implement scanlines (and
interlace effects for them) yet, but I probably will at some point.
Further, for right now, the WonderSwan/Color screen rotation is busted
and will only show games in the horizontal orientation. Obviously this
must be fixed before the next official release, but I'll want to think
about how to implement it.
Also, the SNES light gun pointers are missing for now.
Things are a bit messy right now as I've gone through several revisions
of how to handle these things, so a good house cleaning is in order once
everything is feature-complete again. I need to sit down and think
through how and where I want to handle things like light gun cursors,
LCD icons, and maybe even rasterized text messages.
And obviously ... higan/audio is still just nall::DSP's headers. I need
to revamp that whole interface. I want to make it quite powerful with
a true audio mixer so I can handle things like
SNES+SGB+MSU1+Voicer-Kun+SNES-CD (five separate audio streams at once.)
The video system has the concept of "effects" for things like color
bleed and interframe blending. I want to extend on this with useful
other effects, such as NTSC simulation, maybe bringing back my mini-HQ2x
filter, etc. I'd also like to restore the saturation/gamma/luma
adjustment sliders ... I always liked allowing people to compensate for
their displays without having to change settings system-wide. Lastly,
I've always wanted to see some audio effects. Although I doubt we'll
ever get my dream of CoreAudio-style profiles, I'd like to get some
basic equalizer settings and echo/reverb effects in there.

Update to v098r12 release.
byuu says:
Changelog:
- higan/video: added support for Emulator::Sprite
- higan/resource: a new system for accessing embedded binary files
inside the emulation cores; holds the sprites
- higan/sfc/superscope,justifier: re-enabled display of crosshairs
- higan/sfc/superscope: fixed turbo toggle (also shows different
crosshair color when in turbo mode)
- higan/sfc/ppu: always outputs at 512x480 resolution now
- causes a slight speed-hit from ~127fps to ~125fps;
- but allows high-resolution 32x32 cursors that look way better;
- also avoids the need to implement sprite scaling logic
Right now, the PPU code to always output at 480-height is a really gross
hack. Don't worry, I'll make that nicer before release.
Also, superscope.cpp and justifier.cpp are built around a 256x240
screen. But since we now have 512x480, we can make the cursor's movement
much smoother by doubling the resolution on both axes. The actual games
won't see any accuracy improvements when firing the light guns, but the
cursors will animate nicer so I think it's still worth it. I'll work on
that before the next release as well.
The current 32x32 cursors are nicer, but we can do better now with full
24-bit color. So feel free to submit alternatives. I'll probably reject
them, but you can always try :D
The sprites don't support alpha blending, just color keying (0x00000000
= transparent; anything else is 0xff......). We can revisit that later
if necessary.
The way I have it designed, the only files that do anything with
Emulator::Sprite at all are the superscope and justifier folders.
I didn't have to add any hooks anywhere else. Rendering the sprite is
a lot cleaner than the old code, too.

Update to v088r10 release.
byuu says:
ethos is going to be absolutely amazing. You guys are in for a treat :D
I'm impressing the hell out of myself with how well-structured this code
is, it's allowing me to do amazing new things.
Just a small sampling of what's in store (and already implemented):
The file browser will display folders as "[ folder name ]", and
cartridge folders as "Game Name" (no extension, no /) [icons would be
nicer, but well ... phoenix.]
Folders are sorted above cartridge folders.
Cartridge folders for other systems do not show up in the list.
Not only are unique paths stored for each image type, your position in
the list is saved across runs.
Some voodoo was added to GTK+ so that all targets even scroll directly
to that item when you open the list. Load->System->Enter restarts your
last game.
That sounds really simple and obvious, but it makes an -incredible-
difference. Didn't realize it until I tried an implementation of it,
wow.
The input mapping list now lets you bind as many hotkeys as you want to
any given input.
So SFC::Port1::Joypad::B = Keyboard::Z or Joypad::Button1 ... no need to
remap everything to switch between keyboard and joypad. Either one
activates the key.
There is a separate Hotkeys tab now. This should hopefully end the
confusion about how to remap hotkeys that users experience.
Hotkeys are different, too. Instead of OR logic, they use AND logic.
So Fullscreen = Keyboard::Alt and Keyboard::Enter. Both must be pressed
to enter the key. This lets you easily implement "super" modifier keys.
The actual codebase has new features the old UI never had, and has about
~50% of the old functionality (so far, of course), yet is only ~25% as
much code.
The entire GUI no longer needs to pull in all the headers for each
emulated system. It just needs a small interface header file.
Then bind the entire system with exactly **two** lines of code.
Everything is dynamically generated for you after that.

Update to v100 release.
byuu says:
higan has finally reached v100!
I feel it's important to stress right away that this is not "version
1.00", nor is it a major milestone release. Rather than arbitrary version
numbers, all of my software simply bumps version numbers by one for each
official release. As such, higan v100 is simply higan's 100th release.
That said, the primary focus of this release has been code
clean-ups. These are always somewhat dangerous in that regressions are
possible. We've tested through sixteen WIP revisions, one of which was
open to the public, to try and minimize any regressions. But all the same,
please report any regressions if you discover any.
Changelog (since v099):
FC: render during pixels 1-256 instead of 0-255 [hex_usr]
FC: rewrote controller emulation code
SFC: 8% speedup over the previous release thanks to PPU optimizations
SFC: fixed nasty DB address wrapping regression from v099
SFC: USART developer controller removed; superseded by 21fx
SFC: Super Multitap option removed from controller port 1; ports
renamed 2-5
SFC: hidden option to experiment with 128KB VRAM (strictly for novelty)
higan: audio volume no longer divided by number of audio streams
higan: updated controller polling code to fix possible future mapping
issues
higan: replaced nall/stream with nall/vfs for file-loading subsystem
tomoko: can now load multi-slotted games via command-line
tomoko: synchronize video removed from UI; still available in the
settings file
tomoko, icarus: can navigate to root drive selection on Windows
all: major code cleanups and refactoring (~1MB diff against v099)
Note 1: the audio volume change means that SGB and MSU1 games won't
lose half the volume on the SNES sounds anymore. However, if one goes
overboard and drives the sound all the way to max volume with the MSU1,
clamping may occur. The obvious solution is not to drive volume that high
(it will vastly overpower the SNES audio, which usually never exceeds
25% volume.) Another option is to lower the volume in the audio settings
panel to 50%. In general, neither is likely to ever be necessary.
Note 2: the synchronize video option was hidden from the UI because it
is no longer useful. With the advent of compositors, the loss of the
complicated timing settings panel, support for the WonderSwan and its
75hz display, the need to emulate variable refresh rate behaviors in the
Game Boy, the unfortunate latency spike and audio distortion caused by
long Vsync pauses, and the arrival of adaptive sync technology ... it
no longer makes sense to present this option. However, as stated, you
can edit settings.bml to enable this option anyway if you insist and
understand the aforementioned risks.
Changelog (since v099r16 open beta):
- fixed MSU1 audio sign extension
- fixed compilation with SGB support disabled
- icarus can now navigate to root directory
- fixed compilation issues with OS X port
- (hopefully) fixed label height issue with hiro that affected icarus
import dialog
- (mostly) fixed BS Memory, Sufami Turbo slot loading
Errata:
- forgot to remove the " - Slot A", " - Slot B" suffixes for Sufami
Turbo slot loading
- this means you have to navigate up one folder and then into Sufami
Turbo/ to load games for this system
- moving WonderSwan orientation controls to the device slot is causing
some nastiness
- can now select orientation from the main menu, but it doesn't rotate
the display

Update to v102r28 release.
byuu says:
Changelog:
- higan: `Emulator::<Platform::load>()` now returns a struct containing
both a path ID and a string option
- higan: `Emulator::<Platform::load>()` now takes an optional final
argument of string options
- fc: added PAL emulation (finally, only took six years)
- md: added PAL emulation
- md: fixed address parameter to `VDP::Sprite::write()`; fixes missing
sprites in Super Street Fighter II
- md: emulated HIRQ counter; fixes many games
- Super Street Fighter II - status bar

- ms: added PAL emulation
- sfc: added the ability to override the default region auto-detection
- sfc: removed "system.region" override setting from `Super Famicom.sys`
- tomoko: added options list to game folder load dialog window
- tomoko: added the ability to specify game folder load options on the
command-line
So, basically ... Sega forced a change with the way region detection
works. You end up with games that can run on multiple regions, and the
content changes accordingly. Bare Knuckle in NTSC-J mode will become
Streets of Rage in NTSC-U mode. Some games can even run in both NTSC and
PAL mode.
In my view, there should be a separate ROM for each region a game was
released in, even if the ROM content were identical. But unfortunately
that's not how things were done by anyone else.
So to support this, the higan load dialog now has a drop-down at the
bottom-right, where you can choose the region to load games from. On the
SNES, it defaults to "Auto", which will pull the region setting from the
manifest, or fall back on NTSC. On the Mega Drive ... unfortunately, I
can't auto-detect the region from the ROM header. $1f0 is supposed to
contain a string like "JUE", but instead you get games like Maui Mallard
that put an "A" there, and other such nonsense. Sega was far more lax
than Nintendo with the ROM header validity. So for now at least, you
have to manually select your region every time you play a Mega Drive
game, thus you have "NTSC-J", "NTSC-U", and "PAL". The same goes for the
Master System for the same reason, but there's only "NTSC" and "PAL"
here. I'm not sure if games have a way to detect domestic vs
international consoles.
And for now ... the Famicom is the same as well, with no auto-detection.
I'd sincerely hope iNES has a header bit for the region, but I didn't
bother with updating icarus to support that yet.
The way to pass these parameters on the command-line is to prefix the
game path with "option:", so for example:
higan "PAL:/path/to/Sonic the Hedgehog (USA, Europe).md"
If you don't provide a prefix, it uses the default (NTSC-J, NTSC, or
Auto.) Obviously, it's not possible to pass parameters with
drag-and-drop, so you will always get the default option in said case.

The 16-bit VRAM turned out to be a wash on performance (roughly the same

until I changed the vramRead, vramWrite functions to take uint15 instead
of uint16.
I suspect the issue is we're using uint16s in some areas now that need
to be uint15, and this game is setting the VRAM address to 0x8000+,
causing us to go out of bounds on memory accesses.
But ... I want to go ahead and do something cute for fun, and just because

Changelog:
- processor/arm: corrected MUL instruction timings [Jonas Quinn]
- processor/wdc65816: finished phase two of the rewrite
I'm really pleased with the visual results of the wdc65816 core rewrite.
I was able to eliminate all of the weird `{Boolean,Natural}BitRange`
templates, as well as the need to use unions/structs. Registers are now
just simple `uint24` or `uint16` types (technically they're `Natural<T>`
types, but then all of higan uses those), flags are now just bool types.
I also eliminated all of the implicit object state inside of the core
(aa, rd, dp, sp) and instead do all computations on the stack frame with
local variables. Through using macros to reference the registers and
individual parts of them, I was able to reduce the visual tensity of all
of the instructions. And by using normal types without implicit states,
I was able to eliminate about 15% of the instructions necessary, instead
reusing existing ones.
The final third phase of the rewrite will be to recode the disassembler.
That code is probably the oldest code in all of higan right now, still
using sprintf to generate the output. So it is very long overdue for a
cleanup.
And now for the bad news ... as with any large code cleanup, regression
errors have seeped in. Currently, no games are running at all. I've left
the old disassembler in for this reason: we can compare trace logs of
v102r23 against trace logs of v102r25. The second there's any
difference, we've spotted a buggy instruction and can correct it.
With any luck, this will be the last time I ever rewrite the wdc65816
core. My style has changed wildly over the ~10 years since I wrote this
core, but it's really solidifed in recent years.

ethos is going to be absolutely amazing. You guys are in for a treat :D
I'm impressing the hell out of myself with how well-structured this code
is, it's allowing me to do amazing new things.
Just a small sampling of what's in store (and already implemented):
The file browser will display folders as "[ folder name ]", and
cartridge folders as "Game Name" (no extension, no /) [icons would be
nicer, but well ... phoenix.]
Folders are sorted above cartridge folders.
Cartridge folders for other systems do not show up in the list.
Not only are unique paths stored for each image type, your position in
the list is saved across runs.
Some voodoo was added to GTK+ so that all targets even scroll directly
to that item when you open the list. Load->System->Enter restarts your
last game.
That sounds really simple and obvious, but it makes an -incredible-
difference. Didn't realize it until I tried an implementation of it,
wow.
The input mapping list now lets you bind as many hotkeys as you want to
any given input.
So SFC::Port1::Joypad::B = Keyboard::Z or Joypad::Button1 ... no need to
remap everything to switch between keyboard and joypad. Either one
activates the key.
There is a separate Hotkeys tab now. This should hopefully end the
confusion about how to remap hotkeys that users experience.
Hotkeys are different, too. Instead of OR logic, they use AND logic.
So Fullscreen = Keyboard::Alt and Keyboard::Enter. Both must be pressed
to enter the key. This lets you easily implement "super" modifier keys.
The actual codebase has new features the old UI never had, and has about
~50% of the old functionality (so far, of course), yet is only ~25% as
much code.
The entire GUI no longer needs to pull in all the headers for each
emulated system. It just needs a small interface header file.
Then bind the entire system with exactly **two** lines of code.
Everything is dynamically generated for you after that.

Update to v088r08 release.

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.
