Changelog:

  - higan: Emulator::Interface::videoSize() renamed to videoResolution()
  - higan: Emulator::Interface::rtcsync() renamed to rtcSynchronize()
  - higan: added video display rotation support to Video
  - GBA: substantially improved audio mixing
      - fixed bug with FIFO 50%/100% volume setting
      - now properly using SOUNDBIAS amplitude to control output
        frequencies
      - reduced quantization noise
      - corrected relative volumes between PSG and FIFO channels
      - both PSG and FIFO values cached based on amplitude; resulting in
        cleaner PCM samples
      - treating PSG volume=3 as 200% volume instead of 0% volume now
        (unverified: to match mGBA)
  - GBA: properly initialize ALL CPU state; including the vital
    prefetch.wait=1 (fixes Classic NES series games)
  - GBA: added video rotation with automatic key translation support
  - PCE: reduced output resolution scalar from 285x242 to 285x240
      - the extra two scanlines won't be visible on most TVs; and they
        make all other cores look worse
      - this is because all other cores output at 240p or less; so they
        were all receiving black bars in windowed mode
  - tomoko: added "Rotate Display" hotkey setting
  - tomoko: changed hotkey multi-key logic to OR instead of AND
      - left support for flipping it back inside the core; for those so
        inclined; by uncommenting one line in input.hpp
  - tomoko: when choosing Settings→Configuration, it will
    automatically select the currently loaded system
      - for instance, if you're playing a Game Gear game, it'll take you
        to the Game Gear input settings
      - if no games are loaded, it will take you to the hotkeys panel
        instead
  - WS(C): merged "Hardware-Vertical", "Hardware-Horizontal" controls
    into combined "Hardware"
  - WS(C): converted rotation support from being inside the core to
    using Emulator::Video
      - this lets WS(C) video content scale larger now that it's not
        bounded by a 224x224 square box
  - WS(C): added automatic key rotation support
  - WS(C): removed emulator "Rotate" key (use the general hotkey
    instead; I recommend F8 for this)
  - nall: added serializer support for nall::Boolean (boolean) types
      - although I will probably prefer the usage of uint1 in most cases

Tim Allen a4629e1f64 Update to v102r21 release.

Changelog:

  - GBA: fixed WININ2 reads, BG3PB writes [Jonas Quinn]
  - R65816: added support for yielding/resuming from WAI/STP¹
  - SFC: removed status.dmaCounter functionality (also fixes possible
    TAS desync issue)
  - tomoko: added support for combinatorial inputs [hex\_usr\]²
  - nall: fixed missing return value from Arithmetic::operator--
    [Hendricks266]

Now would be the time to start looking for major regressions with the
new GBA PPU renderer, I suppose ...

¹: this doesn't matter for the master thread (SNES CPU), but is
important for slave threads (SNES SA1). If you try to save a state and
the SA1 is inside of a WAI instruction, it will get stuck there forever.
This was causing attempts to create a save state in Super Bomberman
- Panic Bomber W to deadlock the emulator and crash it. This is now
finally fixed.

Note that I still need to implement similar functionality into the Mega
Drive 68K and Z80 cores. They still have the possibility of deadlocking.
The SNES implementation was more a dry-run test for this new
functionality. This possible crashing bug in the Mega Drive core is the
major blocking bug for a new official release.

²: many, many thanks to hex\_usr for coming up with a really nice
design. I mostly implemented it the exact same way, but with a few tiny
differences that don't really matter (display " and ", " or " instead of
" & ", " | " in the input settings windows; append → bind;
assignmentName changed to displayName.)

The actual functionality is identical to the old higan v094 and earlier
builds. Emulated digital inputs let you combine multiple possible keys
to trigger the buttons. This is OR logic, so you can map to eg
keyboard.up OR gamepad.up for instance. Emulated analog inputs always
sum together. Emulated rumble outputs will cause all mapped devices to
rumble, which is probably not at all useful but whatever. Hotkeys use
AND logic, so you have to press every key mapped to trigger them. Useful
for eg Ctrl+F to trigger fullscreen.

Obviously, there are cases where OR logic would be nice for hotkeys,
too. Eg if you want both F11 and your gamepad's guide button to trigger
the fullscreen toggle. Unfortunately, this isn't supported, and likely
won't ever be in tomoko. Something I might consider is a throw switch in
the configuration file to swap between AND or OR logic for hotkeys, but
I'm not going to allow construction of mappings like "(Keyboard.Ctrl and
Keyboard.F) or Gamepad.Guide", as that's just too complicated to code,
and too complicated to make a nice GUI to set up the mappings for.

Tim Allen e39987a3e3 Update to v101 release.
byuu says (in the public announcement):

Not a large changelog this time, sorry. This release is mostly to fix
the SA-1 issue, and to get some real-world testing of the new scheduler
model. Most of the work in the past month has gone into writing a 68000
CPU core; yet it's still only about half-way finished.

Changelog (since the previous release):

  - fixed SNES SA-1 IRQ regression (fixes Super Mario RPG level-up
    screen)
  - new scheduler for all emulator cores (precision of 2^-127)
  - icarus database adds nine new SNES games
  - added Input/Frequency to settings file (allows simulation of
    latency)

byuu says (in the WIP forum):

Changelog:

  - in 32-bit mode, Thread uses uint64\_t with 2^-63 time units (10^-7
    precision in the worst case)
      - nearly ten times the precision of an attosecond
  - in 64-bit mode, Thread uses uint128\_t with 2^-127 time units
    (10^-26 precision in the worst case)
      - far more accurate than yoctoseconds; almost closing in on planck
        time

Note: a quartz crystal is accurate to 10^-4 or 10^-5. A cesium fountain
atomic clock is accurate to 10^-15. So ... yeah. 2^-63 was perfectly
fine; but there was no speed penalty whatsoever for using uint128\_t in
64-bit mode, so why not?

Tim Allen f5e5bf1772 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.

Tim Allen a816998122 Update to v099r10 release.
byuu says:

Changelog:
- higan/profile/ => higan/systems/ [temporary; unless we can't think of
  a better base folder name]
- god-damn-better-have fixed the input polling bug
- re-added command-line and drag-and-drop loading
  - command-line loading can now load multiple folders at once (SGB+GB
    game; Sufami Turbo+Slot A+Slot B; etc)
  - if you load just the base cart, it'll present you with a dialog to
    optionally load slotted cart(s)
- MSU1 now goes through nall/vfs instead of directly accessing the
  filesystem
- Famicom Cartridge, PPU cores updated to newer programming style
  - there's countless opportunity for BitField and .bits() in the PPU
    ... but I'm worried about breaking things

If anyone has a working MSU1 game and can test the changes out, that'd
be appreciated. I still don't have a test ROM on my dev box.

I wouldn't worry too much about extensively testing the Famicom PPU
changes just yet ... I'm still struggling with what to name the structs
inside the classes between all of my emulators, and the BitField/.bits()
changes will be much more important to test at a later date.

The only use case left for Emulator::Interface::path(uint id) is for
21fx emulation. This peripheral loads a DLL/SO via LoadLibrary/dlopen,
which do not have any official ways to open a file in RAM. I'm
very hesitant to use the portable trick of writing the memory to a
temporary file, loading it, and deleting the temporary file once done
... it's a real waste of disk activity. I might make something like
vfs::file::isVirtual->bool,path()->string to get around this. But even
once I do, the underlying LoadLibrary/dlopen call is still going to be
direct disk access.

Tim Allen 0d0af39b44 Update to v097r14 release.
byuu says:

This is a few days old, but oh well.

This WIP changes nall,hiro,ruby,icarus back to (u)int(8,16,32,64)_t.

I'm slowly pushing for (u)int(8,16,32,64) to use my custom
Integer<Size>/Natural<Size> classes instead. But it's going to be one
hell of a struggle to get that into higan.

Tim Allen 344e63d928 Update to v097r02 release.
byuu says:

Note: balanced/performance profiles still broken, sorry.

Changelog:
- added nall/GNUmakefile unique() function; used on linking phase of
  higan
- added nall/unique_pointer
- target-tomoko and {System}::Video updated to use
  unique_pointer<ClassName> instead of ClassName* [1]
- locate() updated to search multiple paths [2]
- GB: pass gekkio's if_ie_registers and boot_hwio-G test ROMs
- FC, GB, GBA: merge video/ into the PPU cores
- ruby: fixed ~AudioXAudio2() typo

[1] I expected this to cause new crashes on exit due to changing the
order of destruction of objects (and deleting things that weren't
deleted before), but ... so far, so good. I guess we'll see what crops
up, especially on OS X (which is already crashing for unknown reasons on
exit.)

[2] right now, the search paths are: programpath(), {configpath(),
"higan/"}, {localpath(), "higan/"}; but we can add as many more as we
want, and we can also add platform-specific versions.

Tim Allen 47d4bd4d81 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.

It's a boring WIP, I just wanted to push out the project structure
change now at the start of this WIP cycle.
