- save savedata before loading state
- fix silly initstate ifreg regression
- save state selection
- save state osd preview snapshots
- fix a few potential security holes when loading invalid state
- get rid of some undefined behaviour in statesaver

depth users

- add bitmap font rendering with font based on Bitstream Vera Sans
- osd state n saved/loaded text
- empty state osd thumbs marked with "Empty" text

cases to disabled area assuming ceiled power of 2 address bus.
- no sprites or sprite mapping busy cycles on first line after display
enable. slight cleanup.
- small oam accessibility correction.
- Tile loading and tile rendering can seemingly get out of sync when
modifying scx at a critical time. Another pessimation with little gain in
the name of accuracy.
- Use a look-up table to do tile byte merging.
- Append "_dmg" to save base name when forcing DMG mode, to avoid
corrupting CGB save files and vice versa.
- saner ly write behaviour
- Add adapted and optimized hq3x.
- Revert to big f'ing switch hq2x code, as there's less duplication now.

- macx fixed/variable window size change issue fixed
- macx opengl drawbuffer change issues worked around
- add openal engine, default on macx
- add macx quartz video mode toggler
- multi-head infrastructure

- more work-arounds for Qt failing to set correct geometry on video mode

close to right after sync wait is over as possible

unsupported.
- temporarily return to original video mode and minimize on full screen
alt-tab (except on macx or if there are multiple screens), switch back on
focus-in
- hide mouse cursor after move timeout, or key/joystick pressed (more sane
on macx)
- exit fullscreen rather than toggle menubar on macx (note that the menubar
will automatically pop-up on macx full screen if the mouse is moved to
the top of the primary screen)
- add (independent) pause counter for non-client pauses.
- reset X11 screen saver on joystick activity
- change "turbo"-mode to temporarily set frametime as a way of avoiding
vsync issues (for a laugh, check out the video dialog while in
fast-forward mode and see "Sync to vertical blank in 65535 and 131070 Hz
modes").

the geometry gets properly reset after fullscreen
- Add directdraw device selection.

- Add tab support to input settings dialog.
- Add alternate key support to input settings dialog.
- Auto-focus to next likely input box after settings key in input dialog.
- Add "Play" and "State" input settings dialog tabs.
- Avoid using the most convenient keys as forced menu short-cuts, set them
as default keys in input settings dialog instead. This unfortunately
makes the more useful shortcuts less visible, but it allows remapping
the most convenient keyboard keys.
- Avoid duplicate joystick axis "press" events by keeping a map of axis
states.
- Make sure to discard irrelevant/old joystick events.
- Don't give MediaSource button events when stopped.
- Allow joystick-based button events while paused by using a very
low-frequency poll timer.
- Make some of the joystick event wrapping stuff less messy.
- missing string include
- use QString for videoSourceLabel passed to MainWindow constructor
- store currently selected scheme as string, since it appears ModelIndex
is neither tied to the data it points to nor invalidated by changes.
enforce valid state on reject since the list of schemes may have
changed.
- Direct3DCreate function pointer typedef needs WINAPI macro
- disable page flipping dependent checkboxes in constructor to ensure
correct start state
- add custom sample rate support
- change default buffer latency to 67 ms
- don't auto-repeat buttons bound to keyboard
- use enums for somewhat more robust gambattesource button setup
- fix silly "alsa not using default device by default" bug
- Only ask for xrandr config once to avoid potential server roundtrips in
some xrandr versions.
- Make sure xrandr version is >= 1.1 and < 2
- Prevent all text editing of input boxes.
- Add custom context menu to input boxes.
- Update AudioEngine to support sample rate estimation in terms of OS
timers.
- Implement sample rate estimation in ALSA and OSS audio engines.
- AlsaEngine: Revert to using snd_pcm_avail_update for buffer status since
snd_pcm_delay may consider external latencies.
- AlsaEngine: Use snd_pcm_hw_params_set_buffer_time_near. Don't request a
particular number of periods per buffer.
- AlsaEngine: Use hw as default custom device string, rather than hw:0,0.
- OssEngine: Don't trust GETOSPACE fragment info.
- Estimate optimal frame rate based on sample rate estimations.
- Extend BlitterWidget to support estimation of vsynced frame rate in terms
of OS timers.
- Implement vsync frame rate estimation in QGlBlitter, Direct3DBlitter and
DirectDrawBlitter.
- Use a combination of OS timer sample rate estimation and vsync frame rate
estimation to derive resampling ratio for no-frame-duplication vsync.
- Change API to reflect MediaSources not being responsible for resampling.
- Make sure to parent PaletteDialog list model, so it gets deleted properly.
- Various refactoring, small changes and stuff I forgot.
- limit vsync frame rate estimation deviation
- More averaging in estimation code.
- Stricter estimate deviation limit
- Adjust estimated frame time each frame.
- Use half frame time if audio buffer is close to underrun.
- Provide combined audioengine write and status get, to avoid doing
potentially expensive operations twice. Utilized in OSS and ALSA engines.
- Saner vsync estimate variance protection.
- allow dynamically setting samples per frame
- Don't bother allowing sources the choice of which output sample rates are
selecrable, as it's not really a per source thing at this point. If
resampling avoidance is desired, then that should rather be a user option
(to depend on the OS for resampling, which is mostly nonsensical for the
Game Boy/NES/PSG-system case btw).
- Move Qt media framework to a separate subdir
- postpone buffered x11 blits to after sync.
- Add support for XRandR 1.2 + multi-head
- use crtc mode dimensions rather than crtc dimensions when discarding
modes since crtc dimensions may be rotated
- Fractional bits for intermediate rate estimation averages.
- Add RateEst reset method. Initialize RateEst count to 1.
- Less refresh rate estimation averaging.
- Allow more refresh rate estimation deviation.
- Return NULL paintEngine in windows blitters that use the PaintToScreen
attribute.
- Add checks for things not being initialized in DirectDraw-blitter and
QPainterBlitter paintEvents.
- Don't reparent blitters (mainly to make a bug in Qt 4.4.3 win less
annoying, widgets that do internal reparenting are still affected).
- Check for window position less than screen top-left after mode change,
before full screen, to avoid Qt moving it to the primary screen.
- Add rate estimation to DirectSound engine.
- Better underrun detection in DirectSound engine.
- Don't duplicate blitter pointer in mainwindow.
- Use RateEst.reset rather than re-initing on pause.
- Add CoreAudio engine with rate estimation and buffer status support.
Default engine on Mac OS X.
- 44100 Hz default sample rate on OS X, since OS X tends to resample
everything to 44100 Hz.
- Get rid of buffer status averaging in OpenAlEngine, since it makes
assumptions on usage pattern that shouldn't be made.
- Fix CoreAudio engine reporting buffer status in samples rather than
frames.
- Update SDL_Joystick to SDL-1.2 SVN.
- #undef UNICODE in win32/SDL_mmjoystick.c to avoid joystick name mangling.
- work around annoying random non-updating OpenGL on Mac OS X after full
screen.
common/other:
- Fix GCC 4.3 warnings about people getting confused by operator precedence
by adding parentheses.
- Real-time, sophisticated resampling framework with several
performance/quality profiles for dynamically generated windowed sinc and
CIC chains based on analysis of fourier transforms and optimal cost
equations. Fast 2-tap linear as a low quality alternative.
- Move non-emulation common code to a common directory to avoid duplication.
- Update front-ends to new libgambatte API.
- Utilize resampling framework in front-ends. Selectable resamplers.
- Improved adaptive sleep class that estimates oversleep.
- Various refactoring, small changes and stuff I forgot.
- Do per phase normalization to avoid dc fluctuations.
- More averaging in estimation code.
- Stricter estimate deviation limit
- Fractional bits for intermediate rate estimation averages.
- Add RateEst reset method. Initialize RateEst count to 1.
- Extend ringbuffer.h to support resetting size, and move it to common dir
since gambatte_qt/coreaudioengine uses it too now.
- Add "force DMG mode" option.
- Allow more rate estimation deviation.
hwtests:
- wx affects sprite m3 cycles.
- cgb dma from various areas results in 0xFF being written.
- add hwtests for oam dma
- m3 cycles wo bg
- more oamdma tests
- various oamdma accuracy. oamdma bus conflicts with cpu, ppu, cgbdma.
- accurate timing of ppu sprite mapping reads.
