0.8.B:
Fixed the rectangle calculation for screen rotation with Lynx and
WonderSwan to use X scale and Y scale values appropriately (they
were reversed before; also, assuming square pixels on your monitor
;)). Rotation still poses a problem in fullscreen with the default
settings, however.
Fixed an off-by-one error in the software SDL graphics rotation
code (used for Lynx and WonderSwan).
Fixed a race condition that could cause rapid oscillation between
fullscreen and windowed when trying to toggle it.
...and fixed a race condition that could cause oscillations when
rotating the screen with Lynx and WonderSwan emulation.
SexyAL: The return values of ALSA functions are now treated as
errors only if they're less than 0, rather than non-zero as before.
Thanks to R.L. for pointing this out.
The default "nethost" setting is now "fobby.net" instead of
"mednafen.com". The latter was allowed to expire and lost to domain
squatters some time ago. Domain squatters cause desires to commit
grievous face-stabbing. However, the netplay server on "fobby.net"
is not guaranteed to be up. :p
PCE: Added the ability to load a custom colormap(palette) by
setting "pce.colormap" to the path of the colormap file. The
colormap consists of either 512 or 1024 RGB triplets, 8-bits per
color component, in the order R,G,B,R,G,B,R,G,B,... . It is
recommended that the colormap provide all 1024 entries(the first
512 entries are for normal mode, the second 512 entries are for
grayscale/strip-colorburst mode). If it doesn't, Mednafen will
calculate the grayscale colors using a formula similar to that used
with the real VCE, but with more precision. The colormap may be
disabled by setting the "pce.colormap" setting to an empty string,
or 0. Command-line examples:
mednafen -pce.colormap /path/to/blueblue.cmap /yarr/pirate/booty.pce [Enable]
mednafen -pce.colormap 0 /some/where/over/the/rainbow/islands.cue [Disable]
PCE: Added a hack to fix games that try to write to VRAM while
VRAM DMA is in progress (fixes graphical glitches in "Crest of Wolf",
maybe others too?). This could potentially cause regressions, so
please post any on the forum.
PCE: Having "pce.forcesgx" set to 1 with non-SuperGrafx games will
no longer cause problems with display timing(and positioning).
However, this doesn't fix the underlying issue, and any demos that
set the horizontal and vertical timing registers differently on
each VDC won't operate as they would on a real SuperGrafx. (This
could affect commercial SuperGrafx games, but AFAIK they keep the
VDC timings the same). NOTE: Setting "pce.forcesgx" to 1 is still
not recommended, the preferred way of forcing a game/demo to enable
SuperGrafx emulation is by giving it a file extension of "sgx".
PCE: Arcade Card RAM is now initialized to 0 on allocation(it was
erroneously being left uninitialized before).
PCE: Added Arcade Card RAM to the memory editor in the debugger.
PCE: Fixed the BRAM initialization (it was wrong, and generated from
when Mednafen erroneously emulated 8KiB of BRAM). Fixes lockups
in "Sorcerian". Note that if you have any existing save states or
battery-backed RAM files for "Sorcerian" in "sav" or "mcs" under
Mednafen's base directory from when you attempted to run "Sorcerian",
you will need to delete them for this fix to have any effect.
PCE: Reduced the mirroring address space range of the Arcade Card
register mapping in HuC6280 banks 0x40-0x43. It was mirrored
throughout 0x40-0x4F, now it's only mirrored at 0x40-0x47. It may
not be mirrored at all with a real Arcade Card, tests need to be
performed!
Fixes a crashing bug in "Linda Cubed" early into gameplay.
WonderSwan: Fixed a bug that made it impossible to push a direction
on one D-pad while the opposing direction was being pressed on the
other D-pad.

-- 0.4.1 -- 2009-01-10
libgambatte:
- Fix HqXx filter pitch.
- Fix mbc2 not getting a rambank.
- Make sure to reset passed pointers when deleted. Fixes potential crash
when loading ROM during OAM busy.
common:
- Substantially improved rate estimation averaging.
- RateEst: Add a convenient way of filtering measures that extend beyond
a buffer time, and are as such probably invalid.
- RateEst: Allow using a custom timestamp in feed().
- RateEst: Keep a queue of the last ~100 msec worth of samples and
duration, and filter out collective samples that give a pre-estimate
that seems way off.
- Replace "Game Boy / Game Boy Color emulator" with "Game Boy Color
emulator" for now to avoid misleading anyone on the current status.
gambatte_qt:
- Disable BlitterWidget updates (paintEvents) while not paused.
- QGLBlitter: Do a cheap front blit rather than a vsynced flip if audio
buffers are low.
- Allow BlitterWidgets to opt in to get paintEvents while unpaused. Do so
for QGLBlitter since it may need to clear buffers afterwards.
- QGLBlitter: Try to blit right after sync in the case of single buffering.
- Up default audio buffer latency to 100 ms (some common system audio
servers require a lot of buffering to work well).
- Adaptively skip BlitterWidget syncs if audio buffer is low, in a manner
that should minimize wasted skips in sync to vblank situation, and tries
to be non-disturbing. This replaces frame time halving, and blitter
specific rescueing.
- Clear display buffers in DirectDrawBlitter and Direct3DBlitter in
exclusive mode, since blits don't necessarily cover the entire buffers.
- DirectDrawBlitter: Make sure that a minimum amount of time has passed
between calls to WaitForVerticalBlank, since it can return in the same
vblank period twice on a fast system.
- DirectDrawBlitter: Support vsync for refresh rate ~= 2x frame rate.
- DirectDrawBlitter: Refactor somewhat and get rid of a couple minor
potential bugs.
- DirectDrawBlitter: Some tweaks to get updates closer to sync time in
certain situations.
- DirectDrawBlitter: Some tweaks to better support DONOTWAIT.
- DirectDrawBlitter: Make only updating during vblank while page flipping
optional.
- Direct3DBlitter: Some tweaks to get updates closer to sync time in
certain situations.
- Filter out very short frame times in frame time estimation.
- Don't adjust frame time during turbo, but rather skip BlitterWidget
syncs to speed up, which avoids vsync limits without disabling vsync.
- DirectDrawBlitter: Add triple buffering option.
- Direct3DBlitter: Use D3DSWAPEFFECT_DISCARD in non-exclusive mode.
- Direct3DBlitter: Allow triple buffering and vblank-only updates in
non-excusive mode.
- Rename "Page flipping" in Direct3D and DirectDraw blitters to
"Exclusive full screen".
- Pause audio on win32 titlebar clicks/drags to avoid looping audio due to
underruns from blocked timerEvents.
- Use wildcards for platform detection to avoid being unnecessarily
compiler/architecture specific. Fixes bug 2377772.
- Rewrite most of DirectSoundEngine, supporting primary buffer option,
making it more robust, correct and hopefully cleaner. Only use part of
the primary buffer if the desired buffer size is lower than the
primary buffer size.
- Direct3DBlitter and DirectDrawBlitter: Force blocking updates when sync
to vblank is enabled. Some updates only block if there's a prior
unfinished update in progress. This screws up frame time estimation in
turn screwing up vsync. To fix this we do a double update (and extra blit)
if close to a frame time period has passed since the last update when
sync to vblank is enabled. I really should have noticed this earlier as
it pretty much breaks vsync adaption completely.
- Direct3DBlitter: Use the D3DCREATE_FPU_PRESERVE flag when creating
device. Omitting this flag can screw up floating point calculations in
other parts of the code. For instance WASAPI cursor timestamps get
utterly screwed up here.
- Direct3DBlitter: It appears that managed textures are updated before
they are unlocked, which screws up redraws, making things appear choppy
in some situations. Use a default memory texture and a system memory
texture and the UpdateTexure method instead.
- DirectSoundEngine: Make use of the sample period limit feature of
RateEst, rather than duplicating the feature.
- Add polling WASAPI engine with exclusive mode support. Latency and rate
estimation is generally better than DirectSound, and in exclusive mode
there is less blocking as well as exclusive mode being better than
shared mode in the other areas too.
- WasapiEngine: Add device selection.
- WasapiEngine: Add static isUsable() method. Only listed if isUsable().
Default engine if isUsable().
- WasapiEngine: Use default device if there's only one device available,
since we don't show the combobox anyway.
- DirectSoundEngine: Provide the integrated read and status get write
method optimization.
- XvBlitter: Set NosystemBackground attribute rather than OpaquePaintEvent.
Reimplement paintEngine to return NULL as suggested by Qt docs.
- X11Blitter: Reimplement paintEngine to return NULL.
- AlsaEngine: Make use of sample period limit feature of RateEst. Don't
increase estimated sample rate on underrun.
- OssEngine: Make use of sample period limit feature of RateEst. Don't
increase estimated sample rate on underrun.
- Esc exits fullscreen on macx.
- Drop OpenAL from default macx binary.
- Add some useful but commented build flags for macx to .pro files.
0.8.A:
NES: Cleaned up the iNES loading code a bit, and added
support for WRAM on a few mappers that nominally shouldn't
have WRAM, enabled if the battery-backed bit is set in the
iNES header. Fixes "Family BASIC", and probably
a few bootleg games as well.
NES: Added partially-broken support for mapper 163.
NES: Added support for mapper 241.
Fixed string constant-to-(char *) problems in drivers/cheat.cpp
Added setting "osd.state_display_time", to control the
length of time, in milliseconds, the save state/movie
screen is displayed after selecting a save state or movie.
The most recently-saved save state slot will now be colored
differently when selecting a save state slot.
Increased the brightness of non-empty save state slots.
Empty save state slots are now black instead of being
partially transparent.
PC-FX: Fixed bugs in "Play Audio Track Index" and "Read
Subchannel" MMC commands, fixing the totally broken
cinematic sequences in "Boundary Gate". There may still
be bugs in these commands that don't cause any known
problems with games, so I will need to run tests on a real
system.
GBA: An error loading the custom colormap file is now
treated as fatal.
Win32: The German and Russian translation files are now
included in the Win32 precompiled binary distribution
ZIP file. Note that Mednafen always assumes the locale to
be UTF-8, so the stdio.txt file will need to be
opened with a viewer that can handle UTF-8(though filenames
with non-7-bit-ASCII components will appear fubar).
(I am aware that assuming the locale's character encoding
to always be UTF-8 is a design flaw with
various insidious consequences when the encoding is not
UTF-8).
Updated the Russian translation with the translation done
by rubicon.
Added configure script option "--enable-altivec/--disable-altivec
(default: enabled)" for compiling on
PowerPC architectures where AltiVec is not supported, or
causes problems. This configure script option is
untested, however.
Input for the virtual device on virtual port N will be
disabled when the buttons on the virtual device on virtual
port N are being configured. The last button pressed when
in button configuration may still be taken as
virtual device input, however(a fix for this would be too
invasive, and so will be done in the 0.9.x unstable
tree).
PCE: Added several missing input-related state variables
to save states, fixing several netplay/movie
desynchronization issues under certain situations.
Fixed a bug when creating an SDL source surface, whose
negative effects(clipping rightmost columns) could be
triggered when the "sdl" vdriver setting was used with
certain xscale and yscale settings that would
cause a 1:1 pixel copy operation.
PC-FX: Improved PSG LFO emulation again(Tyoushin Heiki
Zeroigar uses it for some sound effects, other
games likely use it as well in similar roles).
PCE: Improved PSG LFO emulation again(Hanii in the Sky,
Juuouki, and Flash Hiders use LFO).
PCE: Altered the Street Fighter 2 autodetection code to be
data-agnostic. The SF2 mapper will now be enabled for
any ROM images 2MiB and over in size.
Fixed a call to putenv(), to pass a static character array
initialized to a string constant instead of a string
constant directly.
Fixed a few argument descriptions(invoked with the -help
command-line switch) that weren't properly gettextized.
Debugger: Fixed a bug in the trace log code. It would
cause the emulator to lock up if the user pressed
Enter/Return in the prompt popup without any text in the input field.
SMS: Removed the old unused Z80 emulator code from when
SMS Plus was assimilated.
* Some simple 64-bit apps should now run.
* Support for subpixel font rendering.
* 64-bit code generation in the IDL compiler.
* New version of the Gecko engine.
* Various bug fixes.
