pkgsrc/emulators/mednafen: Makefile distinfo
Update to 0.8.D.2 (0.8.13.2 in pkgsrc terms):
NES: Fixed a crash on certain x86_64 platforms(Mac OS X),
due to the sound filtering code dereferencing 32-bit
registers instead of 64-bit registers as it should have.
Fixed a compilation error on gcc 4.5(thanks to hanno for
pointing it out).
SMS: Some state that wasn't being saved in save states
now is, which should fix netplay desynch problems with
Fixed a couple of remotely-exploitable(if connected to a
malicious server) stack manipulation bugs in the network
Fixed an incorrect object creation bug in pce/adpcm.cpp.
NES: Added a missing CPU emulator variable to save states.
PCE: Added a missing CPU emulator variable to save states.
Lynx: Fixed a bug in the cart loader code that would cause
a crash if the ROM bank size was larger than the actual
data available in the file(as is the case with some homebrew
programs). Thanks to "Wookie" for the patch.
Build files were regenerated using autoconf 2.64 and aclocal
1.11(previously, they were generated with autoconf 2.61
and aclocal 1.10.1).
Fixed a crashing problem when entering an invalid menu
choice("0") in the cheat interface. Thanks to tsenart for
reporting the bug.
GB: The GameBoy module now respects the "filesys.disablesavegz"
setting in respect to saved battery-backed RAM.
Added support for "lurkers" on the network play server.
Previous versions of Mednafen don't lack support for this
per se, but there would be cosmetic issues with status
messages printed to the internal console.
SexyAL: Fixed a bug affecting the return value from
RawCanWrite() in the ALSA driver. The returned value was
typically too small by a factor of 4. The effects of this
bug included potential long periods of garbled sound during
Fixed the return value from RawCanWrite() in the JACK
driver. It was being clamped to a value that was too small
by a factor of 4; however, the clamp value was already
excessively large in a way that this bug would should have
only been triggered if the "soundbufsize" setting was
excessively large. The effects of this bug would be similar
to the ALSA RawCanWrite() bug.
The ALSA and OSS drivers will now try to set audio output
to 2 channels if the source data only has 1 channel, and
16-bit signed if the source data is 8-bit(automatic conversion
is done). This is done to allow for lower period/fragment
sizes, as, in ALSA's internals at least, the minimum period
sizes are expressed in bytes, not sound frames.
The ALSA and OSS drivers will now try to set lower
period/fragment sizes than previous versions of Mednafen
did. With default settings, for ALSA, the new period/fragment
size is 50% of what it was before, and for OSS, 25%. Also,
there's a new setting to override the SexyAL's driver's
preferred period/fragment sizes, named "sound.period_time"(default
value of 0: no override). The period/fragment size is
expressed in microseconds. If the new, lower fragment
sizes cause problems, the setting can be changed to "2666"
to approximate the fragment size selection in previous
versions of Mednafen when using ALSA output, and "5333"
when using OSS output.
Added a workaround to the OSS driver for a bug in ALSA(and
hence, ALSA's in-kernel OSS emulation) that could cause
the emulator to run far too fast for a short period of time
if a buffer underflow occurred.
The ALSA's driver's RawCanWrite() method now(finally) uses
snd_pcm_avail_update() instead of snd_pcm_delay(). This
should improve performance and frameskipping behavior when
the ALSA output is not routed directly to a physical device,
such as the case with PulseAudio(though PulseAudio is still
not recommended :b). CVS:
