Changes:

* The 256TC key code has been improved allowing faster key entry and eliminating lost key presses.

* When using 'roms.md5.auto' and the 'roms.alias' files the ROMs directory will automatically be re-scanned for MD5s when a ROM file can not be located before retrying again.

* Changes to the option module to allow run time only options.

* Changed all prefixed (+abcd) type arguments to use '+' and '-' prefixes. The new '-' prefix has the opposite affect to '+' where this is supported. The arguments are now also checked for errors.

* Changed 'clear' and 'none' arguments to 'all' for --regs, --keystd-mod, --osd, --status and --output options. These use the new +/- prefixes.

* --pak(n) options can now also specify 4K ROMs for A and B.

* The 2mhz model can now load 4K EPROM images by default.

* Changes to vdu_init() function to clear the colour RAM with 0s to prevent the checker board pattern on start-up. This is only a temporary work around and the real solution may need some type of 6545 initialisation delay to make it work like a real model.

* Changes to make the console much more responsive when emulator is paused.

* Configuration files may now use trailing '\' line append characters.

* Improvements made to detect errors in option argument conversions.

* Improvements made to --help option to provide better information.

* Changes made to the 'ubee512rc.sample', 'games.ini.sample' and 'roms.alias.sample' configuration files.

Fixed:

* The Teleterm model is now working after some changes and bug fixes to the TC key and PIO interrupt code.

* 256TC code that used TC key interrupts should work much better.

* Fixed a regression bug introduced in v4.0.0 that had originally been fixed earlier in v2.8.0 concerning calling the rtc_poll() function. The 256TC boot ROMs now updates the time again.

* Fixed --varuset option as was incorrectly removing a variable entry resulting in segmentation error when creating a new variable.

* Fixed -if-* compare options as an incorrect result was being returned in some circumstances.

* Fixed a problem loading a Basic ROM image on the '2mhz' model when a 16K image was not available and 4K images were available instead.

* The --modio reporting on a port access should now show the correct Z80 PC address where the i/o instruction occurred instead of after completion.

* Fixed bug in ubee512 API that was causing or had the potential for HOSTDIR and HOST2CPM tools to crash.

So what's new? This is a rather small update.

 

- The license for data now matches the source code license, making MEKA a fully free (as in freedom) software.

- New mappers were added to support a wider range of Korean games.

- Debugger got a few fixes and new RMAP command ("reverse map") which allow to retrieve back, eg, a ROM address given an address in CPU space. The SYM @addr command allows to find a symbol given an address.

- Fixed SC-3000 keyboard, improved capture options, helpers for creating game maps, fixed Light Phaser cursor, etc.

- And generally other tweaks, fixes and lots of updates to the MEKA database.

This will be the final release in the 0.8.x branch, unless 0.8.D introduces any major bug(s) that do not have workaround(s).

 

Changes since the last stable release, 0.8.C:

 

0.8.D:

SMS: Some state that wasn't being saved in save states now is, which should fix netplay desynch problems with SMS/GG games.

 

Fixed a couple of remotely-exploitable(if connected to a malicious server) stack manipulation bugs in the network play code.

 

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.

 

0.8.D-rc1:

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 netplay.

 

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 :.

- And a huge amount of improvements and bug fixes which we don't remember anymore

 

 

 

This time the distribution will be a bit different. There are 3 versions, the full installer, the web installer and the binary. We highly recommend people to use our torrents to lower the load of our server and for faster distribution. You will need a torrent client such as utorrent to download them.
