September 27, 2005 - Mednafen 0.3.4 Released

This release is primarily focused on improving PC Engine emulation.

Changes since 0.3.2(0.3.3 was a private release):

 

* Added command-line option "-autofirefreq" for setting the frequency of the configured auto-fire buttons when playing NES and PC Engine games.

* PCE:  Fixed Street Fighter 2 HuCard emulation.

* PCE:  Modified PSG waveform writing/DDA emulation, fixes "Fire Pro Wrestling - Combination Tag".

* PCE:  Modified TRB and TSB emulation.  Fixes "Toy Shop Boys".

* PCE:  Implemented VRAM-VRAM DMA direction control bits.

* PCE:  Altered VDC timing, fixing a few games, making a few games more bouncy.

* PCE:  Fixed sprite clipping on the left side of the screen.

* PCE:  The emulated RCR register is now masked with 0x3FF when being set.  Fixes Niko Niko Pun.

* PCE:  Several CPU cycles are now emulated between setting the in-vblank flag and the vblank IRQ occurring.  This works around an issue that would otherwise require timing granularity as small as one cpu cycle.  Interestingly, this same type of problem occurs with NES emulation.

* PCE:  Altered the display rectangle calculation code to take into effect screen areas that may be hidden on many television sets (and some games were designed with the assumption that these areas WOULD be hidden).

* PCE:  Modified noise emulation...again. :b

* PCE:  Modified LFO emulation, fixes major sound problems in "Bull Fight".

* PCE:  The sprite DMA completion IRQ now occurs earlier(probably a few cycles too early now, but oh well).  Fixes some graphical issues in "Bull Fight".

* PCE:  Sprite bit plane selection is now emulated to a degree.  Fixes "Fighting Run".

* PCE:  Very high-frequency(and probably inaudible) sounds are no longer played, because Blip_Synth can't handle them well.  Fixes "Bouken Danshaku Don" and others.

What's New:

 

What is LDU technology? It is Gens32's mother. And now, she has came back. She can read the text and pictures on the screen, and then, do a lot of crazy stuffs for you. Such as Force Feedback or translate roms into your language in a few hours.

 

Besides, I have designed a new Feedback equipment to instead the pad.

I will give more details later.

DAPHNE v0.99.7 Changelog (from v0.99.6)

24 Sep 2005

 

- added game driver for Dragon's Lair 2 support (with Dragon's Lair samples).  Dragon's Lair 2 can also be plugged directly to a real LDP-1450 via serial port.

- added game driver for MACH 3 support (with samples)

- added game driver for Us vs Them support (no samples)

- added game driver for Roadblaster

- added game driver for Interstellar

- added game driver for Cobra Command using MACH 3 hardware

- added speech synthesis to Thayer's Quest

- added built-in parallel port support for Windows NT/2k/XP.

- fixed a few bugs in SDL.dll so that YUV hardware acceleration now works on almost all configurations (including most ATI cards).

- added an alternate overlay scoreboard for Dragon's Lair and Space Ace

- added a cleaner set of Dragon's Lair samples

- added support for large files over 4 gig

- added 'home' directory support (so created files such as daphne_log.txt can be created in a different location)

- added ability to disable the log file so it never gets created

- added line blending option to VLDP.  This will help get rid of the annoying horizontal lines some people complain about, at the cost of reducing the vertical detail by half. Some people may prefer this to doing an inverse telecine and re-encoding their mpeg.

- added scanline simulation option to VLDP to give a more arcade look

- added test suite that exercises a number of functions to make sure they work across multiple platforms and hardware configurations

- fixed bug in VLDP where it would lock up if.dat file could not be created

- started removing dependence on Microsoft's C library to avoid including extra DLL's

- fixed bug where Daphne would fail if it is not run from its own directory

- added optional seek delay to simulate the delay that occurs when a laserdisc player seeks to a new frame

- switched VLDP so its uses YUY2 overlays instead of YV12 overlays.  This improves compatibility and image quality.

- added ability to pause any game as long as the disc is playing

- fixed cpu timing so it stays accurate over a long period of time (instead of getting less accurate over time)

- added non-blocking seeking to the LD-V1000 driver to more closely emulate the original hardware.  Previously, everything stopped while waiting for seeks to complete.

- DaphneLoader now properly defaults to 'noldp' mode if the game is not configured

- DaphneLoader now remembers where the window was previously

- added support for DLE v2.1 rom images

- fixed bug in Cliff Hanger driver where long seeks weren't registering a 'busy' status

- added ability to save the static RAM (sram) on a regular basis so that high scores aren't lost if Daphne is shut down improperly (ie powering off the PC)

- added better error messages for missing ROMs to help newbies troubleshoot easier

- unix no longer uses mmap for ogg audio streams because of problems with read-only file systems

- added ability to use a real Space Ace annunciator board with Space Ace by using -use_annunciator from command-line

- improved key remapping parser so it will never crash even if file is corrupt

- added support for more digital joysticks

- added ability to disable joysticks

- added 'sticky coins', which means that coin presses will never be lost even if daphne is in the middle of a seek

- optimized ogg audio callback so that the memory copy functionality is more efficient

- command-line buffer size has been increased to accomodate huge framefile paths

- added a warning to the logfile to try to steer newbies away from using 'noldp' mode
