Sync Refresh / Waitvsync / Triplebuffer changes [Alan Kamrowski II]

 

* It changes the waitvsync code to wait for the beginning of the vertical

blank.  The previous code simply checked if it was in the vblank and only

waited if it wasn't.  This caused 2 problems.  The first is that when using

syncrefresh, if there was enough time, more than one frame can be rendered

during a single vblank.  This is why syncrefresh would have odd behavior

such as the game speeding up or slowing during during less cpu intensive

sequences.  The second problem is that the retrace line could sometimes be

seen because while the code checked to see if it was in the vblank, it did

not check where in the vblank it was so it might be at the end of the vblank

and by time the frame is rendered the monitor could be out of the vblank.

 

* It removes the waitvsync only if game speed is above 95% restriction.

This restriction would only cause waitvsync to vacillate between on and off

depending on game speed.  If someone enables waitvsync and it is too slow,

then it is.

 

* When syncrefresh and triplebuffer are used, MAME would run the waitvsync

code anyway.  The triplebuffer code takes care of this and having MAME wait

for the retrace in the waitvsync code anyway is a waste of time and causes

timing issues on some hardware.  If triplebuffering is enabled, then there

is no need to run the waitvsync code because triplebuffer already does.

WHATS NEW IN VERSION 2.2

------------------------

 

Additions / Changes / Fixes

 

  The splash screen will no longer show twice or more (on multislots) after the backup

    memory is reset.

  The memory card format option will no longer wipe the region stored in the memory card

    on AES hardware.

  The arcade protect setting can now have either the testmode button pressed or HardDIP 1

    on (force test mode) to get access back to the button Codes on the splash screen.

  Made visual improvements to the main memory card manager menu.

  Cleaned up screens and messages in the memory card manager, test mode and hardware test.

  Changed the Cheat database storage slightly. It now takes less space in the Bios which

    is good thing as space was beginning to become quite tight.

  Fixed the AES hardware test code (A+B+D) so it also works after the splash screen is drawn.

  Fixed the hardware error message from disapeering on AES hardware as soon as the hardware

    test button code (A+B+D) was released.

 

Fixes (game related)

 

  Fixed the AES version of 'King of Fighters 2003' from crashing after exiting the ingame

    menu (bug introduced in 2.1).

  Fixed 'Andro Dunos' to start attract mode correctly on AES hardware.

  Fixed 'Andro Dunos' 1up not being able to continue on the last credit in a two player

    game in console mode if started with 3 credits each.

  Fixed Fight Fever to work correctly when freeplay is enabled (start was not responding).

  Fixed garbage in 'Alpha Mission II' bonus rate SOFTDip setting on AES hardware.

  Stopped SVC level select showing in a two player game when in arcade mode on AES hardware.

 

Cheats / CRC Database

 

  Added cheat so that Irtating Maze is playable with 1up joystick (hold buttons B or C

    for different speeds). This cheat has not yet been tested on real hardware.

  Added cheat allowing boss characters to show in AES mode with 'Art of Fighting 3'.

  Added cheat to enable blood in 'Samurai Shodown 5 Special'.

  Added cheats to play as bosses in 'Voltage Fighter'.

  Added cheats so 1up can play as bosses in 'Fatal Fury 2', (can cause crashes).

  Added cheats and crc info for 'Lansquenet 2004' hack.

  Added cheats and crc info for 'King of Gladiators' hack.

  Added crc info for 'The King of Fighters 2002 Magic Plus II'.

  Added crc info for 'King of Fighters 10th Unique'.

  Fixed the 'Sengoku 3' boss unlock cheat to add bosses into the mini character select

    (happens after continue) if the cheat was enabled after a game had started.

  Fixed incorrectly labeled 2up autofire cheat in 'Metal Slug 2'.

Emu#dreams reports that Frank Palazzolo has been working on adding more hardware support to MAME, the Multiple Arcade Machine Emulator. Below is a post from his blog about some of the work he's been getting himself into.

Actual MAME-related work!

 

For those who haven't heard, the speech chip used in Berzerk has been reverse-engineered by "Lord Nightmare"! This is something I've been waiting for for about 7-8 years! I'm sure that the emulation will end up in MAME and PinMAME sooner or later.

 

Because of this, I spent some time over Christmas looking at the analog filters on the Berzerk speech board. (These are applied to the sound after it comes out of the chip.) I finished the analysis, and it should be pretty straightforward to add them into MAME after the chip emulation is done.

 

For what it's worth, I've been trying out Maxima with wxMaxima to do the symbolic math for circuit analysis. I know, I could have used SPICE or something - but doing the math from scratch makes it easier to understand what is going on.

 

After I worked out about half of the math for these filters by hand, I ended up with about 6 pages of algebra. At this point, I figured I should use this as an excuse for learning Maxima. Sure enough, I found an error on page 5. Darned minus signs!

 

The second half of the analysis took about 5 minutes, since the code from the first half was already done, and I could re-use it!

 

For those who care - the filter is a third-order lowpass - a first order lowpass, followed by a second order with a resonant peak around 2400 Hz.
