Trouble W/ Mortal Kombat on K7000

[Rodimus80]

When the game starts, it's showing the game running at:

400x256p 54.707 Hz 15.646 kHz

The game should be running at:

400x254 (H) 54.70604 Hz

I am experiencing audio issues every 10secs or so, like the audio is slowing itself down for a sec.  The game itself is solid, minus the screen wobbling a little.  But that seems to be going away the longer the K7000 is powered on.

GM picks the closest appropriate mode from what's available on your computer. In your setup's case for MK, that is 400x256. As 256 is the nearest multiple of 8 to 254, I doubt there'd be any real difference even if you were able to create a 400x254 mode. The game will still be pixel-perfect, but you'll get an invisible blank line at top and at bottom of screen. I doubt you will notice, especially if you adjust vertical size.

Original arcade games were ONE game per cab, in most cases. So, the operators would put in a game PCB and adjust the screen size to suit that specific game. That's what the monitor's geometry controls are for. If running mame/groovymame, you should not expect every game to fill the screen perfectly, every time you start a fresh new game. Even if you get the video mode and refresh rates etc "just right".

If you have some sound stuttering there's likely something in your audio or video setup making it happen. It might even be something you've changed from default in your mame.ini like triple buffer; syncrefresh; or portaudio. That list is not exhaustive, just what came off the top of my head. The best way to be sure it is "clean" is to delete your mame.ini, generate a new one (mame -cc), then go into VMmaker, click "edit settings", go to tab 4 and make sure you have the export settings box ticked, then click "OK". VMmaker will then update your mame.ini with the CRT settings automatically.

That seems to have fixed it!  Big thanks!  It only took me 30 years, but I finally get to see MKII & 3 the way I remembered it back in the 90s at the arcades..  On a 25' K7000.  I'm so happy right now!!!

UPDATE:  The sound issues came back.  Sounds like the sounds slows itself down for a second to catch up or something.  I noticed I was using Groovymame .258 so I went ahead and downloaded .259 and put it into it's own folder on the C:.  Ran VMMaker and booted up MKII.  Sound issues are gone.

If it happens again try this:

What's new in Switchres 2.002b (June 2021)

- New option -[no]syncaudio: Make audio synchronization (resampling) optional. Default is enabled. Disable to avoid sound wobble with erratic emulation speeds (like that caused by frame delay on some systems).

Is this located in the mame.ini?

with the preceding dash makes the example given a commandline parameter. There should be a corresponding mame.ini command though. Maybe "syncaudio 1" or" "0"
