hello, my monitor doesn't support the m72 refresh rate of 55.017606hz, so i've added that doubled 110.035212hz as a custom refresh rate on my graphics card and it seems to work, so please how do i set groovymame up to run m72 games in 110.035212hz and still run at the right speed? (frame doubled) thank you

you may try doublescan in mame.ini set to 1

And? Is that the only setting I need to set? How about setting refresh rate or any other settings?

If you're on Windows
-video d3d
-throttle
-waitvsync
-nosyncrefresh
This should do the trick.

so in the mame.ini:
video d3d
throttle 1
waitvsync 1
syncrefresh 0 ?
that didn't work, screen stays in 60hz, surely i also need to set / force the refresh rate somewhere to 110.035212hz for m72 games? as i'm not using 110.035212hz as default

Yes, I'm just telling you how to make groovymame synchronize properly in that specific case (also add "autosync 0" to mame.ini, btw).
Didn't tell you how to make groovymame pick that video mode since I thought you already knew how to do that.
Your OS will be reporting your custom resolution by 3 integer values, e.g. 640x480@110. So you have to force that mode through the resolution option, e.g. -resolution 640x480@110
That assumes the option -switchres is enabled. But enabling switchres requires you to define a monitor preset that is compatible with the mode you expect to set. This is by design to block unwanted frequencies. So it's not that simple. I'd need more information about the resolution you created.
Since you just mentioned "my graphics card" without a label I'm assuming it's not a supported AMD card, correct? If this is the case, you could just run baseline mame without the switchres complication.
