Need help with CRT_Emudrive on Sony Trinitron 27FS120

[Lorien]

Here's the thing I'm setup Groovymame with CRT_Emudriver using the Arcade_15 profile. Adverage everithing works Fine. All Resolution in ArcadeOSD show up fine but for certain games in Groovymame it's picking vsync range that the TV does not really like either get vertical scrolling fast with 400X288P 52.427Hz or vertical bounce 400X256P 54.707Hz.

I was wondering if we could force groovymame to use different vsync range for these resolutions?

Interesting Fact Mortal Kombat 4 also runs at 400X256P but 56.665Hz and does not bounce.

N.B. I'm New to CRT_Emudriver and Groovymame. Also Running latest versions of both as of this post date. 0.208 and Beta15

I found how to fix this with a bit a searching. Took the same resolution in ARCADE_OSD that worked and I copied the modeline to clipboard. then made a nbajam.ini that contains only the modeline for groovymame and it now run it under that resolution / frequency.
