Well instead of adjusting in arcade osd I went the route of making the modelines for my CRT actually fit. I still find it hard to understand how it all works, even after 10 years of using GM. Best way it works for me is to setup the resolutions in VMM first and then Mame seperately. Even if the modes are adjusted nice in VMM they are off for me in MAME with the same values, no idea what I'm doing wrong. However, I'm close to what I wanted to achive!

That's the correct route. Just use arcade osd to get the good values for a single mode in each range, then generalize for all modes in the range through crt_ranges.

Make sure there's nothing obvious set wrong. Option monitor custom must be set both in VMM and mame.ini otherwise the crt_range lines are ignored. GM uses its own set of crt_range lines inside mame.ini which need to match the ones in VMM so they produce the same results.
