Hi rexel,
Any chance for direct answers to above questions.. will help understand this software better and not muck anything up
Sure!
1) does vmarket list the different resolutions it can run? what does vfreq hz stand for? alot of them around te 60hz mark...
VMMaker installs a video mode list (same as Soft-15KHz) but grabbing the info directly from mame.xml. Video modes will be generated when possible to match native frequencies (usually 15,7 KHz) considering they also need to match your defined monitor specs.
Vfreq Hz stands for vertical frequency in hertzs
Many around 60 Hz, as expected.
2) hfrq = around 15hz... is this 'soft 15khz' equivalent?
15
KHz. Yes, those frequencies are equivalent to the ones produced by soft-15khz
3) there are some 'native' resolutions with no figures shown under hfreq... whats this mean?
It means they are native resolutions created by the driver by default
which we can't remove and you should not use with your arcade monitor because they'll be out of range (take care).
4) when selecting a resolution... in this case 640x480 @ 60i... when i hit enter.. it goes to another screen for adjustments... is this meant to be done via the arcade monitor?
Yes the point of that screen is to do real-time geometry adjustments directly on your arcade screen so using that on a LCD is worthless (that's why I asked it before as I suspected you were still using a LCD).
I think your fear comes from the fact that you still have picture in your LCD which means it's not outputting 15KHz. Does it go out of sync when you select 640x480@60i using button "1"?
For groovymame version use the latest 144u2.013d (
