I get a MATROX MGA MILLINIUM  4MB VGA card from a friend  to check advmame.
this is the very first time i run advance mame.
Once i run ADVCFG to get the device_video_format in advmame.cfg, .
I have got three problems.
1)Every time i saw (green color)vertical lines on the screen.
2)I run advmame on DOS and run a game (Cawing)it was fit to screen
   but still contains those green vertical lines.When i do some changes
   in the advmame options and change color settings to 32 then there 
   were no vertical lines on the screen,while the picture was looking 
   very blur.
3)Many games Speacially neogeo games those are best fit in dmame
   on my PC monitor,they are giving here irritating results.
   these neogeo and some other games are running on short screen 
   with a 58HZ refresh rate which is not supported by my monitor.
What ADVV utility do? 
do we need "device_video_modelines"in advmame.rc?
thanx in advance.
