Ok....that helped. Its up and runnin' now. Any tips for V games that come up thin looking (dimension wise)? Pacman was the first game I pulled up to check for differences in appearance/detail and it looks better than my previous soft15 setup, but looks a bit "smashed in" from the sides.

Well that's probably because you got used to the other proportions. The ArcadeVGA and Soft-15Khz use 352x288 modes for vertical games but that doesn't actually provide 3:4 aspect ratio on a 4:3 monitor, it's slightly wider, but somehow we've got used to it.

Anyway you can specify different ratios for vertical games by means of the monitor_aspect option. You need to use the same value in vmmaker.ini and mame.ini. Basically it works like this:

4:3 -> default, what you have now
3:3 -> square, vertical games will look as tall as wide
3:4 -> full screen, vertical games will stretch to cover the screen

Now the nice thing is find an intermediate point between 3:3 and 4:3, like 7:6.

I tried the modeline trick, but apparently did it wrong 'cause it didn't work. But before I go any further, does it cause the vert games to be displayed interlaced? If so I'm not going to go this route....the flicker drives me nuts.

boardjunkie:
What I just tried was setting it to flip to vertical orientation. I was thinking of doing this anyway because V games are more important to me than H. So they V games look as they should....and now the H games come up full screen and interlaced. I think the modeline I replaced is causing this. So I guess I need to replace that with the default and see how that goes.

This is *so* geeky ;). A little over my head...quite a learning curve for an old school arcade repair tech.....

Hi boardjunkie,

Definitely the right thing to do if you love vertical games is to rotate your monitor. If you use the option "-monitor_orientation rotate" in mame.ini it will show both horizontal and vertical games at full screen, as it expects you to physically rotate the monitor for each case.

Interlaced modes will be used for vertical games on an horizontal monitor, whenever the number of lines is higher than the value set as ActiveLinesLimit in the monitor_specs line. Usually this is set to 288 lines, so anything above that (for instance 320x224 vertical) will necessarily be interlaced unless you rotate the monitor. Games between the range of 256-288 lines will be possible to show as progressive but at the cost of lowering their refresh rate.

The monitor_aspect option does work, both for progressive and interlaced cases, so give it a try, bear in mind you need to recalculate the mode list for it to work.
