Is this true? Native resolution 512x480 @ 30Hz for those games. What kind of monitor can do that? GM creates interlaced modes and it doesn't look too good. What would you suggest?

Some Bally Midway games originally used interlaced modes to allow high resolution sprites over low resolution backgrounds. An interlaced mode of 60 Hz only updates a full frame only at a 30 Hz rate, that's why MAME reports that speed and it's perfectly correct.
As a fact GM (just because it can!) renders these game as progressive when you use a 31 KHz capable monitor, but this is plain wrong in terms of accuracy.

So what would be accurate on a 15khz monitor? Interlaced as it is?

Obviously.

Does that mean the original games had flickering?

Sure, as your TV did. Whether flicker was *so bad* on those old CRTs, that's a different story.

Hm, pretty bad on my Polo I think.

New monitors with thinner scanlines have better definition but for the same reason, interlaced modes flicker more. Some old monitors just don't display good interlaced modes, it's like if both fields didn't fit properly. Some users also reported the Radeon X series to provide nicer looking interlaced modes than the HD 4xxx cards. Finally, you can reduce the apparent flicker quite a lot, at the cost of loosing sharpness, by using the -filter option for these games.
