640x480i?

[retrorepair]

So after several hours figuring out what I needed to do to get my x2400 playing ball (had to set the dotclock in vmmaker to 7.13) I have a new problem.

The standard 640x480 resolution is unchanged. I cannot figure out how to interlace it so 640x480 apps (hyperspin, sfiv, etc) are displayed properly.

I got around it on the desktop by using a custom 640x480x62i resolution but I can't see any way to make other apps chose this res too.

I tried installing soft15khz and removing all but 640x480 and above, but that ended in disaster and garbled my display.

Is this normal behavior? Everything else so far is great. I had to make up ini files for the midway wolf/Y/T unit games but everything else seems to work great.

Never mind, I changed the monitor type to "GENERIC" in vmmaker and all seems well. I knew I'd figure it out as soon as I posted on here 

Thanks Calamity and bitbytebit for all your efforts, PCs never looked so good on arcade monitors
