Change default auto resolutions to custom resolutions

Hi steveggz,

I order to calculate 640x480 as progressive, edit ReslList and make sure the corresponding line is: 640 x 480 @60.0000

By default, 640x480 is defined as @30.000 in ReslList, which produces an interlaced mode. This is done to make sure that there is always a 15 KHz version of 640x480 for regular arcade use.

Using the "MULTI" function in VMMaker will make it ignore the monitor_specs lines, you need to use "CUSTOM" so they are used.

steveggz:
Yes! Vmmaker and groovy work perfectly again.

It was because of a program I tried out called RefreshForce. I thought that I had restored the original settings after I found out the program couldn't do what I wanted.

Now I'm going to try to get 640x480 progressive.

Thank you Calamity.

steveggz:
Great! I'm finally displaying 640x480 progressive.

Is there any way to have the picture a little more stretched out vertically by adjusting some numbers in Arcade_OSD or is it only possible by adjusting the monitor pots?

Calamity:
Glad to hear you got it working.

As for the vertical size, there's nothing we can do about it from the software side, that's a limitation of CRTs and makes it necessary to adjust manually. There are a few monitors that actually do some sort of autoadjustment for the vertical size, but it's usually out of our control (similar to what Sony TVs do).
