VGA Scaler (240p) for CRT

[MickGyver]

Hi!

I'm trying to get a good image on my CRT using the vga scaler at 320x240p resolution. I'm currently using these settings:

video_mode=320,8,32,24,240,4,3,16,6048

The image is centered both horisontally and vertically on my CRT but the image is cropped on both the left and right sides. Could a kind soul explain what I would need to change in the video_mode parameters to get the image to fit on my CRT horisontally?

You mean using the scaler for VGA cores?

In my case I want to use ScummVM on my 15KHz CRT. I managed to get a non-cropped image with these parameters (352x240px):

video_mode=352,26,34,73,240,4,3,15,7383

It's offset slightly to the right but otherwise it works great.

I know, I'm watching this thread since I'm very interested in this subject.

I was wondering if it'd maybe be possible to use this method to display other non-15khz cores (Atari ST, BB, etc) on 15khz TVs.
