128 pixel high screen #323

Closed sjgray closed 1 year ago

In the geometry menu for "Min V Height" the hardcoded minimum is 150. Is there some reason for this limit? I am trying to emulate an old vintage LCD panel that has a resolution of 480x128 (80x16 text) using a Commodore VDC chip but this 150 pixel limit means I can't get the video to fill the screen. Can it be lowered?

That value has already been reduced to 100 in recent betas, see this commit:

Latest beta here: https://github.com/IanSB/RGBtoHDMI/releases

BTW A new stable release is imminent which will also have that change.

On a sidenote, I'd like to get a profile created for the colour output of the Superboard 600D but I still haven't built mine. I recall from the osiweb forums that you have been experimenting with the 600D colour output so if I create a speculative profile would you be able to try it as I assume your post means you have an RGBtoHDMI.

That’s great news! Looking forward to trying the beta tomorrow and then the release. Yes, I have a few OSI C4P and super board machines and my own colour board. I’d be happy to test for you.

The beta worked great, thanks!
