Adding a CRT Adjust option

[mathieulh]

I would like to know if you'd consider adding a CRT adjust option, plenty of people use CRTs with Mister, this option would be useful to both SD CRT TVs and VGA monitors.

Everytime I switch cores I have to recenter the image on my monitor, this gets tiresome, there isn't one perfect setup for everyone across all monitors either since we are talking about analog signals. Having a way to setup the CRT center in the core would allow to have everything work as is with an overscan area as originally intended on consoles/arcade boards.

Jotego's own cores have a CRT adjust so that's possibly something that could be implemented directly into the Mister framework if I am not mistaken.

it's up to specific core implementation.
Generally speaking, core should follow original emulated system video timings including image offsets.
If you want a perfectly centered and scaled picture - HDMI is the way to use.

If the implementation of this feature is not too complex, then I would actually prefer having a CRT adjusting. Better now than later when we get more awesome cores for MiSTer.

I too would like to see this feature added to as many cores as feasible, and if some framework support can assist that, it is definitely worth pursuing. Recent survey results indicated close to 50% of MiSTer users are also using with a CRT. Doubtful they are only using one core, so image centering is a real issue for a material percentage of the community.
