hi,
to get screen res and refresh rate, just parse this info from the -listxml output, but be aware, the resolution is not always width x height, you must also check the rotate tag to get the proper resolution.
Vertical games have the [width info in the height tag and the height info in the width tag.
First, parse the rotate tag.
- if rotate is 0 or 180, the game is horizontal and you can parse width and height tags normally.
- if rotate is 90 or 270, parse width as height and height as width (this is to show the correct resolution.
Easy...
I don't know why MAME does this in the -listxml output.
Just parse all resolutions and refresh rate and store them into two TStringList vars and make sure to remove duplicates. Then you can display them in TComboBox controls (drop-down control), or another control of your choosing.

That's a good solution for single resolution / refresh rate selection.
But if you want to select more than one resolution and/or refresh rate for the filters, the best solution would be to display them in two TListView controls, one for resolution and other for refresh rate.
Also, each entry could have a checkbox so the user can choose multiple resolutions/refresh rates.
TListView have a property to enable checkbox on items (TListItem)... at least in Delphi language it does, but I don't know what language you coded the application. It might be different.

there is no such info in -listxml output. There is no way to know how many colors a game uses, much less scanlines (don't even know what this scanlines info mean).
