I am curently experimenting with the gba cores in retroarch linux (mgba and vba next) to display the games on my crt using the switchres functionality
I noticed that i have two massive black bars above and below the screen.(i know the aspect ratio of the gba is not 4x3 but more 1.66)
Cheching the video output I noticed that instead of sending 160 or so vertical lines to match the gba the graphic card outputs 200 lines.
Is this a limitation within swhitchres (For instance the lowest vertical res is 200) or is there another potential issue somewhere ?
If this is linked to switchres, is there a way to manually add a resolution to match the gba ?
Thank you in advance
