Overlays by system (can't change size to fit)

[Ristul]

Hi, I'm trying to get overlays by systems working, I followed the guide on the wiki: link text

Everything seems fine until I try to change the size of the picture to match the overlay. For some reason, when ever I change the values in the config file, nothing happens.

custom_viewport_width = "992"
custom_viewport_height = "720"
aspect_ratio_index = "22"

It doesn't matter what values I put in, nothing changes with the picture in recalbox. I have no idea what to do, any help would be appreciated.

@ristul Hello
Have you tried with : aspect_ratio_index = "23" ?
