Thanks for the response but I’m not quite sure how to pass the resolution parameters to emulationstation.

Do you mean do what the post on 9/02 said:

“settings in the retroarch.conf file like this:
video_fullscreen_x = 0
video_fullscreen_y = 0”

Or the post on 9/03 which had the link and the entry below at the link.

I believe what is happening here is that part of the scraping UI is trying to resize to a negative width because there simply isn’t enough horizontal space for it. You could probably just comment out that line in ComponentGrid.cpp to make it not abort, but it will definitely look funny.”
