@mitu used all the resolutions but they had the same issue. I fixed it by making the bars smaller and modifying some code. Here is what i did. Reference if someone comes with same problem.
First here the two smaller images. https://imgur.com/a/BbOfzr7
I named them gamelist_outline_smaller.png and gamelist_background_smaller.png
Uploaded this files to my pi on /etc/emulationstation/themes/snes-mini/art
then modified the setup xml with
replaced both paths with the new images like this example<image name="gamelist_background" extra="true"> <path>./../art/gamelist_background_smaller.png</path>
since my resolution is using 4x3 i went andsudo nano /etc/emulationstation/themes/snes-mini/layouts/4x3setup.xml
i replaced gamelist outline so it alignscorrectly, with this code<image name="gamelist_outline" extra="true"> <origin>0.5 0.5</origin> <pos>0.7055555555555556 0.5</pos>
