I’m trying to figure out how to change box art size for specific systems, particularly the NES and Genesis box art. I want to add gameplay screenshots as the box art but want the size of the snapshot to be that of the SNES/GameBoy box art sizes. Is there a simple way to do this?
Sorry if this is the wrong place to post, I’m relatively new to Raspberry Pi/RetroPie.
Go to etc/emulationstation/themes. Select the folder that shares the name with theme that you are currently using, say it is the simple theme, go to the simple folder. Then go to the nes folder and open the theme.xml. under the MD_image line, change size and Max size to the coordinates the work for you. I hope that works, I can’t check right now, for I am not home. Good luck
