My systems? The post is simply asking if there is a way to add an image to a .bin file to act as a thumbnail on a selection screen. It’s not a systems related post.
The RetroPie PI image uses the Raspbian Lite distribution as its base, so if your code can run on Raspbian, then it's highly possible it will also run on a RetroPie image.
@mitu Thanks man! I didn't know that. I will start doing that as I'm going to mess around with doom and costume images for the scraper, so all my rom hacks look pretty!
@ghostnappa611
I've just downloaded the image to double check and the hash key matches that of the .gz file. The hash key you posted is from the extracted image which is why it's different (though I can verify still correct for the extracted image), if you do the hash check on the original gz file you will see it matches.
There is no problem with the image file you have. As @ortsac said try another SD card.
@herb_fargus Yes, it is the strangest thing. I did recreate everything except for the rpconfig menu. It shows only the word "rpconfig" instead of "retropie config" and there is no help, no icon in the icon/video window to the right. It works, but is just not pointing to things. Are you saying to look for other es_systems.cfg or go through the entries in that file?
It managed to fix its self. Trying to delete the file another way the whole system crashed and led me to an abort screen. When I rebooted the system everything worked fine.
