@shylock since more or less every videogame supported by retropie is in 4:3, you're always going to get borders on the top and bottom (rather than the left and right that you would get with a 16:9 display. integer scaling won't make a difference.
with vertical MAME games it would be a nice fit, though: smaller borders on left and right than (un-rotated) 4:3 or 16:9 screens.
you'd also probably need to get a custom emulationstation theme done, unless someone has already done a square one, otherwise it's going to a look a little funky it think.
@mitu Thank you so much. This solved my problem. I never knew there was such trouble just copying files. And thanks again for the advice, copying over wifi and ssh 10.000 small files is really a bad idea.
If you have another controller, then this might not be the same problem. If this is the case, then I suggest you start a new thread, with detailed descriptions of your hardware, software versions, log file entries etc.
@cyperghost got it. I am attempting to change my setup from a nespi case to an onoffshim with a non momentary switch. I used your instructions, to setup the onoffshim, but the system cuts power as soon as i press the button to initiate the shutdown script. (No 3 blinks, just off).
Could the original install of the raspi-gpio for the nespi case impacting things?
Feel free to use the photos. I threw a towel down on the table to stop screws and bolts from rolling around. So, I don't really have a blue and white striped table top. lol. I had to pause the video every couple minutes to allow myself to catch up with the video and to take pictures.
