Thanks for the help. I actually saw that video before but nothing in there seems to help. However, I followed your advice and changed the video size font to 16 in order to see the whole screen. Now when I try to save a game this is what happens:

We will use Doom in this example:

When I click the hotkey to save, I get:
“Saved state to slot #0.”

Cool, okay, now I click the load hotkey on my controller:
“Failed to load state from “/home/pi/RetroPie/savestate/Doom (U) [!].state 1”

If I retry to save again I still get:
“Saved state to slot #0.”
But if I now try to make another load on my controller it will say:
“Failed to load state from “/home/pi/RetroPie/savestate/Doom (U) [!].state 2”

This seems like a red flag. It seems like whenever I try to load, my retropie is loading from one integer too high. Like there is an auto interval change.

Is there something I need to do with this line of code?

# State slots. With slot set to 0, save state name is *.state (or whatever defined on commandline).
# When slot is != 0, path will be $path%d, where %d is slot number.
# input_state_slot_increase = f7
# input_state_slot_decrease = f6
