Please add the info requested in https://retropie.org.uk/forum/topic/3/read-this-first to the topic. A verbose log (assuming the emulator you're using is RetroArch) may be of help.

@mitu OK, thanks for your efforts, for the time being I'll use different board for retropie. It wasn't just the inputlag, they have usefull feature, but I think I have found an alternative that don't seem to have problem with Emulationstation.

you need to start runcommand (pressing main button when starting the game) change your (Resolution/frequency) to any with 60 hz.

I have a dead snes console and the replica usb controllers.
I'm doing this now.
Moving the /home directory to a usb stick for roms/art/configs and making the SD card OS read only so when my kids just kill the power they won't nuke the card.

it doesn't boot super fast but if you can't wait a few minutes to play a game.......
