itch.io

I don't know if this will help but why don't give it a try, clear your xone cache: Turn it off -> After it's completely off unplug it from the power outlet -> Wait 1-2 minutes -> Plug it again and power on -> Check if it works

Sorry for my bad english

Works like a charm, if it doesn't load the roms or the commands don't work or any other problem,  just reload page or close tab. That worked out for me.
