Hi, I'm trying to make a mini retro games arcade cabinet like the one recently made by I Like To Make Stuff on Youtube. I considered using raspberry pi like him, but its too expensive so I decided to use arduino. I already have an arduino uno r3 and basic knowledge of it, so I know how to hook up monitors, joysticks and buttons and how to use them as inputs, but I don't know how to install games onto it. Anyone have any advice?
