Steam deck. Not as cheap as an ambernic or raspberry pi, but I’ve been blown away by how painless and plug and play everything is, and I’ve played games on it from every console generation up to ps3 so far, plus modern pc games. Steaminput makes controller settings a breeze even for games or applications that don’t have good input settings. I knew I’d like it before I got one last year, but since then I can’t say enough good things about it, it’s honestly everything I dreamed of as a kid playing video games, almost every game under the sun all in one handheld package, it’s honestly incredible.
