I just found out the PSP Go was a thing and I really like the idea of having the screen slide up to reveal the controls. I think this would be a great way to make a more compact version of the Steamdeck. I don’t know about the low profile joysticks though. I’ve never used anything like those before and I’m not sure how they’d feel to use. Maybe it would just be something I’d have to get used to. Regardless, I’d love to hear what other people think about this idea. Edit: I think I should clarify. I’m mostly referring to the style with the sliding screen. I don’t think something as small as the psp would be a good idea either
I was just about to mention the Xperia Play until I read your post. It wasnt the best phone, but it let you play pretty much anything up to the PS1 era on your phone with a physical game pad.
Its crazy that it still seems ahead of some of the android retro consoles you can find today, given the sliding screen and, at least in my option, decent ergonomics.
