I have an Anbernic RG35XX H and I really love it. Great controls, runs even Dreamcast games pretty well, portable and good battery life. I wish the screen was a little bigger, but for $50-60 it’s a great value.

I’ll second Bazzite. I tried Pop!OS and had a handful of problems with it, but they all evaporated when I switched to Bazzite.

After switching from win10 to Bazzite, honestly the Linux experience is better for gaming. Incredibly smooth.
