If you're up for some hacking and soldering iron use, the Nintendo game and watch systems can be modded pretty easily to load more games, or homebrew code of your own creation. I don't think there's a pico-8 port yet, but it is a tiny little ARM Cortex-M4 board with a nice color screen, dpad, and buttons that you can load any bare metal code and go wild. There's a lot of good info here: https://www.reddit.com/r/GameAndWatchMods/

Cortex-M7, actually! The STM32H7B0 is a surprisingly capable processor.
The main limitation of the Game and Watch platform is the lack of any standard external interface -- while the system has a USB port, it's only used for charging. I've seen a couple of creative solutions to the problem, but they all require some pretty significant soldering skills.
