Ask HN: What are the fun projects wroth trying with a Linux gaming handheld?

I own a Miyoo Flip V2, which is a lovely device. I'm kinda bored at playing games with it, so in the past few months, I didn't use it very much.

But it's a very capable pocket machine with Linux in it. I connected it through SSH and it has all basic softwares (and I think we can just add more).

So, I've been trying to brainstorm fun ideas that I can do with it. But to be honest, fun, useful and offline ideas are really hard to come by.

I would like to ask for your help, and see what ideas that are worth trying!
