Yes, I've seen this repo. It's not the same, because it's only a NES emulator. On the Odroid-Go you have more emulators running like on Retropie.
Because it's nearly the same hardware it should be possible to run (or port) it for m5stack.

I hope somebody will do it. :-)

Hi Guys,

I'm new here and I've just ordered my m5stack. Is it possible to run the emulators from Odroid Go (Go-Play) on this nice piece of hardware?

It should be nearly the same hardware, so I think it should be possible?!!
