There's a sad bit of irony that the year is 2024 and the game console in your pocket could feasibly run anything you want, but the OEM region-locked it again.
But, FWIW, I've been really happy with acmeplus's beta of Batocera Linux on my RG35XX+. My son and I have been taking turns playing through old gems like Pokemon and Aladdin on it, and I'm hoping to finally beat Final Fantasy VII one of these days.
