Ive played this handheld and linked to a TV in gamingmode. I have not had any problems with this game. No problems with full screen ( i don't usaully have the rom in fullscreen, but the game is in fullscreen.) Battery life is within expectiations, You can probably push the battery life further. but really is not needed. Two controllers work flawlessly, am able to changes binds in game. Did nothings other than run this in proton exp.
