#Android #emulators can probably handle all the games, but I dislike the user experience of fiddling with all the different emulators, and their different settings, or faffing with launchers and front ends trying to locate all the right directories. I prefer an #emulationStation or #RetroArch frontend that just boots to a list of games. I'm sick of configuring inputs for every system I want to play. A handheld should be pick up and play.
