Here is a EmuDeck ROG Ally emulation guide to get all emulators set up on your ASUS ROG Ally with the proper configuration, bezels, hotkeys, performance fixes and more.
EmuDeck is a collection of scripts that allows you to autoconfigure your ROG Ally, it creates your roms directory structure and downloads all of the needed Emulators for you along with the best configurations for each of them.
Update: Nintendo has shutdown the Nintendo Switch emulator Yuzu and the Nintendo 3DS emulator Citra.
