Setting up retro emulation on a Steam Deck

How a reader went from zero to a full retro library on Steam Deck using RetroArch and EmuDeck.

A common scenario: a gamer wants to play NES, SNES, Genesis and PS1 games on a Steam Deck. The problem was choosing the right emulators and configuring controls. The solution was installing EmuDeck, configuring RetroArch with the correct cores, mapping controller inputs and enabling cloud saves. The result: a complete retro setup with no original hardware required, playable on the go.
