RetroArch is a frontend for emulators, & more. It can emulate up to SEGA Genesis & SEGA CD on the Old 3DS/2DS, and up to PlayStation 1 on New 3DS/2DS.

Most standalone emulators are better than retroarch in terms of performance, if you would like to see a list of recommended emulators then see the Emulators page.

Installation

What you need

• RetroArch_cia.7z (direct download)
