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.

Section III - Core Optimization

1. Navigate to sd:/retroarch/cores/
2. Select all the uninstalled cores and place them in a new folder at /Retroarch/Cores-Notused/

• Leave any installed cores in the cores folder, these are required for "Load Core" functionality
• If you want to use any of the uninstalled cores, move them from /Retroarch/Cores-Notused/ to /Retroarch/Cores/ and install them with FBI, or use the "Load Core" option within RetroArch
