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.

What you need

Section I - Prep Work

  1. Power off your console

Section II - Installation

Section III - Core Optimization

  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

  2. Press A on your newly installed core to unwrap it
  3. Press A to open it
  4. Wait for it to load, then -> Load Content -> sdmc:/ -> Go to wherever your ROM is located -> Press A to select your ROM -> Choose your core
  • Be patient for your ROM to load, this can take a while depending on file size.
