Citra is the leading 3DS emulator. It has an official Android build that is actively developed. You can find it on the Google Play Store or directly from the Citra team’s GitHub (before the Yuzu/Citra legal takedown – note that while Citra was discontinued in 2024, community forks like Citra MMJ or Lime3DS now carry the torch). Always use community-approved forks like Lime3DS or PabloMK7’s Citra fork.
