Lemuroid is an open-source Android frontend built on top of the Libretro core ecosystem, maintained by developer Swordfish90. It is distributed under the GNU General Public License v3.0 and has 4,371 stars, 366 forks, and 595 open issues on GitHub. Late 2026 is a good time to set it up due to its active development. It is available on Google Play, F-Droid, and GitHub, providing redundancy in case of policy changes. Lemuroid supports twenty systems, each mapped to a specific Libretro core. PlayStation 2, GameCube, and Nintendo Switch are not supported. It requires Android 6.0, 500MB of storage, 3GB of RAM for 8-bit and 16-bit systems, and legally dumped ROMs/ISOs. BIOS files are required for PS1, PSP, and DS cores. It is recommended for managing multiple systems in one library.
