Lemuroid is a free, open-source emulator frontend for Android. It is based on the powerful Libretro framework (the same core engine behind RetroArch) but offers a simplified, touch-friendly, and unified interface with no complex configuration.

It supports multiple gaming systems (consoles, handhelds, computers) under one app. A BIOS (Basic Input/Output System) file is a low-level software dump from a physical console’s read-only memory chip. It initializes hardware, checks for connected devices, and provides core functions (graphics, sound, input) for games.
