Android Emulator vs MAME

Android Emulator simulates Android devices on a computer so developers can test applications across device types and Android API levels without a physical device. It comes with Android Studio and needs no separate installation. Predefined virtual-device profiles cover phones, tablets, Wear OS, Android Automotive OS, and Android TV. An Android Virtual Device sets the Android version and hardware characteristics, and has private storage for user data, SD card data, and cache. The emulator can simulate calls, text messages, locations, network speeds, rotation, hardware sensors, and Google Play Store access. It supports multiple instances, keyboard mapping, gamepads, and root access. The first launch may take about a minute; later launches can use a snapshot and start faster. Supported systems include 64-bit Windows 10 or newer, macOS 12 or newer, Linux, and ChromeOS. The recommended baseline is 16 GB RAM and 16 GB disk space, with higher requirements possible for newer API levels or larger virtual devices. Android Studio on ChromeOS deploys apps only to connected hardware devices.

MAME is a free emulation framework intended to preserve software history by documenting and reproducing the inner components of arcade machines, computers, consoles, calculators, and other electronic amusement systems. It can emulate over 32,000 individual systems from the last five decades. Alongside emulation, it includes an interactive low-level debugger for investigating software behavior, diagnosing emulation issues, and developing software for vintage systems. Its Lua interface can inspect device state, access CPU registers, read and write memory, and draw overlays, though the API may change without notice. Plugins support uses such as external-program communication and alternate interfaces; included examples are Discord Presence and a GDB Stub. MAME can save and load states, record inputs for playback, and capture screenshots or video. It is available for Android, Linux, macOS, and Windows; official Windows binaries require Windows 10 or later. BIOS dumps and copyrighted software are generally not included. The project is distributed under GPL-2.0 overall, while more than 90% of files, including core files, are under BSD-3-Clause.
