For questions relating to emulating other systems or hardware on Android; note that the "android-emulator" tag should be used for concerns about the Android emulator specifically.

An emulator is a piece of software that mimics the functions of one computer system on a second computer system. Emulation is commonly used to ease testing (such as in mobile development) or to help preserve older software systems, particularly after their targeted hardware has become obsolete.

Note that the tag should be used for concerns about the Android emulator specifically.
