MEmu Play
A free emulator designed just for weak personal computers in terms of hardware. The distribution is downloaded from the official site and "weighs" only 15 MB. PC requirements are modest: from 1 GB of RAM, a video card that works with the OpenGL 2.0 instruction set, any processor (even Intel, even AMD) that adequately perceives virtualization.
Application functionality:
fine-tuning (processor operating frequencies, memory consumption, screen resolution, root mode, etc.);
connecting a joystick for games;
access to files from Windows to Android and vice versa;
applications with the .apk extension are installed by drag and drop;
launching several Android systems (and different versions) and switching between them;
video recording from the emulator screen is available;
you can install WhatsApp, Telegram, other instant messengers and type messages from the keyboard;
connection to many TV channels is available.
