Emulation is a research area that focuses on the development and implementation of software or hardware systems that replicate the functionality of another system. This can include emulating the behavior of computer systems, gaming consoles, mobile devices, or other electronic devices. Emulation allows researchers to test and study systems in a controlled environment, as well as to run older software on modern hardware. Emulation has a wide range of applications, including software development, preservation of digital heritage, and cybersecurity research.
